Erik, 2008 BMW K1200GT
I just wanted to say thanks! I finally got the booster plug installed on my 2008 BMW K1200GT and what a difference.
It's incredible how one change can make such a difference.
No more twitchy throttle or thinking I was about to stall when running at 2000 to 2300 rpm.
I read all the praise for the booster plug before I ordered one, but it's still wonderful to find that my results are the same as all those other people.
Combined with an Oberon Clutch Slave Cylinder Kit to smooth out shifting and reduce the force required to engage the clutch and I have a whole new bike.
Thanks very much for the great product. It truly changes the whole character of my bike.
Tony, 2014 BMW R1200GSW
Just wanted to tell you I installed the booster plug on my 2014 r 1200 gsw and the bike is now running flawlessly in the first three gears.
Cruising in 3rd at 30-40 mph without surging and off road it helped low speed long fire road cruising.
The bike idles so smoothly and the popping when down shifting is 95 percent better.
Thanks for making such a great product.
I went from Las Vegas where it was 102 then to Utah mountains where it got to 50 degrees and the booster plug was perfect.
Jascha, 2012 Triumph Tiger 800
I got the boosterplug last friday, earlier than expected, thanks for shipping it so fast.
Installed it on the weekend, used the opportunity to do some maintenance. Once the bodywork and tank are off, installing the plug literally takes a minute.
Change was immediatly noticable, lower rpm feel much better, i can ride in 5th gear at 40kmh with nearly closed throttle and the bike still is very smooth.
Most of the decel pops are also gone now, sound is a little deeper and less raspy.
Oh, and i can start in second gear with very little throttle. Starting from a traffic light there is nearly no hesitation anymore when opening the throttle.
All in all i am very pleased with the result.
Nathan, 1994 BMW R1100RS
Hi I bought a booster plug from yourselves and I cant believe the difference it has made to my BMW R1100rs.
Its faster, smoother, better mpg and doesn't have the horrible surging that haunts that model.
Money well spent, took 3 minutes to fit, Brilliant!!! Thanks guys!
Mark, 2004 BMW R1100S
Received and installed the Booster Plug on my 2004 BMW R1100S ... and it works GREAT!
Smoothed-out the minor low speed 'surging' problem immediately. THANK YOU!
I had initially read about the Booster Plug some months ago, but figured it was just another 'snake oil' product (American euphemism for 'placebo'). Then Motorcycle Consumer News came out with an actual evaluation of your product, and gave it their top rating ... so I decided to try it. Glad I did.
Thanx again, I'm a happy customer.
Simon, 2006 BMW K1200S
I am unbelievably pleased with my 2006 BMW K1200s upgrade; it really does do what it says on the tin and was simple to fit.
Many thanks, it is totally genius and fixed an easy 90% of the issues such as bucking, bad gear changes and lack of control at slow speeds!
Bloody brilliant! :-)
Gerd, 2002 BMW R1150RT Single Spark
Ich bin begeistert!
Gerade um die 3000U/min war meine RT noch recht "störrig"!
Auch der Übergang vom Schiebebetrieb in den Lastbetrieb, also beim öffnen der Drosselklappen war sie sehr "bockig"!
KFR Konstant-Fahr-Ruckeln oder auch Mager-Ruckeln war bei dieser Drehzahl, trotz feinster Einstellungen, immer noch spürbar und auch störend.
Nach dem 10 Minütigen "Einbau" des Boosterplug und einer ausgiebigen Probefahrt kam mir der Motor "wie in Watte gepackt" vor!
Sanfter, ruhiger Motorlauf, Ruckfreie Gasannahme, 50 im 2ten Gang ohne KFR
Zusammengefasst: Wie ein anderer Motor, jetzt macht fahren noch mehr Freude!!
Vielen Dank. Der Boosterplug ist ein Top Produkt und auch noch qualitativ hochwertig gefertigt.
Daniel, 2008 BMW R1150GS Adventure
Just wanted to say THANK YOU for that amazing product!
Turned my BMW R1150GS Adventure into a more agile tractor on two wheels.
Joking aside - I could not believe what a difference it makes.
Colin, 2008 BMW R1200RT
Back in the '60's I rode the 600 cc version and it was as smooth as silk. Imagine my horror when I bought the 1200 cc 2008 version - lumpy idle, rough acceleration, and huffy over run.
Took about 40 minutes to install the Booster Plug - mostly getting the fairing on and off and deciding the best place to strap the probe. Ended up putting it against the lower frame below the seat.
Result - miraculous! Smooth idle, smooth acceleration, easy slow speed riding, and no huffing on the over run. Totally new bike and a joy to ride.
Thank you for doing what BMW should have the capability to do but clearly do not.
Richard, 2005 BMW K1200S
Carried out over £2,500 worth of warranty work with BMW main dealer to diagnose issues with exhaust puffing and hesitant throttle at lower revs. All to no avail.
They finally said "They all run like that Sir!" As a daily commuter in heavy traffic, my bike was exhausting to ride and set my nerves on edge.
The plug took 45mins to fit and had an immediate positive effect.
No more exhaust puffing and it's now possible to hold rock steady at 10mph in 1st gear with no bucking bronco syndrome.
Acceleration is discernibly smoother and the engine no longer feels lean and dry under load.
Tom, 2013 Triumph Rocket III Roadster
I installed the booster plug in my 2013 Triumph Rocket 3 Roadster and I am very pleased with the results.
The bike has improved acceleration and power! It delivers on its promise and does what it says.
Don, 2006 BMW R1200RT
I received my Booster plug today, and that was very fast delivery.
I just want to confirm what many others have said about the Booster plug.
I was on the verge of changing the bike it was that bad.Now it,s the terrific bike that it was meant to be. What amazes me is how BMW can allow a bike that has these known problems to go to market.
Thank you for a brilliant piece of Electronics.
Christian, 2013 BMW R1200GS LC
I do have to inform you about the reception of the booster plug that immediately got installed, and the performance was overwhelmingly good!
What an exquisite product this is! My R1200GS LC did even better that it usually does, where all your promises where fulfilled.
Mike, 2007 BMW R1200R
I wanted to get some miles on her before I sent you a thank you.
Everything your site states is true ! From the moment I installed your plug to today the bike runs better, sounds better and mileage has improved.
Told everyone that will listen that they need to install one of your plugs on their bike.
Once again, thank you for the new bike. Please keep up the great work.
Dave, 2008 BMW R1200GS
Wow, I can't believe the difference Booster Plug has made to my bike, it feels like I am riding a new machine.
The power has increased and the bike runs smoother in all gears, from city driving to cruising on the highway.
I could swear someone put in a new gearbox!
To top it all off, it was also easy to install.
Richard, 2010 BMW F650GS
After a few rides the bike now feels like the best I've ridden rather than almost the worst, and that's after 49 years riding experience.
Do not hesitate to fit this kit and believe what you read about it, it works!
Danny, 2014 BMW R1200GS Water Cooled
All is well with the new Booster Plug install on the new water boxer ('14 R1200GS).
As with my previous '09 R1200RT, I'm loving the civilized manner in which the motor can now handle low-RPM cruising in 2nd or 3rd gear (such as when going through a town) - as you know, no jerking or complaining, and I don't have to go through town in 1st gear just to make the engine behave!
Other improvements include the "magical" smoother shifting (necessary, even with the new gearbox and wet clutch) and quicker application of power with throttle.
Anyway, on the whole the improvements are palpable - not as dramatic as with the earlier bike, but this bike was more tractable to start with.
As I told you before, back when, "Well done!!
Chris, 2006 BMW R1200S
Well, your Booster Plug works well!
I fired up my bike Saturday; throttle response is a lot better, the idle is smoother and the exhaust note is a lot crisper then with the FRK. Good first impression for sure. (BoosterPlug Editor: The FRK is an agressively advertized plug & play device that despite the praise and promise is just a fixed resistor - see the "The Alternatives" section on our website for more information)
I took the bike out for the first ride on Sunday, 5 to 8C only. Low end performance, 2 to 4 grand is a lot better, whether the engine is cold or hot. Significantly better when the engine is hot, just as we thought it would be.
Above 4 grand it pulls very well, very smooth power delivery, whereas with the FRK it would come on the pipe so to speak around 6 or 7. Almost like a step in power. Not that it was bad, now it is just better.
The rough running with a hot engine in traffic, appears to have gone, but we will have to wait and see how it behaves once summer gets here!
I am happy. Thanks mate!
Steve, 2014 Husqvarna TR650 Terra
Just wanted to drop you a note to say that I just received my booster plug for my 2014 Husqvarna TR650 Terra which was almost unrideable due to a flat spot and poor idling.
The dealer said the ecm was programmed with the latest 2014 settings and it "should" be ok.
I installed the booster plug last night in around 30 minutes and Wow, instant fix, the bike has no flat spot, idles perfectly and is transformed.
Thaks so very much.
Pepe, 2007 BMW R1200GS
Just received and installed the boosterplug. Fantastic is the only way to describe the transformation.
Here in south Africa 70 percent of all bikes over 1000cc are gs1200 BMW, and they all suffer from a lean condition making them horrible at low speed.
Your packaging, product quality and customer care are exceptional.
Many thanks to you and your staff.
Steve, 2008 BMW R1200GS Adventure
Went out for a ride today – the first time with the Booster Plug fitted.
WOW ! what a difference………, 95% gone is the low speed surging ! I could now travel in the UK 30mph speed limits comfortably rather than having to run in a lower gear and higher revs to minimise the surging.
Hard, smooth acceleration with the Akrapovic 2-1-2 system, no hesitation or delay. Pulls stronger in higher gears, not having to gear down for fast overtaking as in the past.
The bike is transformed, it feels so much smoother and responsive, should have fitted one years ago.
Lars, 1997 BMW R1100RT
As someone who is totally blank and ignorant of mechanics and electronics, I am very surprised with the Booster Plug! I expected I could not even install it on my bike and definitely not in 10 minutes as mentioned. Honestly - in fact, it is much easier to install this BoosterPlug on my BMW R1100RT 1997, and it only took under three minutes if not less!
First, I took the seats of. Then, just in front of the battery (under the driver's seat) the air intake filter is located with an unmistakably cord. I unplugged the cord and inserted the BoosterPlug there and connected the other end of the BoosterPlug cable to the the original cable. Then I hid the new sensor on the right side right of the bike on the inside of the cover right at the air intake. Then I refitted the seats and voilà - the bike is ready for take-off.
I promise you, the bike is working as brand new and way better. Cold start is significantly improved, and acceleration and throttle response is excellent - my bike is reborn on steroids and purrs affectionately when we ride.
I was a little unsure about the purchase but thought that with so many positive responses it was worth taking the chance. And indeed it was! Especially since the installation was even less technically complicated than I expected and the effects is so pronounced and clearly present! This is how the bike was supposed to be!
So do yourself a favour and indulge yourself into the project - you will definitely not regret and you will then laugh about having doubts!
Frank, 2006 BMW R1200RT
I thank you for your fine product.
It completely removed the mid-range ‘flat spot’ on my 2006 RT 1200 BMW and made me very happy !
After the installation of the Booster Plug over a year ago I never think about it. Very reliable and does not fail!
I would also like to mention how well thought out, nonintrusive and surprisingly easy your product is to install.
I am still impressed by the upgraded performance of my Beemer and would recommend your product to everyone.
Your Booster Plug is by far the best accessory product I have ever purchased, thanks again!
Steven, 2013 Husqvarna 650 Terra
Just a short note to say the BoosterPlug is brilliant on my 2013 Husky Terra 650, providing quicker, smoother acceleration and much better response at lower speeds.
I spun the rear tire three times accelerating out of slow curves within the first 30 minutes of riding with the BoosterPlug, something that rarely happened before.
The Terra has morphed from a nice trail tractor into trail-worthy Motard...thanks!
Peter, 2007 BMW R1200S
Just wanted to let you know how happy I am with the BoosterPlug.
It arrived yesterday , two weeks after I ordered it, which is not bad from Denmark to Australia.
I fitted it last night to my 07 R1200S and I'm happy to say it does all it claims to do.
Fitting was easy as can be and so far I have a Smoother idle, no flat spots and it just runs better all round.
I will be recommending this product to every BMW owner I meet. Thanks again for making my Beemer all it can be!
Brian, 2003 BMW F650 CS Scarver
Received the Booster Plug in 6 days (USA)
WOW what a difference, night and day.
The throttle is smooth and NO SURGING!
Any single spark F650 this is a must buy!
Michael, 2013 Husqvarna 900 Nuda R
Thank you for making such a top quality product that has transformed my new bike.
I had resorted to using the decreased power map or rain mode around the city. Fueling below 60 km/ hr was horrible on partial throttle. Surge and snatchy throttle made low speed traffic and cornering really hard work.
The booster plug has transformed my bike. It feels much more compliant at low speeds and it will pull very cleanly through to redline. Gear change is easier.
Less than weeks postage to Australia and very simple quick self install.
Excellent service, well made product with very pleasing results. Thanks again
Marius, 2004 BMW R1200C Montauk
Thank you ever so much for this incredible device.
I bought BP couple of years ago for my 01 BMW R1200C Montana, but never got around to install it. While moving from Connecticut back to Texas I came across the gizmo when packing. Since I already sold the the bike, I decided to install BP into my beloved 04 Montauk.
Took it for a brief spin: it literally took my breath away!
I don't want to be redundant with my comments, but the bike is quite different, especially shifting gears, not to mention the overall agility.
Thank you again.
Thomas, 2011 Triumph 1050 Sprint GT
I recently bought the Booster Plug for my Triumph Sprint GT.
Being here in warm Florida, along with my aftermarket pipe made the bike run rough on hot days, along with popping on deceleration.
I almost sold the bike.
Your fix for this is real! Smooth running even on the hot days, and much less popping too.
Thanks for making me love my bike again...!
Alex, 2013 BMW F800GS
Booster Plug installed on my '13 F800GS and immediate change apparent.
Off idle, roll-on acceleration, and mid range response all much improved.
I took the bike onto a dirt road Sunday and noticed that when exiting turns and rolling on the throttle it was much easier to smoothly break the rear end loose in order to power out of the turn.
Very happy with improved performance.
Andy, 2009 BMW K1300S
Never been a "testimonial" kind of person; but, you deserve another one.
At the recommendation of a BMW tech, I had him install a Booster Plug in my '09 K1300S during a recent 12,000 service to address poor idle/stalling. Bike has full Akrapovic exhaust.
Results after 170 miles of varying riding: idle steady at 1050 no matter what I did. No stalling. Intuitive throttle response any rpm/any gear. Smoother power delivery. Smoother shifting (how does that work?) especially from 1st to 2nd.Downshifting even smoother. New bike, better than ever.
Congratulations on inventing something so simple that really does work. Now to work on that engine that runs on air.........
Michael, 2009 BMW HP2 Sport
Each year I buy hundreds of things over the Net. When I bought a new to me '09 BMW HP2 Sport locally, I quickly realized that I would rate the in town drivability a poor D-. It needed help….
I have ridden sport bikes and motorcycles for 40 years and have worked on them and sports cars for the same amount of time.
I never write feedback letters unless I am shocked and awed. Haven't written one in several years.
But when I pay for an item on Friday from frickin' DENMARK and I get it in NorCal on Monday, I notice.
I installed it today, taking 3/4 hour so I could route the sensor wire under the tank. Thanks for making the unit smaller as it fit even on this track bike where I literally have no room even for registration papers.
I then test drove it today. Off throttle bucking is gone 90%. Low speed downshift roughness gone 90%. Low speed upshift smoothness better by 75%. Idle strength better by 100%. Rollouts from rest stronger and more confident; no need to over rev the motor to get away without bucking or possible stall.
In all one of the 2 or 3 best products I have ever used over 40 years of mod experience.
It actually does what you and others say it would….
I now rate the in town rideability as a B+/A- up from a D- --compared to a Honda 6 cyl. Valkyrie I had which was of course super tractable in town.
It has transformed the bike.
Ozgur, 2000 BMW R1200C
Finally I installed my booster plug on my r1200c.
Fantastic performance on acceleration. Fantastic performance and smoothness on the road.
Thanks. Best thing that I ever bought.
Willie, 2013 BMW R1200GSW (Water Cooled)
I promptly installed boosterplug on friday when I returned home and then rode about 100 miles.
I definitely noticed that the bike runs smoother -especially at lower rpms. I can now lug the engine with less probability of stalling.
At higher rpms noticed much less jerkiness in the motor. Engine idles much smoother too.
Definitely a worthwhile investment. It makes a fantastic bike even better.
One problem: I've already become used the additional smoothness -and i love it- that i want even more. Not complaining - BP is a terrific product and an outstanding value.
As on my k12s, the BP may prove to elevate the enjoyment of the gsw more than any other purchase -and i've already spent thousands of dollars on accessories.
Stas, 2003 BMW R1150GSA
I’m not one to write in about products but I Have TO SAY I WAS DELIGHTED with my Booster plug that arrived today.
I did a lot or research on the device especially on the BMW forum and as we all know the 1150’s are a little agricultural – part of their appeal I think – as they are reliable and solid.
But the hesitancy on idle and vibration is tiresome and shifting can be “tractor like” and I was hoping that the Bosster Plug would help here.
Well I am glad to report after a quick 5 minute – yes I timed it – 5 minute install and a test ride in the Rockies I am delighted with the upgrade and would say it was certainly money well spent.
Thanks for a great product.
P.S. I made this video (helps that I speak Polish too) to show the install. The video was done on a R1200C even though my own bike is a GS from 2003!
Leonardo, 2010 BMW G650GS
I got very interested in this product as the technical explanation was very convincing to me, but before any purchase i wanted to check if my G650GS was mixing as lean as they claim. So i paid for a dyno run, and i was surprised how lean they work, so i gave it a shot with the Boosterplug.
After the installation (which was very easy by the way), the bike felt more punchier with a beautiful torque in the mid range. Not overwhelming but it definitely felt different. Response to the throttle feels a little more accurate.
Off course i paid another dyno run to check what it actually did and the mixture indeed got a little bit richer. Originally it was around 15:1 and now it is around 14.3:1 (This looks like the Lambda sensor on the Dyno have not been calibrated recently - No engine will run at at an 15.0:1 AFR. /Jens/BoosterPlug.com)
I wasn't expecting additional horsepower from this, but surprisingly i got +2.4 whp and +2 lb-ft of torque which you can feel.
My bike lives at 8500 ft above sea level and results are noticeable, but i traveled to some place almost at sea level and a felt in a complet ely different bike. I've traveled at this heightbefore but this is the first time i felt my G650GS so much punchier.
Thomas, 2008 Triumph Tiger 1050
I wonder why your site only have BMW Testimonials, but I can say that the BoosterPlug works perfect on my Triumph Tiger 1050.
The engine is a lot more "clean" when riding at a constant 80-100 KMH, and throttle pickup after engine braking is without hick-ups.
A remarkable difference and a big improvement.
Chuck, 2000 BMW R1100RT
I purchased this for my 2000 R1100RT and after the extremely simple installation received immediate improvement at all RPM's, fuel milage and it brought my bike back to "life"!
Thank you for making a GREAT product!!!
Jimmy, 2013 Husqvarna TR650 Terra
Bought a Booster Plug for my Husqvarna TR 650 Terra.
Easy installing and makes a good improvement of throttle response and the bike pulls harder thru the whole rev range.
No more stalls at low rev.
Well spent money.
Austin, 2013 BMW R1200RT
Although I don't have a lot of miles on the bike since installation your product works as advertised.
Installation was pretty much idiot proof. The temperature probe ended up routed up near the steering top end away from the engine heat.
The 2013 R1200RT engines in the US run so lean at idle they sound like they're about to start detonating any second. Throttle response from idle up to 2,000 rpm is 'lumpy' and 'jumpy'. After installing your product all that is gone.. very smooth power from idle.
On my first test ride I got stuck in a traffic jam. Air temperature was about 37.5C... miserable hot and humid. The air/oil cooled BMW engine will typically start to run a little hot after 15 minutes of idling along at that temperature. I notice that the temperature stayed down... likely the slightly richer mix helped some.
Power and "pull" is improved from about 2500 - 5500 rpm. I should note that I installed a K&N air filter while I had all the plastic off. I suspect that some of the increase performance at higher RPM was influenced by the K&N air filter flowing more air to the engine.
At any rate so far, so good. Count me as a satisfied customer.
Roland, 2009 BMW G650X Cross Country
Bought a Booster PLug for my G650X a few months back.
It has transformed a nearly "unrideable" motorcycle into one that does just what it is supposed to do.
Before the Booster Plug, after the bike warmed up you could literally not take off from a stop w/o the motor nearly stalling. Perfect now!
I cannot understand how BMW could sell a bike that acts this way.
I had an R1100R a while back and it had a pretty severe lean condition, but not as bad as this bike.
Had I had a Booster Plug for that bike it would have made a world of difference, and I probably would have kept it!
Ian, 2010 BMW K1300GT
I have just fitted a Booster Plug to my BMW K1300GT.The bike had been running very unevenly from tickover to low revs to the extent that on warm days (about 14C and above), when the bike is warm/hot, it is most uncomfortable to ride due to engine surges and stalling.
I previously had the machine dyno'd and was aware of the very weak fuelling at low revs and believe this to be at the root of the problem.
A Power Commander seemed an obvious fix, however, whilst researching this I came across the Booster Plug.
To be truthful I was a bit sceptical at first. As a professional engineer, though, I decided to look at the claims made for this product. 'Recalibrating' the air temp sensor to indicate a lower temp to the engine ECU is not a new idea - but by temperature compensating it and taking advantage of the ECU closed loop response time to react to increased fuelling did seem to me to be a rather smart solution to the weak fuelling problem this, and so many other bikes, seem to have.
Satisfied that this product might just 'do it', I made the investment! Installation on a K1300GT is not a 5 minute job since the fairing needs to come off and the fuel tank lifted! Non the less, this was done - and the result?
Amazing frankly!! The surging, stalling problem have cleared.
Not only that, but throttle action from idle to low revs is much smoother and this makes town riding much more pleasurable and safer.
Not only this, but the absence of surging on low throttle in some corners means that the bike handles so much better in these situations.
If this wasn't enough, the machine pulls better from low revs and is, overall, much smoother.
It's been said by many before - but the bike is now doing what I would have expected it to do.
So, to those with misbehaving K1300GTs not quite wether to take the plunge, my experience is that the Booster Plug does have a most positive effect on the problems generally attributed to weak fuelling, particularly at low revs.
So, well done - Nice product!!
Feri, 2010 BMW R1200R
I have installed the booster Plug on my BMW R1200R. The change was subtle but remarkable.
Mainly at low speed and low revs the bike has more power and reacts a lot smoother when you change throttle.
A nice addition that improves my ride.
Feri made a very nice installation picture series available here
Jerome, 1999 BMW K1200LT
My bike is now working properly again!
It now runs properly at low revs, accelerating and on downshifts and this makes a huge difference in town.
The booster plug sticker is now proudly displayed on the lower fairing.
Thanks for this magic piece of kit.
Mike, 2011 BMW R1200GS
I let a friend ride my 2011 BMW R1200GS last week at night to see what he thought about the Krista lights I'd installed.
When he returned he was amazed how well my bike performed and was disappointed that his 2009 R1200GS did not perform as well as mine.
Needless to say I need to order a Booster Plug for his '09 R12GS
Kim, 2003 BMW R1100S Boxer Cup
I just installed your Booster Plug on my 2003 BMW R1100S Boxer Cup.
I was a little skeptical, but now... it makes the throttle response better, traffic driving is definitely better than stock.
Full throttle acceleration is now as a 1+ liter bike should be... better than sliced bread.
Mark, 2009 BMW F800GS
The boosterplug arrived today and I have just installed it.
Took the bike for a test drive and WHAT A DIFFERENCE!
Wow, you have really restored my faith in my 800GS.
Thank you sooooooo much!
Mark, 2013 Husqvarna TR650 Terra
After installing the booster plug on my 2013 Husqvarna TR650 Terra the unit did everything it advertised.
It has an idle now that is steady and doesn't sound like it's going to stall.
It never stalls now when applying throttle.
And it just pulls harder thru the rev range.
Bottom line------it runs like it should----money well spent.
Bob, 2012 BMW K1600GT
The improvement in throttle response is significant.
Gone is the requirement to slightly rev the bike when letting out the clutch. It makes the fly by wire throttle that always had a remote feeling act like a good old cable system, as any throttle movement gives instant feedback.
The bike is without a doubt snappier and more responsive. The highway fuel economy did not seem to be affected over the 5000 km that I put on since the install. The in town fuel economy may have gone down some but I think this was because the bike was more fun to ride and was probably a result of just using the throttle more aggressively.
Over all I am very impressed. The running quality results are impressive and the install was quite simple with the factory style plugs.
Ordering was easy and delivery to Canada was quicker than expected. Customer service was excellent as all pre-order questions were answered clearly and in a timely manner.
Peter, 2011 BMW F800R
I just wanted to say thanks for the best addition to my bike I didn't know I needed.
I fitted an aftermarket air filter and pipe to my bike and it was a bit snatchy at low revs, but I thought I could manage that with a good right hand control. When I fitted the booster plug I got a whole lot more than just the low rpm improvement - it gave me back the character of an upright twin like I remember from the old days.
The power is better across the whole rev range, low speed engine response is excellent, and now my bland beemer feels like a real bike!
Thank you for inventing this device, it should be issued with every f800r when they leave the shop :-)
David, 2008 BMW R1200GS
I installed booster plug on my 2008 BMW R1200GS recently.
I was stunned by how much the low end of the bike smoothed out.
The hesitation at low speed was gone completely and overall the powerband is much smoother.
Great product! Thanks......
Bob, 2002 BMW R1200C
Wow! Installed your BoosterPlug today - and what a difference from yesterday, excellent.
About 20% better acceleration off the line; no more back-firing during engine breaking; no noticeable lagging when accelerating when at low revs in a higher gear. Idle at a stop light is smoother - thanks!
Best $150 I've spent on my bike so far!
Steve, 2004 BMW K1200GT
I wanted you to know that I completed the Booster Plug install this morning and, despite only having driven a few miles to get some gas, feel confident enough to let you know it's been a success.
I've been wanting a "better" K12GT since I bought it in 2008 and you have helped me achieve that in a way that nobody at BMW motorcyles was able to.
On the initial start I noticed that the idle speed was a hair over 1000 rpm and the exhaust smelled a little richer.
Previously the needle would have bounced between about 800 and 1000 and if I cranked the throttle open I could easily stall the engine. That doesn't feel possible anymore.
It's smoother and requires less clutch riding when setting off.
I purposely pushed the bike up a short but steep incline in 5th and opened it up. Whereas previously it would have done it but said "are you serious?" it now it does it and says "whatever"!
Ladd, 2002 BMW R1150R
I'm happy to report that the purchase & installation of your Booster Plug for my 2002 R1150R has proved to be everything as advertised.
Tom, 2006 BMW R1200RT
You must tire of all these grateful emails.
I installed the BP in less than an hour because of the fairings (R1200RT) and tested the idle before reassembling.
There was a noticeable and immmediate improvement in the cold idle.
I took the bike out today in hot weather around the San Francisco Bay Area and it performed smoother, than ever before.
I too noticed the smoother shifting. This product is a must!
Thanks for making my ride more fun.
Bob, 2012 BMW R1200RT
I just installed the BP on my new 1200 RT and I am impressed. The bike has been transformed.
No splitting or sputtering, incredablely smooth and better power.
It actually reminds me of my old R90 I had back in the 70's when the carbs were sync'd and plugs were new.
Thanks for a great product. It is the icing on my RT cake!,,
Eric, 2007 BMW R1200GS Adventure
I received the booster plug today. Installation on my R1200GS Adventure took all of 20 minutes including drinking a diet Pepsi and eating half a sandwich prior to start up.
I admit I was very skeptical that this device would work as advertised.
Happily I was wrong. Cold start up was instant and noticeably smoother.
I rode it in 105 degree F heat today. The occasional knock due to heat was gone and driving around town in stop and go traffic was much smoother.
Consider me another happy customer.
Walter, 2000 BMW R1100R
Love the plug!
The power curve flat spot is completely gone and less herky-jerky at low speeds also!
Oh and 30 second install on my 2000 r1100r and 8-day shipping from europe to Alabama.
Thx for a product that works as advertised!
Jonas, 2011 BMW F800GS
After I put a K&N filter in my bike it started to puff a lot on deaccleration. The idle was like a rollercoaster.
BUT with a BoosterPlug it was a NEW bike!! Puffing is totally gone, acceleration is smooth a nice. Actually the bike runs better than original!
All I can say about the BoosterPlug is that I LOVE IT!!!
Thanks for a super fast shipping, 3 days to Sweden!
Guy, 2005 BMW R1150RT
I am speechless; my first comments are Wow, Wow and Wow again,
I received the device at work and installed it during my lunchtime in less than 10 minutes with a tie wrap as a single tool.
I was very skeptical that this device would work as advertised. Happily I was wrong. Cold startup was instant and noticeably smoother. The motorcycle is smoother and alive at all RPM.
It is so much better than before that it makes you wonder why BMW does not tune the motorcycle to match this setup, it feels like someone have changed my engine for a better one.
There is one improvement I don’t quite understand; shifting gears is much smoother and improved since this device is installed, can someone explain why? (We had quite a few customers reporting improved gear change with the BoosterPlug, and the only explanation we can come up with is that the softer throttle action may ease up the gear change. /Jens /Boosterplug.com)
I am a very happy customer and I just can’t believe how much better my motorcycle feels…
Peter, 2008 BMW G650XCountry
Just wanted to say that you have an excellent product - I have bought it some time ago but just now I got around installing this wonderful contraption.
The bike got much more "user friendly" as far as I am concerned. Clutching between 1st and 2nd is much easier, in 1st the bike is more agile which is important in heavily congested city traffic, 1st and 2nd gears feel like being considerably "longer".
I am a newbie rider - fairly recently I have switched from automatic 50 ccm scooter to BMW G650X Country and manual clutching was the biggest challenge for me especially in stop and go traffic.
The funny thing is that in my case it seems to save fuel rather than increase consumption. Since I have booster plug installed my fuel bill decreased by 10%. My own theory is that easier clutching and "longer" low gears results in less riding in low gears which in turn decreases fuel consumption.
Andrew, 2005 BMW K1200S
Got the plug the other day and installed it yesterday. I pulled out of my driveway and immediately felt the difference.
No surging or choppiness in low gears at part throttle, much smoother in all gears and the 500 rpm flat spot around 3700-4000 rpm is gone. The bike feels like a different machine.
Really dramatic difference for very little money, the best improvement I've made other than a $2200 Ohlins suspension.
Dan, 2011 BMW R1200RT
I just wanted to say thank you for being great to do business with. As a non-mechanic with your simple instructions, I had it completely installed from start to finish in about 30 minutes.
The improvement on the bike’s performance was immediately evident, particularly at lower idling speeds. The bike used to cough when accelerating at lower speeds which the BoosterPlug virtually eliminated.
I guess this raises the question of why the bike from BMW didn’t ride like this in the first place?
Kudos to BoosterPlug as you can add me to the list of satisfied customers!
Gordon, 2001 BMW R1200C
Just received the Booster Plug for my R1200C.
Installation took a bit longer than expected. It was my first time wrenching on this bike so I was learning as I was going.
It fit in very nicely and I got the probe out front of the fuel tank in the fresh air. Good length on the probe wire.
The Booster Plug did its magic. Better idle. Better throttle response from a stop. Smoother running motor, more power and smoother transition from on throttle to off throttle.
The sum total of all of these subtle changes is a huge increase in performance.
A great product and very prompt, personable service.
Mac, 1999 BMW R1100R
I fitted the BoosterPlug yesterday ... less than five minutes work - dead easy - and I CANNOT BELIEVE the difference!
My 1999 BMW R1100R now feels and rides like an entirely different (= much, much better!) motorcycle.
Anyone can claim anything ... but you have come up with the goods brother, so well done and thank you!
I only wish I had found out about this earlier ...
Marx, 2007 BMW R1200RT
Just fitted the booster plug to my 07 R1200RT.
WOW. Truly transformed my bike.
No more scary roundabouts, or cutting out at low revs. Town riding as its supposed to be, not lumpy like it was.
Ive yet to try it on the motorway, but I dont think that will be a problem. (shows how pleased I am by writing a review before a full test).
Thanx guys, looks like im keeping my bike for a good while longer now.
Mike, 2001 BMW F650GS
Just bought a 2001 BMW F650GS and was not happy at all with the surging issues it was infamous for! I am a happy man now.
Got my booster yesterday, installed it today in minutes!
Bike runs smooth idle to top end of 5th gear. What a blast to ride a "new" bike for $150. Thanks guys!
Michael, 2002 BMW R1150R Adventure
I just installed a booster plug on my 02 R1150RA.
I love it. The bike starts easier and runs smoother than ever. No more surging.
If you get caught without down shifting when you should have, it pulls thru smoother than before.
Overall power? I see an increase but at different points. Pulled onto the freeway in fourth rolled it on, two upclicks, well into triple digits quickly.
Before installing I had read a comment about smoother shifting. Failed to see the connection. I get it now. Smoother throttle coordination.
Improvements were well worth the money.
Brett, 2002 BMW K1200LT
I received my boosterplug for my K1200LT 2 weeks ago and fitted it straight away.
Well the differance is very pronounced, zero throtal lag, more responsive at low speed,it has made my LT a delite to ride at city speeds.
Thanks for making such a great peice of kit for my Beemer.
Simon, 2006 BMW F800S
I just wanted to give some feedback after installing boosterplug on the bike and riding it this afternoon.
I tried to be as objective as possible and went for a spin before fitting.
As others have said, the engine seems to like the richer mixture. Right away the engine sounds noticeably quieter and less rattley at idle but the biggest difference is low speed throttle control.
Slow, careful filtering through stationary traffic always meant riding the clutch as first gear leapt forward too much, but that has disappeared after fitting the plug and slow speed in first gear is smooth and predictable.
It's like a different bike. I am very happy with it and will spread the word.
Jim, 2002 BMW R1150RT
I received my Booster Plug last Wednesday, installed it on Thursday and left on an 800+ mile trip Friday.
Not only was the installation as simple as advertised, the change in my R 1150 RT was phenomenal.
No longer sluggish at low speed with surge issues in between, the bike performed like a new machine.
Thank you so much for creating and supplying such a wonderful product.
Very few times have I been so satisfied with an aftermarket product.
Jerry, 1998 BMW R1100RT
Just wanted to let you know i received the Booster Plug today, and I installed it in about 10 minutes.
I fired up the bike and it was noticeable smother at idle. I went for a short ride and it was amazingly much smother at lower rpm in a higher gear than i would have normally chose at that speed.
The popping in my aftermarket exhaust is gone.
Can't thank you enough for a great well made product that works right out of the boxes advertised.
One last thing your shipment and deliver time is stunning.
Luca, 2008 BMW R1200GS
I have just installed the booster plug on my GS and it is AWESOME!
It really is good, my bike runs much better than before.
I had been looking for a way to improve the air/fuel mix in the cylinders for age with no luck.
I wish I came across your magic little thing a couple of years ago!
Well done. You did a fantastic job.
Barry, 2009 BMW F800GS
I fitted the Booster Plug to my F800GS and it has transformed the bike. (for the better , you'll be pleased to hear).
So much so that I have decided NOT to sell the bike which I found really unpleasantly jerky on the throttle before I fitted your magic bit of kit.
It is (as we say here) "the dog's bollocks"!
Dane, 2005 BMW K1200S
I installed my Booster Plug on my 2005 K1200S.
So I got to ride this morning to work and then back. I live at 8300', ride through 9000' and then back down to 7200' through great mountainous terrain, 25 miles each way.
Anyway... I am DELIGHTED! I ride almost two miles on a forest road on hard pack dirt before connecting to the highway, slow and easy. It was brutal BEFORE the plug, now it is smooth, the bucking-jerking-unhappiness of the engine is almost completely gone.
The roll-on throttle response is smoother, more responsive than it has ever been at this elevation as well as the deceleration...not near as abrupt from high speed. I motored in town (Los Alamos) a bit, 35mph, low and slow as they say.... smooth!!!
I can easily shift to one higher gear at this speed, no problem! I love this thing! Great job! Thank You!
John, 2006 BMW HP2 Enduro
I got and installed the boosterplug and I had to write and say thank you!
The plug made a significant positive improvement for my bike.
I have an HP2E and it has an Akra on it and has always run lean,.
Your booster plug fixed this problem and now my bike is perfect.
Thanks again for a great product and service.
Iain, 2010 BMW F650GS Twin Cylinder
Booster plug has been on the GS for a while now and I've been able do quite a few kilometres with the plug fitted.
The Plug appears to be more effective than the Acc Module (Competitor device) at lower revs.
The bike appears to pull smoothly down to below 2000 - I only noticed this when I became aware of some chain snatch, and noticed how low the revs were. This has never happened before because the engine wasn't as smooth at those low revs previously, so I would always change gears earlier and keep the revs higher. Now I have to watch the tach more at low speed or it is easy to lug the engine.
The bike also seems stronger at idle and will trundle along at idle in first gear without touching clutch or throttle. I'm sure this wasn't possible with the standard engine, or with the Acc Module.
Roll on acceleration in higher gears at higher speeds is much better than the standard engine.
No detectable change to fuel consumption - this bike regularly consumes less than 4.0L per 100 Ks.
Thomas, 2000 BMW R1100S
I do my own maintenance, but don't want the hassle of a custom fuel-map setup because my bike runs well stock.
However, I've always felt that the bike felt fuel-starved in many situations. I've been riding all sorts of bikes for years and I know what "lean" feels like.
Long story short: I love your product. I think you absolutely nailed the fuel map for a "regular rider" like me. My bike is even more enjoyable than before.
This is a great product and you have a faithful customer.
Thanks for taking the time to develop it, and to use high-quality materials, and most importantly, to offer it for a reasonable cost.
Dean, 2009 BMW HP2 Sport
I installed a Booster Plug in my 2009 HP2 Sport and am very happy with the results. The low speed, part throttle snatch was greatly reduced and many of the bumps in the roll-on power curve are gone. I have no idea if the fuel mileage was impacted and I don't care! The bike is much more fun to ride and I could care less about fuel economy.
John, 2004 BMW R1200C
I installed the Booster Plug on my 2004 BMW R1200C Montauk. I started the bike and left the garage. I noticed the difference within 100 yards. This product is unbelievable! Smoother idle, smoother throttle response, easier cruising at lower speeds. Overall improvement in all ranges. Easy to install and instant gratification.
Thanks so much.
Nick, 1999 BMW R1100R
I bought my 1999 BMW R1100r just over a year ago with only 3k miles on it. It ran great and was very smooth, but a little something was definitely lacking in overall drivability. If like my other bikes it had had carburetors, I would have re-jetted for a slightly richer mixture. Being fuel injected, that wasn't so easy, so I decided to just ride it as it was, last Summer and Fall, and keep an eye on the options available. I saw the Booster Plug on eBay this spring and it seemed to be just what I was looking for, so I took the plunge.
The Booster Plug was very easy to fit on my R1100r and looks a quality unit, so it blends in with the existing wiring etc. I fitted the temperature sensor using rubber grommets to the air box end of the snorkel.
As soon as I started the bike I could tell the mixture was richer, many years of carburetor tuning has given me an ear for such things, it no longer had that weak asthmatic sound that it made originally. As soon as I rode off I could feel it was smoother and torquier than before.
In traffic, I found I was generally in a higher gear and using less throttle opening while keeping up with the pace of the traffic.
On the open road, the torquier feel and all over smoothness is a definite improvement over stock. I don't have any way to measure if the bike is faster, it was pretty quick before, but the motor is certainly even more flexible than before and roll on acceleration in 5th is addictive. Accelerating out of corners is even more pleasurable and the motor responds better when blipping the throttle on down shifts. The throttle is much more linear.
Now to gas mileage. I have checked it twice. Today I rode probably 50 miles freeway 80 mph cruising, 10-15 miles in traffic some stop start, and about 10 miles on twistier roads. Filled up and my mileage was 51 mpg. I'd done a previous check after riding manly at lower speed with some traffic previously and this gave 55 mpg. It seems that I'm getting 2-4 mpg better than before. I believe this is because smaller throttle openings are used and often a higher gear to make the same progress, thereby making better use of the fuel. If I were to get on the open road and push it to the limits then given the richer mixture I may see a slight reduction in gas mileage, but then again may not, because an overly weak mixture can waste fuel also.
I checked my plugs that I'd cleaned prior to fitting the BP and it was nice to see some light brown color on them rather than what to me was the overly white appearance I was getting before. I think the BP will help keep the internal engine temperatures down too, something that was of concern to me with the lean stock fuelling.
All in all the product does what is claimed and has made my bike much more satisfying to ride. I never really suffered with the surging that some complain of, but the bike is much easier to ride smoothly now, before I was definitely riding around some of it's shortcomings. Based on my experience I would highly recommend this product.
Simon, 2007 BMW K1200S
I fitted my Booster plug yesterday and took my bike to BMW for a service during which they updated the software to the latest version. I collected the bike today and I can tell you this:
My K1200S is totally transformed into the amazing machine is should have been when it left the factory! The low end surging and bucking has almost totally disappeared. If I wasn't looking at the bike as I ride it, I would sware it's a completely different model.
It was getting to the point where I was seriously contemplating exchaning it for a newer, different bike which could have cost me thousands of pounds. But for less than £100 pounds, I now have the bike that I always wanted, I am delighted. Thanks Jens, thanks Booster Plug.
Blaine, 2010 BMW R1200RT
I've got a 2010 R1200RT, and the boosterplug made a very noticeable difference in how the bike handles and feels.
It used to gag and gasp and stop running upon being started, first thing in the morning, now it fires up with enthusiasm!
Throttle control now doesn't require the dexterity of a neurosurgeon to twitch it open and closed at low speeds.
Acceleration is smoother too.
I was prepared to be a skeptic, but tens seconds after starting the bike up, I was a convert!
Simon, 1998 BMW R1100GS
Hi Jens, I have been riding with the BoosterPlug for a couple of weeks now and I have to say you have hit the nail on the head. The performance increase isn’t blistering like a turbo but it has added a new dimension to my GS 1100. The torque increase is very noticeable with the bike using less revs to maintain its speed, acceleration is very exciting and most noticeable of all the ridability of the bike is completely different.
It behaves much more predictably, applies its power precisely, pulls from low revs and winds out more efficiently, and all the time behaves like a compliant wild animal. The booster plug has let the GS become the bike it should be. Fuel efficiency has dropped about 1km per litre but that may be because I am so keen to open the throttle.
My only disappointment is that you included such a small sticker??? People should know about your product, I love what it has achieved form my bike.
And by the way, the extreme temperature ranges that occur in Australia require well thought out solutions so your external temperature probe gives me the confidence that my bike will adjust itself to these extreme conditions and remain reliable.
Thank you for your expertise and insight into providing a truly great plug-and-play modification. PS, it took longer to undo the box it came in than to fit it on the bike.
The text below contains Simon's follow up after 12 months of heavy use.
Well just to let you know that having the booster plug plugged in for a year (28,000 kms) and going through the range of temperatures and weather patterns we have had in Australia it has continued to perform faultlessly. I have done a number of alpine treks on and off road and many 7-12hour overland trips, mostly at night. There is a consistent surety in power delivery and the fuel consumption has not changed since it was first installed. As the weather cools off the booster plug shows a greater difference from the standard settings and the GS feels a lot more aggressive (pleasantly so). Many thanks yet again and congratulations on such a great plug-n-play modification.
Steve, 2006 BMW F650GS Dakar
I've had your wonderful device on my bike for a few weeks now and can only say how happy I am with my decision to purchase the boosterplug.
My F650GS runs so much better in all weather conditions from low 30's to upper 90's that I just can't believe it!
It's a very responsive bike now and the power-curve is so much more where I like it to be.
Even on the highways I haven't had any trouble with it.
Thank you so much!
Chris, 2000 BMW R1100RT
I installed the booster plug on my 2000 BMW R1100RT. I was using the R259 Techlusion box for the last several years.
I was really hesitating removing the R259 as it seems to really be great except it I could never achieve a real smooth perfect pop free low idle.
I read your explanation and it made perfect sense on how you designed the plug.
Well, I have to say it is super smooth now and I am impressed just how much better it runs as well.
The idle is great even cold and I do not need nearly as much choke during start up as before.
The fuel mileage so far seems unaffected as well with well over 300 miles per tank as usual.
So again thanks for the better mousetrap! I would highly recommend this to everyone. I only wish everyone products would perform as well.
Gavin, 2008 BMW G650 Xcountry
I received the Booster Plug very fast in the mail, thank you.
First off, the quality of construction is top notch and it is was very easy to install.
I installed it last night and test rode the bike today. Does it work? Let's just say that when I whacked the throttle in first gear...the front wheel came off the ground! It didn't do that before and it does seem to idle stronger, smoother, etc.
So yeah, it works, and I am a happy customer and looking forward to riding more this weekend.
Sharil, 2006 BMW K1200S
Installed the BoosterPlug last week on my 2006 K1200S.
Got this bike a few months back from a guy who actually parked his bike in his bedroom! Only got 6000KM on the clock, when I took over, and although a good bike, got some niggling issues especially at low rpm.
As soon as installation completed, I went for a ride. Everything is just like you claimed! Excellent improvements with a small investment! Feels like bike just been to a dyno-tuning. No need to grapple with the clutch at low speeds. Will definitely recommend to my friends. In fact, I asked my regular workshop guys to contact you and stock these in Singapore. The BMW bike community will love this.
Thanks and regards.
Gerhard, 2009 BMW F800GS
Hello Jens, I bought your Boosterplug before Christmas for my 2009 BMW F 800 GS. Today the forst ride…and WOW. I never thought,the difference is so big. Very well done, Jens. Now a few sentences for your german clients:
Nach dem 2. Oder 3.Update der Bordelektronik dachte ich zuerst, den BP brauchts nicht mehr…… Weit gefehlt: mit BP ein deutlich verbessertes Langsamfahrverhalten,viel weicher an´s Gas;Landstraße, Gas auf,Gas zu bei vielen Kurven ein völlig neues Vergnügen. Absolut empfehlenswert für die F – Baureihe
Many greetings from Bavaria
Randy, 2007 BMW F800ST
Received the BoosterPlug for my 2007 F800ST, installed it today, and went for a ride. It was very easy to tell that opening the throttle no longer took a few seconds for higher power to come on; all available power for any engine speed was available immediately when opening the throttle, and the power built cleanly and smoothly as engine speed increased. Thanks for producing such a simple but well engineered an well built performance improvement.
Ara, 2007 BMW R1200GS Adventure
I finally got to install and try out the boosterplug. Took a while because I had sent my rear damper for a rebuild. The wait was torture. Now the verdict: Excellent!!!!! I want to congratulate you on a job very well done. Thank you for bringing my engine to life and making me enjoy my bike so much more. You really solved the problems I hated about the engine. Idle feels stronger. Now I can slowly release the clutch from standstill and have the bike rolling without touching the throttle. I could hardly do that before. Its much smoother at low RPM and the pickup is much better without the feeling that the engine is stuttering and going to die on you, especially if your rolling close to idle in 3rd gear and want to accelerate. The flat spot in mid rpm is almost gone. And you feel that the engine accelerates much better than before. All in all a great improvement and MUST have product.
David, 2003 BMW F650CS (Scarver)
I have to tell you that I installed my Booster Plug on my F650 CS (Scarver) last week. I could feel the improvement before I had covered the first kilometre!
There is a hill close to home, (one of those long ones with a reasonably tight bend at the bottom) that I always had to change down for. I can now accelerate all the way up this hill in top gear. I am absolutely amazed at the smoothness, and I can now pull away smoothly from 1000rpm lower than before.
Best value for money I have ever had!
John, 2007 BMW R1200RT
I was happy to receive my Booster Plug Mk2 here in Florida five business days after I placed my order. The Booster Plug was simple to install on my 2007 R1200RT, and it has improved overall ride-ability beyond my expectations. Throttle response is smooth and predictable. The Booster Plug works just as advertised, and it's a great value. I am now an official Booster Plug advocate. The Booster Plug should be every new BMW owner's first accessory. Thank you for creating such an elegant and affordable solution to the ride-ability issues that are otherwise unavoidably associated with the modern lean-buring, fuel-injected motorcycle engine.
Dave, 2009 BMW F800GS
I installed the BoosterPlug and had the opportunity evaluate it this week. Hey....it works!
The open to close throttle transitions are considerably smoother. In addition to it being more pleasurable on-road, it really helped during the technical off-road maneuvers where throttle control/smoothness is required.
You should be sure to elaborate this point further on your webpage. The off-roaders will truly appreciate this benefit.
Frank, 2006 BMW R1200RT
I installed the Boosterplug this morning on my R12RT.
The bike is fun to ride again thanks to you.
I have been trying to get the idle fluctuation and stalling fixed for almost 2 years.
Your device solved the problem in minutes.
I sincerely thank you.
John, 2008 BMW R1200R
I've finally found time to say thank you to you for rescuing my bike!
Between the standard screen being too small and a lean running engine causing vibration at 130kph on a long summer trip to Croatia from Scotland, I was on the point of selling and doing something else. An MRA screen has fixed the wind blast noise and your plug has made a big difference to the running of the engine.
The bike now runs cleanly and pulls from 1500rpm and is way smoother at all revs. I'm finding that it runs smoothly 1 gear higher everywhere and sometimes 2. Where 4th gear was needed at 50kph, it's now 5th and even 6th on a light throttle. The pick-up is better from any revs as well. It pulls hard and smoothly in a high gear and once up to speed, the motor feels much more relaxed as it's so much smoother.
Overall, it makes me sink into the bike, relax and enjoy the big engine. And when back home, get the maps out to plan the next trip.....
Thank you very much for your time and care in developing the booster plug - it really works well and makes the bike as enjoyable as it should be as it leaves the factory.
Greg, 2009 BMW F800GS
I just wanted to let you know that I am very happy with the Booster Plug on my F800GS.
This thing has returned the essential throttle control that every dual sport motorbike needs. No longer does the bike jump out from underneath me or try and toss me over the bars like an untamed horse.
After two months of use on and off road, I can happily report that my fuel economy is still above 50MPH.
Thank you for making my bike a joy to ride!
Guy, 2006 BMW K1200R
I put in the BoosterPlug last night. The difference it has made is astonishing!
There’s still a very small amount of snatch at low revs but nothing like the bucking and jumping before.
Previously, with a hot engine, I couldn’t let the revs drop below about 2,500 – 3,000 without the snatch becoming so annoying I would just pull the clutch in and glide; now I can let the revs get down to just above idle in any gear and the pickup when I engage the throttle is smooth.
I only used the k1200r for fast runs before because of its poor handling at low speed. I guess I can use it about town now!
Mike, BMW R1100S
Well I got my boosterplug fitted last week but just didn't get the chance to ride the bike until today.
I can pretty much sum it up in one word WOW!
When I fitted an "accelerator cable" (Competitor device) it made my bike feel 100% better for about 70% of the time. Unfortunately there were times when I could tell it just wasn't happy. Usually when the engine was good and hot and you got yourself stuck in heavy traffic. When I read your comments on your web site it all made sense. I was under the impression that the "accelerator cable" gave the engine an extra 6% of fuel all the time.
After I had read your comments it was easy to work out what was causing my engine to be "unhappy" in heavy traffic. The air temp on a hot day with an hot engine must have got quite high under the bodywork. The accelerator cable in those conditions must have given the engine an even higher % of fuel.
I knew after reading this that I had to invest in a BoosterPlug. I really don't know what I was expecting it to do but all I can say is, my bike runs 100% better 100% of the time. The bike feels a lot better, not just in traffic where it now behaves itself totally. But also in normal riding conditions. It feels so smooth it's like a totally different bike.
I bought my R1100S without ever riding a BMW before, I was really disappointed and was on the verge of selling it. What I really didn't like was the way it nearly stopped when you closed the throttle, it felt like you had turned of the ignition switch.
Not any more, shut the throttle and it slows down gradually, making for a much smother ride.
Top notch product.
Scott, 2007 BMW F800S
Jens, I installed your Booster Plug last Friday and wanted to give you a testmonial for anyone to reference. It took me no more than twenty minutes to install on my 2007 F800S and have put about 500 miles on the bike since. By far the biggest difference I noticed right away was the newly found silky smooth shifting. There is no hesitation and much less clunking when shifing gears and a much more enjoyable ride. Your product has completely tranformed the bike into a smooth running machine. Your product does exactly as advertised, which means no more fear of stalling under low RPM’s for me. I even tested dumping the clutch around a parking lot thinking it would stall, it never did! I continued to attempt this up a hill with my girlfriend on the back, no stalls! Gas mileage is slightly affected, but not by any signatficant amount. A small price to pay for an smooth running, shifting and overall more positive experience into my daily riding routine. Great product
Andrew, 2007 BMW R1200GS with Remus Powercone exhaust.
Fitted Jens Booster Plug today and I’ve been out and about for a quick ride, staying mainly in town because as this is where you really notice the bike is transformed and it’s now a pleasure to bumble in town traffic. Gone is the feeling the engine could falter if you don’t keep the revs up when manoeuvring at low speed. As soon you feed the clutch in the engine feels stronger, this gives you confidence, consequently you’re not revving the engine so hard when clutching, you find yourself changing up earlier and trickling in a higher gear without any surging, pick up from low revs is smooth and more controlled.

I have ridden the bike for the last 3 days.
The BoosterPlug has made a big difference in throttle response smoothness. I had a PowerFRK (Competitor device) on the bike since October 2008.
The BoosterPlug is a BIG improvement.

My first ride with BoosterPlug. Great; doing all the stuff Jens claims. Smoother throttle response, no jerks, acceleration may be quicker and at start-up fired immediately, no turning over 2 to 4 seconds before running.
I am sold. If you do not have a BoosterPlug get one.

I installed mine yesterday on my '09 GSA. Install took about 10 minutes. Very easy. My temp probe routes along side the left of the tank, over the fuel pump lines and then is zip tied to the left of the forks in open air. I can see it when I am riding but you can't see it if you are off the bike. I did about a 20 mile test ride. Outside temp was about 40 degrees. Things have smoothed out at lower speeds. Added a good amount of low end grunt. Wide open acceleration from 1st through 3rd seems greatly improved. This may be in my head but it actually seems to idle better. I am very happy with the product. Some much that I have ordered two more of them for my other bikes.
Great job and product Jens!

Received my BoosterPlug last week and fitted it straight away. It does make the bike smoother on gear changes and low speed work along with giving it better acceleration. Thanks for a good product

Well what do you know, it works ! It took a few minutes to fit and a short ride to confirm all your claims for the product. The throttle response and fuelling is greatly improved with little or no snatch. My previous bikes have been several BMWs Honda Blackbird VFR R1 Fazer 1000. All but the R1 were snatch and would have benefitted from the Booster Plug. My bike is now a real delight to ride. Well done Jens.

I installed my Booster Plug yesterday. Noticeably smoother on/off throttle response. It seems to pull better from low rpms too.

2 days of riding with the Boosterplug installed on my 05 650 Dakar was similar to others comments. Smoother roll on / roll off on the throttle, less snatch and shove response to throttle input which has always annoyed me about this bike. Much easier to ride smoothly which has got to be good for the engine / clutch etc. Very easy 5 minute install.

I purchased the "booster plug" two weeks ago. I did not like the jerky throttle respose as well as what power steps when accellerating, with the factory set up. Assessment: I has most assuredly smoothed out the throttle response. The accelleration is smooth from off idle to 6 grand and above. Am I satisfied with my purchase, YES! One feature I like, is there was no modification to the bike's wiring. Everything can go back stock in less than 20 minutes. Would I recommend it, YES! I find it made the R12R more rideable, more enjoyable at all speeds.

Hi Jens - I just wanted to give you an update on the BoosterPlug, it only needs 1 word, Fantastic !!
I fitted it 2 weeks ago when it arrived and I've now done 240 km on all kinds of roads. The bike is transformed, it's more like a 4 cylinder engine now rather than a big twin. The pick up from a closed throttle is just so much smoother without any of the sudden snatchiness that was there before.
Riding around town at 2000-2200 rpm is actually possible now in 2nd or 3rd gear, the bike feels totally smooth and refined. Previously I either had to use 1st a lot which made it rev a bit and also made the throttle response really sharp or just try to ride around the lurchiness in 2nd and 3rd. It's also a lot nicer on roundabouts when I'am rolling on and off the throttle as the bike just picks up smoothly and drives, definitely gives you alot more confidence when cranked over in wet and slippery conditions.
Once I'am accerating hard I don't notice so much difference except that the bike seems a bit stronger around 4-5000rpm. I wasn't looking for race track performance so this is perfect for me. Fuel consumption seems pretty much identical, previously I used to average around 52 miles per gallon, on the 240 km so far it's worked out at 50.7, the same thing in my book.
It's been a total success in every respect for me :-)
Your website is brilliant with clear explanations and no crazy claims
You delivered the BoosterPlug when you said you would, actually even a bit before It works exactly as you explained that it would
So one very happy customer and I'll definitely be recommending the BoosterPlug to anybody that asks.
Mike, 2007 BMW F800S
Bike is transformed - it's low speed 1st gear performance is turbine smooth, clutching out on level surface in 1st with NO throttle just came naturally - I didn't even have to think to consciously try it.
Idle, especially right after a cold start, is smooth as silk, no missing or hunting.
Now...... it's not that the F800s was BAD to start with; a little snatchy, tiny bit uncertain matching RPM with speed esp. on 1st - 2nd upshift.
This is a fantastic product!
Randy, 2007 BMW F800ST
Received the BoosterPlug, installed it today, and went for a ride.
It was very easy to tell that opening the throttle nolonger took a few seconds for higher power to come on; all available power for any engine speed was available immediately when opening the throttle, and the power built cleanly and smoothly as engine speed increased.
Thanks for producing such a simple but well engineered an well built performance improvement.
Michael, 2007 BMW K1200S
After my first hundred miles with the BP installed I'm very happy.
The bike runs great at all rpm's and no more flat spots.
All of my throttle transitions were seamless and smooth as silk !
This is the way I expected this bike to run from the factory !
NO Jens, I'm not giving it back ! I'm a very happy customer !
