Yamaha 660 Series

 
The Yamaha 660 cc singles are extremely versatile bikes, capable of going anywhere - on any kind of roads.
Unfortunately, they are let down a bit by the extremely lean air/fuel mixture provided on the stock bike, and the result is an engine that stalls easily and a hard unpleasant throttle action that makes difficult sections and city traffic harder to negotiate than necessary.
The BoosterPlug will provide the small controlled fuel enrichment your bike need to behave like it should have done from the factory.

"The BoosterPlug is a brilliant Power Commander alternative"  
 


A Power Commander is a great tool, but very expensive because you need lots of Dyno hours to set it up correctly - and due to the (too) many parameters to adjust,most of them never are. The BoosterPlug provides a proven and efficient solution in a plug and play package, with no need for eternal adjustments.
