Carb Mods: for the power where you want it!
From trail riding to the race track these great carb performance modifications are designed to help address many of the tuning and
ride-ability issues that seem to be inherent to many of the two strokes bikes of today. Our goal is to give you that low end performance
that you need and want, along with great throttle response right through a stellar top end.
Our precision machined and contoured Divider-Plates
are permanently installed into the carb bore and it does not reduce the carb bore diameter in any way. Trail and Race Track Proven!
Note! This is not a carb cleaning service, our carb modifications are precision preformance enhancements and are done to known to be good carbs off running engines. Carbs must be sent in clean condition, debris and gas free. Remove all hoses (do not send) and make sure to send your slide with carb to be modified. We always return any of your unused jets and parts.
