Hi, Has anybody had Schmidt Bros do the Primary Clutch overdrive Machining to there clutch on there Nytro? Sounds like an inexpensive way to gain 3-4 MPH if it works. Looking for coments of anyone who has done this and their opinion if it does what they claim or any drawbacks to doing this. Thanks.
 
Poleclimber on here did it and said that it really worked had great topend I've been thinking about it myself it's worth the money...just have not had the time to get it done yet
 
What do they do? How much $$?
 
They machine the sheves so the belt will ride to the top of the clutch (primary clutch) which gives you more topend

Schmidt brothers racing does it
