Fred, do you know if your running the stock Honda clutch springs? If you are I would recommend running titanium spring, the Honda springs are an okay back up if any break but they’re often not stiff enough to overcome the forces at high speed.
Shaun, I saw your comment above saying that you usually get 3-4 hours of piston life, I can get at least 1 or 2 solid seasons (50+ hours) out of a cr85 piston, with minimum to moderate over-rev. How long is your track and your races, and if you know, what is your water temp during races/practice?
