This is SO important ! When you buy these individual shims, you can get the "in between" sizes to get your clearances exactly where you want. Shim kits only have the full sizes, and the adjustments are too big. No more kits for me. I will buy the individual shims I want rather than sit with dozens of shims I will never use......and many times still don't have the half-sizes I need.Read All Reviews

These valves are great. When I rebuilt my bike I redid my head (cut the valve seats) and then installed these Pro-X steel exhaust and intake valve kits with new seals. Bike started in 2 kicks and has been going strong since. It's been about 3 months and I've been racing nonstop since then with no problems. Still starts in about 2 kicks, and I haven't even had to re-shim them.Read All Reviews
