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.

the springs are very good, no problems, they need to come with instructions, very happy.

I was burning about a quarter quart of oil every ride, I installed the Pro X Valve seals, as well as a new forged top end kit, no more oil burning, does the job, high quality part
