Faction MX Exhaust Valves
Matt in CA
pretty good
These valves are good. can't say they are great because I can't really tell the difference. great money saver and w/ replacement valve springs and seals its great. I have an 05 CRF250R and I can tell that it wants to stay on the gear longer when I let off the gas. pretty good. good investment.

Pro X Valve Shim
Owen in WV
No more shim kits for me
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.
