  • Faction MX Exhaust Valves

    Excellent valve set!

    Bought these on a budget figuring I would swap them out for titanium later but they have been working so well they're staying in. They don't seem to bother the high end rev and are very reliable.

    lots of shims

    I found a simular storage case at kmart for 4 dollars and wish I would have just ordered a hand full of shims. Way to many and I will never use them except for a few.

    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.

  • Pro X Steel Exhaust Valve/Spring Kit

    Pro X Steel Exhaust Valve/Spring Kit

    Loran in Alaska

    Great Valves

    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.
