That's one fo the most usefull things I've acquired lately for my mx. For the price, 85$ in a box of 141 shims 8$ each at the dealer, they are a huge time saver for those who adjuts their valves and are forced to get one shim at a dealer (supposing the shim is of the correct size).

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.

I have been using these for over 90hr and they are still holding strong. Always my first choice for valves. I like the coated valve stem for added life
