Great Valves

Loran in Alaska – Machine this part was bought for: 2007 YAMAHA YZ250F

Comments On Jun 11, 2013: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.
