    YZ250F valves to tight?

    Thanks KJ. The exhaust slides in firm, I can actually get a .018 in if I wiggle it in. The intake will take a .008 easily, (I don't have a .009) but the .010 is very hard to get in. It will go with some effort. Change the intake only, or should I change both?

    YZ250F valves to tight?

    Are the valves in my yz250f to tight? I can get the mimimun guage in for both intake (.10) and exhaust (.17) but both are tight to slide in. Do I need to change the shims yet? Also, I would have thought that the gap would get bigger with wear, not smaller. Is this normal?
