Well, I checked the valves 10 hours ago on my bike and they were perfectly in spec, then it would start anymore so i check them again. and the right intake was .002, left intake was .0015, left exhaust was .003 and right exhaust was .006. So I took the head off and the valves were sunk in a lot. Should i just try to re-shim it, or should i bite the bullet and send it in the get my head machined??
