Right now I've got the engine apart, and am putting in new rings. When I' put the head back together one cam seems to roll freely like it should the other is really stiff as soon as I tighten the bolts on the cam bearing cap. Even just finger tight and cam is binding somewhere..... I have only taken the cam bearing caps, and the cam locating rings, and cams out in order to get the head and cylinder off....so I didn't touch the valves at all. So there isn't much to put back together and I can't see what I could have possibly done wrong.... Any ideas guys? Thanks, I hope this can be resolved quickly as we are leaving for a 6 day riding trip next week and I need my bike together soon!!!!
