For some reason the timing on my cams is off. I just replaced everything on my top end, piston, rings, valves, cylinder head...you get the picture. The bike now has about 3 hours since the rebuild incluiding an hour and a half hare scrambles. The bike was running a little sluggish today then refused to start. I pulled the cam cover off and the lobes on the cams did not line up when the piston was at top dead center, which ment the dimples weren't where they are supposed to line up on the head. What would be causing this? I could really use some insight on how to fix this issue. I'm almost completely over 4 strokes!!! HELP!!! thanks!
