Hello, I have been trying to diagnose rough start, idle and restart issues for some time now. I bought the bike a month ago, am unsure of the previous owners hours, and have put 1hr on it in the times I've gone around the neighborhood. I just took a look at my valve clearances and found this: Missing camshaft cap bolt (exhaust) 1 exhaust valve pretty tight Valve clearances: My timing seems to be off, if I'm not missing something. I was going to remove the caps, reset the timing and remedy the tight clearance, but wanted to make sure I am being thorough enough now that I saw the missing bolt...possible damage? Is it common for just one exhaust valve to be so tight?
