Put bike back together, it doesn't want to start and when I first push start button, there is one loud clank, then starter motor just turns over. Bike does not start now. Engine was rotated off TDC as per instructions, before starting bike. Per this forum, the alternator bolt was rotated clockwise to achieve TDC. I reached up after aligning marks, the one valve that needed adjustment had a little play in it. It was out of spec, I tightened it up. Questions are: Was rotating the alternator bolt the correct thing to do? Is the fact that there was play in one tappet and I was able to measure the gap on the other three valves, would that indicate I was at TDC on the compression stroke? No adjustment was necessary on compression release. It would sure be nice to know what could have gone wrong before having to take it all apart and start over again.
Did you rotate the bolt at the port end of the crankshaft? If so, that one is supposed to be rotated
counter-clockwise (at least that is the case on my bike (see signature)). Rotating it clockwise
may have caused the cam chain to jump time. Something to keep in mind as you troubleshoot.
Having said that, I'd check the easy stuff first:
Battery fully charged?
Float bowl primed?
Gas in tank?
Gas tank lines connected (fuel line, vacuum line)?
Spark plug connected?
Report back with results, please.
Good luck!
