Engine Squeak

I was headed home last night when I noticed a decent loss in power and some intermittent squeaking from what sounded like the top end of the motor. Once I got home, it gave a lot of resistance trying to kick it over and I had no luck starting it. I've got fresh oil, a new filter, new tires, chain and sprockets on there, and this was the first day I'd done any long distance since the new stuff.



It seems like I need to replace my float needle and seat, so I thought that might've been the loss of power until the squeaking came about. I think the flywheel might've been turned clockwise a bit while the cover was off for sprockets, but would this affect timing while the cam chain is still on?



A friend thought the valves sounded kinda loud, but it's a loud bike to begin with, as far as valves go. I've also heard something about carb resistance and the slide squeaking or something like that, but I wouldn't think that could cause enough resistance to keep from kicking over unless something was terribly wrong.



I'm gonna hopefully get the valve covers off and look for anything odd and set clearance tomorrow, but school's keeping me busy. I sure hope I haven't wrecked a valve, or worse, the cam. Any ideas what it might've been?



P.S. I can't remember if I'll need my straight feeler gauges or the angled ones. Anybody know?
