Could very well be valve clearance. Could also be a worn piston or if the valves were run too tight, you could have damage to your camshaft, rockers and sub-rockers. First thing to check would be valve clearance.
Sounds like it could be a maintainance issue to me. Or a lack of one. :nod:

it runs quiet when i first start it up only after i ride it hard and the motor heats up it doesnt lack power got lots of power ....well valve clearance check before next ride i guess ,must order clymer now only had bike 6 months maintance time i guess
Could be running lean, a jetting issue or timing. Check the plug.

I'm with Fox. Most times I've had noise problems after it warms up and not when it's cold, it has been jetting or timing.
I'd check valve clearance, timing, timing chain slack and clean the heck out of the carb and jets. Fresh gas and oil, too.

gets fresh gas everytime i ride and just changed oil and filter before last ride well going to shop :( this week some time i'll ask them to check that also.dont think its a jetting problem cause the bike is stock and runs and idles fine ....oh well tooo the shop till clymer comes :bang:
You are supposed to tell us if your bike now runs correctly. 8 hundredths of an inch is a lot! When they get too tight, they are not closing all the way. Sounds about what 89er said?
