I reassembled the clutches and primsry case. Rollers looked good. Just the slightest flat spot on a few of them. Belt was good. When i ran it open the front clutch never seemed to expand but i think its bc the motor didnt spin fast enough to engage it. With everything except the plastics back on it starts and idles fine but with full throttle barely moves the wheels on jack stands. All gaskets are new. Compression is great. Only thing odd i noticed is motor doesnt sound completely normal and the air temp out of the top end case seems hotter than usual. Im thinking about rebuiling the top end again even though its new. Thought ring clearance was good but maybe its too tight?? Might try a new plug too. What's the best plug to use here??

Update. I removed exhaust which may or may not have made a difference. I opened primary case to inspect clutches. Front clutch looked ok but there was alot of grease in it. Cleaned a bit and reset rollers. Rear clutch seemed not to engage well. Spring wasnt extending fully it seemed I opened it and took the sheen off the contact points and reassembled. Belt looked ok. Ran with primary open and it seemed better but still not enough power to move the bike with weight on it. Still lost.

Pretty sure its a 2000.

I rebuilt the top end, rebuilt the carb, and replaced the reed. Starts, runs and idles but has no power. Cant barely move itself with no one on it. Air filter ok. Sounds like its bogged down with throttle open. Compression test showed 140 psi. Plug looks good. Gaskets look good. Im lost. Any suggestions??????
