Also the reed valve on the carb side they just wear out. but i dont think i would be that drastic more like loss in hp. And lastly is a toasted ring. Everything is still spinning but maybe you lost compreesion and not getting the bang for you buck. Another thing that i have seen is sometimes the case will leak and suck air and you can get all kinds of wacky stuff going on. If you can hold a smooth constant idle your case is most likey sealed. Things i would do check the power valve should be closed at idle or reall close to closed and check the reed valve were the carb connects they break down and become sloppy and could crumble if given enough time.
At least someone has some common sense.

Get this bike race tuned, THEN compare them. And bear in mind, this bike is a 80, not an 85.
