400ex burning oil
there is no "mechanic in a can" solution for worn rings. The best thing to do would be check compression, then add a teaspoon of engine oil into the spark plug hole and check compression again, if the reading comes up significanly, the rings are worn (seals better with the oil in the cylinder) if not, you have worn valve guides or valve seals. either way, you'd be taking the cam chain and cylinder head off, so doing a whole top end rebuild would be a good idea.
check compression with the choke off, throttle wide open, let the needle on the guage flick at least 4 times as a general rule. remember to disable the ignition.

Could it also be possible that sicne I'm not using the proper oil (I'm using 10W30 not 20W40 or whatever is best for ATVs), that the oil is too thin that it gets through the rings and burns?
Also, if I have to rebuild, how much does this cost? Would it be better to just go for a 416 kit as it should cost about the same?
