Blowing oil

[steve tysinger]

Been having an issue with oil blowing out of the crankcase breather tube.

Compression is good. My mechanic is having difficulty in diagnosing the problem.

The problem is greater when you gas it more; if you just put around not much comes out.

Thanks...

Yes we double checked the oil tank level. It's a "BIG" problem. Blowing a lot of oil. Runs great, plenty of power.

is it using oil might be just overfull if its using and blowing got to be rings?plugged case filter?

Have you checked the plugs for oil fouling?

Scope the cylinders and look for a broken or burnt top ring land.

Check oil pressure. If bypass is stuck closed more oil than normal whipped around in crankcase.

IS there a crankcase vent tube somewhere....on other bikes they may get clogged, and the oil and vapors have to go somewhere else...usually in the manner described by the OP.
