[QUOTE="cleonard, post: 145513, member: 21"] A little blowing out at high revs and wide open throttle is not unusual on most bikes. However, it is also a symptom of worn rings that are not sealing. As more combustion gases leak past the rings they have no where to go but the out the breather. At some point the velocity out the breather gets high enough that it carries some oil. I can't imagine that your riding season lasts all that much longer up there. Pistons and rings have a short life in current bikes and even cranks are usually only good for a couple hundred hours. I'd say that you have an off season project. [/QUOTE]
