I have been searching thru the forum on this issue, but all I seem to find is the issue with the small oil drip. My issue is basically oil puking out of the air filter, enough to coat the side of the bike and my leg. Been trying to figure out this issue for a couple weeks now. The bike is not over filled with oil, I have replaced both breather valves / gaskets in the head. Not sure what to do next. Anybody have any ideas?
