This may sound unrelated, but my newist Harley motor Has a major oil blowing problem on the rear clyinder. I racked my mind trying to come up with a solution, rings, intake guides, popped wrist pin clips, ? What I found upon tear down was the oil ring had collapsed causing it to suck oil like mad. Now I have seen it on auto engines and lawnmower engines. It may have been an assy mistake or a bad oil ring, but I have a new set of rings and it should correct the problem. Just food for thought.
