Here's the deal...when mine happened, I assumed it was from wheelies. How else could it get that high up the wires.... but when I dropped the bike off to get all the probs fixed, my mechanic was already aware of the problem. Said he heard someone talking about it at a tech class he went to.
He said wheelies would speed the transfer of oil but would eventualy end up at the connector anyways. He described to me just how much preasure that crankcase makes in the 12. No PCV mod would cure it but it wouldn't hurt.
I know this guy is a good mechanic, but I also know they can bullshit their way through anything. I just had him go ahead and fix the problem with silicon. He even went a step further and put the kind that is fuel/oil proof. Other wise...regular silicon would break down after a short time. He also replaced the whole wiring harness, stator, and voltage regulator.
