I changed the air filters and did a carb sync on the Venture today getting ready for a trip down the Natchez Trace tomorrow. While I had it sitting level, I checked the oil level, and it was dead center of the sight glass. And I have not seen any more oil on the under the bike. So MAYBE, I was wrong about the oil coming from the bike. It could have been some oily drippage from the washing we gave it. I'll keep a close watch one it and see how it goes.
