It would take something pretty noticeable. Dang on the 85mph for 2 hours! I have no experience on these bikes doing that! That might be the culprit, but that still seems like a lot of oil consumption. Good luck. I’m outta ideas. Maybe somebody else with more experience with these bikes can weigh in.
Nah, I don't think there were any major flooding, if any, I think it may be just running the engine under high stress for a prolonged time. I know this bike isn't made for high speeds, but man it keeps up like a champ, and I'm having way more fun on it than the Harley guys have on theirs - they are just cruising their large displacement bikes at that speed, while mine feels like racing.
But I'm a bit worried about the consumption, because in the past I have ran it at WOT for 30-50ish mile distances, and ran it hard in the twisties with the sport bike riders, but it never consumed any oil. I wonder if mineral oil is more prone to consumption.
Now that I am thinking about it, I do smell burnt oil occasionally, and burn mineral oil has this very specific smell that reminds me of sunflower oil when its burning. Synthetic doesn't have this smell when it burns.
