Re: Motor oil levels
My guess is that an extra quart would start to submerge the clutch basket and cause problems. I would think you would start getting crankshaft churning before that.
There was a guy a while back with clutch problems and his oil window was totally full even when the bike was on the side stand. So how overfilled? Who knows.
And of course he never posted up how overfilled it was or if the clutch problem was fixed.
