I've searched other threads but don't see a good answer. I removed the small canister and plumbed the crankcase vent directly to the air box. After every ride, when the bike is setting on the side stand, oil will drain out of the air box to the ground. I've checked the oil level on numerous occasions, exactly following the manual's procedure to the letter and it's never been too full. Of course, the harder ridden, the more oil comes out. I'm planning on re-installing the canister so maybe the oil will drain back into the crankcase. Just wanted to see if anyone else has seen this? My neighbor has the same bike and removed his as well but doesn't have the oil in the air box problem I do. He runs his as hard as I do mine, but he has no leakage.
