My oil was changed by the local H-D shop. They overfilled the tank to the top of the oil fill plug. Not knowing this, I rode the bike for a couple hundred miles before I realized it by seeing oil dripping out of my carb/air breather. If anybody has any ideas about what might have busted or how to fix this please let me know. When I tried to extract some of the oil from the tank, it smelled like it was full of gasoline.
