Last week i noticed a significant amount of oil under my '03 America after a 9 mile ride. Figured out it was coming from the airbox drain tube. Figured it was from the oil being overfilled when i bought the bike a year ago or from a tip over from awhile back and that it just took some time to leak out. I popped out the plastic plug and let it drain out. Just went for a ride and noticed more oil. The oil is warm. If i let the bike run the oil drips out faster. Oil level in sight glass looks normal. What could be causing this much oil to make its way to the air box drain tube? Thanks for any insight.
