Hi there. I have a 2003 1200S, and a strange question. I noticed what looks to be a grease nipple on the side of my bike. I can'd find anything on it in the owners manual. There is a circular case, about 2 inches in diameter, on the left side of the motor. It is bebind the actual engine, above about where the front sprocket is. It has what seems to be a grease nipple on the top of it , covered with a small rubber cap. Can't find anything about lubrication there. Don't want to seem like a complete fool at the dealer. Any help would be appreciated.
