Hi, I just bought a o1 vstar for dirt cheap the old owner had said he ran it low on oil and a clank noise is coming from the bike, around the oil pump. I am new to the street cruiser but have riddin motocross for years. The bike fires up and when reved the clank gets louder then idled down it quites down. I don't want to take it to a dealer just yet, just to get a opinion, because of the dealers hi  prices. If there is any help, please shoot out some lines thanks, Rizzo
