If the clutch springs are NOT the upgrade type, it may be a bargaining point.
The BMW is not a hard bike to work on, so unless there are some strange noises like something wants out, I'd grab it.
They are nice looking bikes for the most part, a few BMW models do leave me scratching my head though.
the only reason I don't own one is because I don't like shaft drive, owned one shaft drive, and rode a few others.
