Thanks to all for the replys! I've got, I think, the original chain. If nothing else, to get it off I could just un- bolt the old back sprocket yes?, or the front one? in either case, I intend to change out the chain although yesterday I just tightened the old one and it ran like a top. However it still has some jerk. So as to the cush, could I use this one?
