I'm finally retired and getting my old R100CS back to riding shape. I parked it in 2011 due to it not keeping battery charged even when ridden. I've got a higher output alternator ordered and says it's ok to use lithium ion batteries with it. I've run many of these in many bikes had excellent luck. For some reason the BMW crowd seems to hate them. I like them for the small size that doesn't have to be a puzzle to get in or out. The search engine doesn't seem to want to search it so I just figured I'd post and let someone guide me to the previous posts.
