Reproduction cam chain tensioner for the Honda CB/CL/SL100 and CL100S. As your engine runs, the cam chain is spinning all the time and slowly wears all of the parts that guide it and put tension on it. If you're doing your top end and you plan to replace the cam chain and it's associated parts, it's a good idea to check for wear of course but sometimes it's good to go by the "while you're in there" approach.
