I have an 83 XVZ12 and there is this noise that comes from the rt side of the engine that sounds like a chain slapping against the inside of the cylinder/upper case area BUT when i set the bike up right it goes away... back on the kick stand and its back, loud slapping sound..
could this be a stretched timing chain or a broken tensioner...
can the chain be adjusted or is it an auto tensioner?
doesnt seem to effect the engines performance but sounds like its going to fall apart...
any ideas???
