My 1981 CB650 is being stubborn, will not crank. First i thought i had a starter issue, so i pulled the clutch cover off to find that the starter is spinning the gear that it is supposed to. (Not a motorcycle mechanic don't know the proper lingo) then my mind went to a clutch issue so i adjusted the proper tension and still have the issue. Im still not completely convinced that the starter is not the issue. Any advice or direction is greatly appreciated.
