Definitely not original. Looks like the ZX tensioner most people replace the stock one with, so you may be all set.

It may be worth pulling anyway to check to see if the spring was shortened. A stock ZX tensioner spring is too strong to just drop into a KZ1300 motor, so most clip a small amount off the end to drop the tension down. If you don't, it can lead to premature wear of all the rubber and nylon cam chain parts.

The biggest issue is that while the ZX tensioner has a ratchet-type locking system, the stock tensioner has a ring of ball bearings that jam the tensioner post and prevent it from backing out. These can wear after so many years, and slip. It works, but it's a lot less of a positive locking mechanism than that of a ratchet.

A brand new ZX11 cam chain tensioner spring has a free length of 87mm (3 7/16 inches). Finding that missing idle mixture adjusting screw spring was either sheer genius or extreme good luck. Losing the spring and then loctiting the screw in place is something a U.S. dabbler would do. Did your 1300 come from the U.S.? You are fortunate that super glue was not used.

Obviously, the previous owner was never taught how to do wheelies since the screw never left the engine cavity. But you and I have had triples and the reason the front tires never wore out was because they were only on the ground half the time :evil:
