  • It’s already been apart, I had to go digging when I saw that. Surprisingly, the tensioner blade (the plastic curved piece) and the metal arm that pushes on it (the two components that can contact the plate) didn’t actually look that bad! After a very late night reading the posts here and over on ZRXOA, I ordered the tensioner tamer. I like the idea of the factory part still pushing on the tensioner blade. (My automotive background leads me to refer to the curved piece the tensioner pushes on as the blade, and the straight piece of plastic-coated-metal on the top of the chain as the chain ‘guide’. Not sure if Kaw agrees, but...
    Im not at all happy about the about of lateral movement in the guide, though! Way too much!!!

    • This problem is common to the ZX900R (GPz900R) - 1000RX - ZX10 - ZZR1100 - ZRX1100.
      Why Kawasaki let it go for so long long is beyond me.

      I caught it on my 89 ZX10 before it was too late:

      From the log book a previous owner had a clutch basket destruction at 36,000 miles and replaced all the broken parts, mine was at 54,000 miles when I found this.

      I installed the Tensioner Tamer, which is pretty straight forward and is still available on ebay:

      I would recommend this fix or similar as an utmost priority.

      Just after I installed the new tamer, for my own piece of mind I took the oil pan off and found the following debris left over from the first explosion:

      Then this:

      And finally, just to really scare the crap out of you, the next photo is actually a piece of the original Kawasaki tensioner from the first explosion sitting in the oil pan its about 12mm (1/2") :

        Maybe a silly question, but is that zx10 tensioner fix bike specific? I have the same issue for my zzr1200 but can't find any parts

          I don't know if it is bike specific, the seller is in the US, his contact details from the ebay listing are 480-961-0643 or Pete@Hyper-Formance.com

          • Thanks for posting that info, ZX10.

            I had this issue on my 2002 ZZR1200 from about 60k miles until she died at 112,000 miles with no failure, but I was pretty smooth with my clutch application, throttle, etc.

            I had DWC do the fix - a homebrew recipe of his devising - when I bought my 2003 at 23k miles. 63k miles now and no hint of scoring.

            It's a problem worth getting ahead of for peace of mind if nothing else.

            • Hi guys, not to flog a dead horse with this post, but to save scrolling through all 199 comments, does anyone have a part number for the outer clutch plate? I'm going to get the els tensioner mod, but I would also like to replace the pitted plate. I'm sure it's painfully obvious but ive been looking at the oem clutch parts pdf and it's not jumping out at me.

                I suffer from kleptomania. When it gets bad, I take something for it.

                • Looks like (clutch-hub) maybe is what you want.
                  pn:13087-1121 From my pics it's the outer dish-shaped
                  piece under the clutch springs. Which seems to be the
                  clutch hub. Hopes this helps

                    even the teeth are all scratched.. do you guys think it's just that tensioner tamer like tomcat mentioned?

                    • Get one or fabricate one yourself. Guy on ZRX site has a kit, and there are others out there.
