0-ring chains hitting engine case

<< < (3/3)

kxcam22,

I don't know if these are the right parts. But my 87 doesn't use a circlip.  It has a washer with the i.d splined to match the counter shaft. after the nut is torqued you just bend one side of the washer up against the nut. I have about .040-.060 of counter shaft sticking pass the nut. I will look at kawasaki.com and see if I have the right parts.

KXcam22:
Hughes,
  Mines a '92. They must have changed how the CS sprocket mounts.  If your CS shaft is not tapered then you might be in luck. Would be simple to buy a 2nd one of those splined washers and place it on the back side of the sprocket to space it outwards.  The nut will take up the clearance. Cam.

I going to give it look and see what I can do. The chain rubbing is not hurting anything right now but it does bother me that it is rubbing. Just got to run my new gearing today 14/49 man that's what I have been looking for. Now I am leaning toward a flywheel weight. Thanks for ya'll help.

--- Quote from: hughes ---O.k Guy's I know this has been talked about buy I need to make sure. I just installed 14/49 with new o-ring chain and it does hit the engine case. I know alot of ya'll are running 0-ring chains are ya'll having any problems with the chain rubbing the case :?: I know kxcam22 did a neat mod. but don't have time for that at this moment. Thanks

There is a rubber o-ring which fits behind the spacer that the sprocket rests against. I just used two of the rubber 0-rings before slipping the spacer on the shaft. This makes you have to push the sprocket to compress the rubber 0 ring and get the circlip to fit. No more case scraping.  :D
