Author Topic: Clutch Plate Life Question - 2005 YZ 125 (Read 3135 times)

I have owned a 2005 yz 125 for the past 6 months and recently decided to do the 'shift stopper fix'. While I was inside the clutch I figured I would replace the clutch plates since they are the original plates and I had the bike open.

I measured the thickness of the plates and they were within spec (3mm), however the springs were out of spec.

New springs have been purchased but I am hesitant to pick up the new plates. The bike seems to run fine but the pads on the clutch plates look glazed.

My question - Is there a general rule to replace clutch plates over time even if they are still within spec? Am I just looking for an excuse to spend money?

Thanks - dk

Yes you are looking for an excuse.

There is no set time to replace plates.
Too many variables. Hours, how hard you ride etc.
If they are in spec and nothing is warped , put them back in.

You checked both the fibre and metal plates?

Sachs - I checked both (metal/fiber). Metal plates are not blued and lay flat.

TMKIWI - I like your take on the plates. My budget appreciates it as well! I have never replaced a clutch before and I was expecting to find some warn parts. To my suprise all looked pretty good but wanted to reach out to you all and get some opinions. Thanks

With all that you have said DK, I would just re-spring and ride... (i would use some heavy duty/longer springs)

If your clutch doesn't slip at WOT under a heavy load even with worn springs, I would say your plates are fine.

Thanks for all the inputs! I bought new springs already and put them in anyways. As I was doing this I was thinking 'does this really matter'. Oh well. Old plates and new springs. Its all buttoned up now and ready to ride this weekend.

Thanks again for the insight.

Na, run them till they start to slip. No point changing them if they still doing the job.
