Actually I think only the first friction plate (from the outside) is different from the next 7. And then the one as part of the cushion assembly has its own part number.

Still curious as to what the indexing of the plates versus the circular mark on basket does or doesn't do with regards to the last two.

As far as the spring goes I am replacing that assembly entirely with the Barnett setup I purchased from you over a year or so ago. The short push rod, ball, and o ring are being replaced also along with the big needle bearing. There was a little wear on the clutch boss but unfortunately that part is on backorder with Yamaha until late June so the old one will have to do.

I wouldn't say I "abused" the clutch but hard off road riding while fully loaded requires a lot of time in the friction zone and I think the increased pressure with the Barnett black springs will let the clutch engage quick when I let go of the lever.


The clutch in the state shown in the pictures still engaged well and didn't slip uncontrollably under full load for the rest of the trip. I think it just got really hot and the frictions glazed and then it slipped more than it should have and led to the excessive heat in the motor.

To be fair the bike has been over the Alpine loop fully loaded 2 times and Lockhart basin finally did it in as the bike itself was actually overheating due to the heat and slip.
I always thought the two first plates and their position was to act as a wear indicator. Clutch starts to slip before completely destroying them indicating a "problem". They rest on the basket raised portions to limit their travel. I'm totally guessing, but it makes sense in my mind. 8)

Re: Time for some fun...

Pardon me for off topic.. as couldnt help but notice whilst researching on the aftermarket clutch pressure plates.

May I inquire, what is the part number for the Yoshimura engine timing inspection plug?
