hi there
im going to do the clutch mod, i mean replacing the 2000 parts with the 2001 parts. on my 2000 yz426. i wonder if the 2001 wr uses the same parts of the yz2001 or not? i ask this cause in my country i can get only wr426 parts, the yamaha dealer does not sell the yz's...

anything i need to know before i start?

I did the 2001 clutch parts
Clutch went from grabbie to draging
pull lever to grip still draging
the reasion is the clutch arm is shorter on the
2001. if you change the arm also then clutch lever
pull is harder
I put stock parts back in and drilled 15 extra
holes in the clutch hub. much better and free
my advise - dont waste your money

Are you sure?

I thought the rod was shorter, or, more accurately, there was an additional steel ball between the actuating rod and the little cap that fits over the end of it that actually contacts the pressure plate.

I thought that since the two “special” plates from the ’01 amount to a thicker overall clutch pack the ball was added to account for this extra thickness.

I have an ’00 and ’01, I have a Hinson basket and stock clutch on my ’00 and the clutch on my ’01 is in a whole other world.

If you can make it work properly it is most certainly, in my estimation, worth the money to retrofit the three (or four with the little ball) different PNs to your ’00.

My two rupies.

Not the rod but the push lever (the part the cable
connects to, on top of the trans. )

The 01 uses a fiber plate with a bigger center hole on the bottom of the clutch stack.
then inside that hole is a seat plate(steel washer)and a spring plate.
The spring plate pushes the clutch stack away from the back of the clutch hub (boss)
This acts as a cushion so the clutch is smoother
But the pressure plate requires more travel to disengage, thus the shorter push lever

Hope this helps

That's weird. The clutch pull on my '01 is, as far as I can tell, identical to that of my '00.

It just works 1000% better.

I've removed the spring plate/washer (because of problems these parts have with the Hinson inner hub) and just run the '01 final plate. The clutch still works smoothly. :) I'll be running an Enduro this weekend, so it'll get the "acid" test.

I had to replace the counter balancer drive gear key for the second time though. :D Time for a new bike.
