DP clutch problems

8 posts in this topic

I just bought a new dp clutch for my 08 yz 450 and it came with 9 fibers and stock has 8 . Evin when i put 8 of the dp plates in the clutch still won't dissengage ( with adjusters all the way out ) the only way i can get it to disengage is to use 7 fibers and stack 2 steel plates together. I have not ran the bike yet and think the kit may have been miss packaged ( cheked the part # twice and it is the right one ) I was wondering if there was something that i was missing.

The clutch kit for an '07 and later should be different from the 9 plate stack for the '06 and earlier models in more ways than the number of plates.

The thickness of the steel plates is different, the springs are different and the pressure plate is different, as is the release arm. Unless these parts are changed to match those in the '06, I don't see this setup working.

The only chance you might have of using these new friction plates is to use them with the correct OEM steel plates.

Essentially, it would appear you have the wrong parts.

Hey guys...I have always used the stock clutch in everything. But because the clutch is a weak link on the 08 YZ450F (can't stand up to much abuse) Do you guys know of an after market that holds up under abuse in the 08.

Please only if you clutch a lot and only if you know for certain. Opinion based on factual experience in this bike.:lol:

Thanks

Convert it to an '06 clutch. Use the '06 plate set, springs, pressure plate, and release arm.

9 plates vs. 8, for one thing. 12% more clutch with more spring pressure. Should still be easy to pull; both mine are.
