Changing a clutch on a YZF750?

[Gord]

I've changed a clutch on an R1 many years ago, but can't remember exactly what I used and how I done it.
My clutch doesn't slip, it just doesn't feel right, there's not much clutch and it's very snatchy.
What parts do I need and have you got any tips on changing the clutch?

Assume you've checked slave for leaks n changed the fluid

[Gord]

Yes, but that was last year, so will change the fluid again and have a closer look.

The clutch on the R1 & the clutches on the Exup are completely different. The R1 uses a diaphragm plate & the Exup uses springs.

Both are easy to change plates. But if the clutch looks like this



It is no surprise that the clutch action is not smooth

Does anybody know if there an explanation on how to change the seals on a clutch slave cylinder on the forum?
I'm going to change the seals and fit a new braided hose over the next couple of months and see how it goes, before fitting a new clutch kit.

[YAMAEXUP]

It does tell you how to do it in the Haynes manual & is quite straightforward. I changed the hydraulic clutch hose to an Areoquip one & together with Barnett heavy duty springs made a world of difference



You can still buy the slave cylinder repair kit & I preferred the OEM over the pattern one as there was little if any in price between that & a pattern kit



The other mod was to fit a master cylinder from a ZXR750R

[Gord]

What difference did you find in the ZXR750 MC? After new year, I'm going to change the seals, the hydraulic hose and a full clutch change.

The ZXR750 m/c gave a lighter pull....& it looked better than the OEM one.

I'd go with Barnett clutch springs from PDQ before changing the clutch plates. I've still got the same plates even after 55,000 miles, but i've got some OEM plates oiled & waiting to go in as & when they're needed
