ZX12R clutch
Hi guys,
New to the forum although I have been viewing for a while. I bought a ZX12R powered Stuart Taylor Motorsport yesterday and half way home the clutch
started to slip (only under heavy load). The car runs fine on part throttle but slips when pushed.
Does anyone know if there is any adjustment on this clutch and if so, is it straightforward? If I am unlucky, then can anyone tell me how easy a
clutch change is and what upgrades (like Muzzys maybe) are recommended for this unit?
Thanks in advance

I've never done a clutch on a zx12r but bike clutches are relatively easy to swap and not mega costly (IMO) either.
I would recommend you get a manual (Haynes) for the ZX12 though - it will help a lot

You might just need heavier clutch springs, TTS sell them amongst others. Dead easy to fit, as are clutch plates if you need them.

ZX12R clutch
Thanks for the replies fellas - that was quick! The car is already supposed to be running heavy duty springs (not sure what type though). When you say
that the clutch change is a simple job, does that mean that it is done with the engine in situ?
Cheers,
George

if you have room to take the clutch cover off in the car then no probs but if there's no room out it will have to come good luck

I don't know what it'll be like with a 12R, but with my bird, I find jacking the front of the car up a few inches helps keep all the oil
inside the engine! The clutch is generally a case of whipping the cover off, undoing a big nut or two and pulling the plates out. If there are any odd
plates, or different coloured ones, make sure you get them in the right place. Mine has a different inner and outer plate.

As suggested, best to buy a manual and just follow the steps. It will also give you minimum thicknesses so you can check the plates, buy a cheap
digital vernier for checking them.
The procedure really is dead simple, but you'll feel more confident with the manual as a guide.
As said if you lift the front of the car high enough you wont even have to drain the oil. I use a block and tackle when i do mine.
Good luck
Al.

It's quite easy to remove the selector forks. You first need to remove the oil pan, the oil pump drive gear, gear position switch and gear shift
mechanism.
Remove the bolt and screw on the bearing holder and then pull the shift rods out, taking off the shift forks.
