2008 slipper clutch mod

Hi, first post on this forum!! does anyone know if the 2008 silpper can be modified in the same way as a 2007 r6?? i have been racing the r6 since 2006 and for next season will move to the 1000 class with a new zx10r.
now i have looked at the clutch diagram and it looks like it has the same setup as the r6 with the springs that go on befor the cluth hub nut, on the r6 it had 3 three leged springs and what you do is take them all out and cut all the legs off 2 of them ( making them into washers basicly)and refit 1 without legs 1 with lesgs 1 without legs
I have attatched a pic of the zx10r springs and to look at they are the same as the r6 springs
any info welcom.
cheers
Ian

It sure would be a simple thing to do, but, what exactly does it buy you? Does the stock springs' pressure cause some type of problem during certain circumstances?

There is a slipper clutch mod and I have it done. What it is is a kit judder plate. It reduces the chatter so you can do higher rpm drop downs when shifting. I am trackday exclusive and rode with this mod all year. I loved it!! There was no chatter in the rear wheel when shift down fast and hard to setup for corners. I also had no problem with it holding the power. If you search for the kit manual in the search box it has it detailed in the transmission section. At least it does in the 06-07 kit manual. It does require some adjust me of the clutch pack thickness ie. varying the thickness of the friction plates. It also talks about adjust the clutch pack thickness to allow for more or less slip with this parts. It was not hard to do just a little reading and the right parts. Here is the part number for the 08 part. I believe this works for all years as well.

13089-0012

Also did some more leg work for you. This is from the kawasaki website

Thanks for the replys!!!
the more i look at the clutch the more i want to try cutting the springs
im going to give it a go but i will not be able to test the results for a few months as its -5 outside, if it work l will post the results on here, when i did it on the r6 i had 2 bikes and my #1 bike had a sigma slipper in it and the wet bike had a std clutch with this mod and it was that good that it made me think that i had wasted £600 on the sigma.
Hawk kawasaki do a mod on the zx10 clutch without using any kit parts (i hope i have found it) ill let you know.

I have bought a full arata sytem and a pc3 for the bike, does anbody know if the is anymore power by fitting a ignition moduel.
cheers

Good luck trying this mod Ian, I'll be very interested to see how it works out.

Cheers,

Question

Exactly what do you do and I will try it. I can still ride every other day when it is not freezing or raining outside. Will I need another clutch cover gasket or will the old one still be good. Oh by the way I have the 05 ten.

Is it Fast?

I still don't get it. Those springs are pretty weak any way. If you make them weaker, what are you allowing to happen? Does the clutch slip earlier or easier? Like when you are not really decelerating very hard?

What are the consequences? Or, to ask it differently, why didn't Kawasaki put weaker springs in there?

Just curious.

I think they allow the slipper clutch to engage on downshifts at a certain rpm. If you make them weaker then theoretically it should let the clutch slip earlier. It can only slip one way due to the ramped slipper design. I like the idea of my clutch slipping easier. I really don't need the engine braking as much and I can settle to enter a turn alot easier if that happens sooner.

Is it Fast?
