Slipping clutch

only does it when having some serious excelleration fun when riding fast. Not sure which gears but more than likely 3rds - 5th, only slips when it hits 12,000rpm which is bloody annoying cos the power is 10-14 so means I cant have any real high revs fun. Tried bogging the engine down and excellerating from 4,000 no slipping anywhere else.

Been suggested I try an oil change first to see if that cures it :?

anyone else had this experience and know what to do or is just replace the clutch and be done with :?:

Fully synthetic oil can cause a slipping clutch, but now that it's slipping the plates will be inpregnated with it and be wearing so no point in just changing oil. Clutch plates are about £40 so I would change them and use a semi synthetic oil. BTW, they are very easy and quick to change :)

My plates have been slipping for aaaaaaages - i'm gonna do it myself as soon as i've payed my insurance!!! :D

Does seem like a pretty easy job.

So it's about £40 to do it yourself - or £150+ to get a garage to do it for you......

http://www.bargain-biker.co.uk seem to have some of the best-priced kits.

Don't bother getting new plates until you try the following. Dismantle clutch (really easy to do) and wash them in some form of degreaser. I found isopropyl alcohol does a really good job. Soak them in semi synth oil and reassemble with fresh semi synth in the bike.

Worked on both my ZXR and TL1000s

Cheers

No good for me Techie!!!!

Mine's slipping cause some crazy bugger got it bored out then went off racing his mates on a ZX6-R and a Bandit 1200!!! :twisted:

Hehehe - can't wait to get full power back, either!!!!

What's with all this cork, kevlar, cork/metal type stuff in relation to the plates???

I'm assuming the plain cork is for grannies riding CG125's, and the kevlar is more for race use?

Agreed, IF you know that there's fully synthetic in there. For the sake of £40, why bother to go to all the hassle (and expense of buying degreaser) and then maybe having to take it all apart again if it doesn't work :?: :? If you're skint, fair enough :lol:

BTW, always use genuine Kawasaki plates, not aftermarket ones. Apart from being cheaper they are the best, as used by most racers in the UK.

I would change oil (silkolene 10w 40 ride)ive used it for 3 years :D
I would change the plates and the steels and springs ring bartons ask for discount should cost including gasket about £80

I would change all these on the list because if it slips again at those kind of revs you can kiss youre engine good bye been there slipping clutch valve straight through piston :cry:

Soak the plates and steels in oil for a couple of hours or longer and no more slipping clutch for the extra £20 replace the whole clutch

Hope this helps if youre near cadwell or pembrey when Bemsee are racing pop along i will allways do the clutch free of charge only takes 10 minutes

Good luck :)

They only sell a semi syn in the ride version its when you buy the expensive oil like race when you need to look at the label
