Clutch Slip on new clutch :(

[ChristoT]

When you reinstalled the clutch, did you make sure everything was lined up correctly? I recently reinstalled the clutch on my engine, and Deefer (the God of 600s!) mentionned that not lining up one of the last plates properly with the markings on the engine would wause the clutch to slip. I can visualise it, but can't describe it, which probably isn't much help!

Just for the record your oil is known good, it's the same I've used many times and the same two local yamaha dealers have used.

I seem to remember when it comes to the plates its not just as simple as interleaving then, there was two special ones that needed to be in the right position?

The half plate and spring washer do, yep.

Where are you, Phil? Maybe a mechanically inclined Foccer could drop round and take a peek in return for tea & bacon butties!

I had a similar issue years ago on my first Fazer.
 
Clutch started slipping, so installed a new set of plates and the slipping was still there, turned out that the front sprocket cover was so gunged up with chain lube on the inside it was stopping the arm from returning fully which was causing the slipping, might be worth a check.

Sorry for not replying yesterday guys.

You're really looking for that flaming aren't you?!

I left work after trying to adjust the clutch at the bar. To no avail, it slipped like a bugger all the way home. Got home and decided to have a look at the bottom point for adjusting the clutch, one snapped crappy screwdriver later I adjusted it and backed if off slightly.

Took it out for a spin and hey presto it's fine!

I'd forgot how bloody fast it is! Thanks for all the comments, seems the most obvious choice was the culprit.

Now back to the oil... I think it was the fact that I only had one kermit sock on that day...

I think it must have started slipping then or soon after as the clutch was nackered, coincidence rather than positive correlation.

Thanks again. I want to hear this oil debate continue! ;-)

When I pulled all the plates out I stood all the old ones on the floor with the last one at the top and them matched the old friction plates up with the new ones ensuring the depths were the same placing the new friction plate on throwing the old one off the stack and putting the steel plates on from the stack. I repeated that until I had put all the new friction plates on and all the steel plates from the old stack, so they all went on in the right way.


Its definitely sorted now, I rode into work on it today and I wasn't hanging around    and it didn't give the slightest hint that it was going to slip, even from low speeds in top gear with the throttle fully open. It just gripped and went.


Big smiles and a lot of relief!

Interesting subject, i've been reading it from the beginning and i had an inkling half way through that it was probably the push-rod adjustment.
I've replaced the clutch on several bikes over the years, British, Jap and Italian and i always start off adjusting from the clutch mechanism-up, the clutch lever/cable adjustment being the final one.
Glad you got it sorted.

G ; )

If the cable is too tight it's the same as riding with the clucth lever slightly pulled in so it'll slip

My contribution to this thread is relatively feeble but noticed my clutch slips occasionally with a bit of heavy wrist action.  Mate of mine bit of a bike nut suggested this solution which i might try on the basis of relative simplicity!!

[unfazed]

Your solution is a viable one because our local Bike Guru has  come across it more than once.
the funniest he had was a fellow come into to his garage complaining about the new cable he fitted had Focced up his clutch.
He was adamant that you should not have to adjust the cable because it was a new one he had fitted. 
When I called to his garage for lunch with him he was still laughing, because he actually had a job convincing him.
