Clutch 'chudder' after basket install

[Dogdaze]

CW, merge this if I have asked the question in the wrong section.
As per title, has anyone experienced this? I replaced my '12 basket with a complete '14 upgrade, including plates, steels, diaphragm spring and anything else I took off was replaced with new parts and oil and filter of correct grade about a month ago and 400kms. At first on start up and engaging first gear the bike now lunges forward hard, very disconcerting, but I apply front brake so not entirely dangerous, this goes away once warmed up, never did that before upgrade. Yesterday I had new tyres put on, RP4 Trails, and today along with the hard first gear engage I now have what can only be described a 'chudder' on take off as though lugging under load. I'm not doing anything different as far as riding goes, I did grease the cush rubbers though before reinstalling wheels. I also bled the clutch when I did the basket. Any ideas?

You got it in the right section, so thank you for that.


Sounds like the clutch is still dragging. As a clutch wears the friction stack gets thinner, just like worn brakes. Just as with brakes, the slave caliper extends and can build crud which can keep the piston from easily retracting. My suggestion to start is to simply disassemble and clean the slave unit and piston.

CW, so you're saying not to re-open the clutch side, just the slave cylinder and go from there? I was contemplating sticking the old plates and steels back in.........

I'd start with the easy and obvious slave cylinder. It's a good idea to do it anyway when doing a clutch.
You can still see if you have a bent plate after that, which would be the next most likely suspect to me.

Could the ball bearing have been left out?

I laid everything out on clean cardboard and some underneath the bike, nothing fell out and all parts taken out were replaced in order with same or new part...... took me 1 1/2 hours to do, just so that it was done without a glitch. I will check the slave cylinder tomorrow, I did reverse bleed this evening and it seemed better, at least on the center stand.

I always soak new friction plates in oil for a few hours before installing them. Did you do that?

Over night.

Ok, just an update, as I hate a story with no ending. I ended taking off the slave cylinder, looked new, checked under the seals and all good, of course now I have a sh*t load of air in the system, so started the messy task of bleeding the lines from top to bottom and bottom to top. Also removed clutch plates and replaced the last 3 plates with the old ones (they were soaking in oil after I took them out) after inspecting all of them. Took it for a ride this morning and seemed much better, it may just be the new tyres and new plates were causing too much 'grip' but the clutch seemed to have 'bed in' a bit. I'm hoping things will get better over time....... Will update if things improve, and if not, trade it in for a new one. Life's too short to not enjoy a few things.
