No hard number that I've ever seen.

Missing a spacer in the slave cylinder, or is the pressure plate button different to the one removed?  Just looking for a few mm somewhere  ;D

...or perhaps the old PP bearing was bad causing the pushrod to 'drill' it's way into the slave piston?

Yep, a few mm there, and strange feel.

I have been wracking my brain over the last couple of days about this. Back when all of this started I had the feeling that there was something wrong on the lever side, it didn't feel like it was working right at all. The furthest I could pull it in was about 1" from the handlebar. I cannot remember for sure, but I believe it used to come all the way in and rest on the handlebar.

Anyway, that is what got me to looking into everything to begin with. If you go back and look at the first set of images you'll see where the basket and tangs (tabs?) on the clutch plates are worn terribly and VERY rigid. What I assumed was happening was that the tangs were getting bound up in the ridges of the basket and when I pulled in the lever there was not sufficient space being created between the plates.

I know believe that that thought process was wrong. I believe that the old plates only worked because they were THAT much thinner than the new ones and while the "push out" was reduced there was just enough clearance to allow the plates to mostly space apart. The new plates, being just a c-hair thicker, don't work because the pressure plate isn't going out far enough.

Which in my mind brings me back to the master or slave.

If the rod had pushed back into the slave a few MM, do you think it would show wear on the end of the rod?

Koko, for the life of me I cannot come up with any missing parts,

Sorry for the long winded post, I just wanted you guy to see my train of thought.

The pushrod is steel. The piston in the slave is likely aluminum. The wear will be in the slave piston, if any. You might be able to remove the slave and carefully remove the dust boot to check the piston surface. It will be concave by design, but if it has an impression the exact size of the pushrod, you've found your issue.

Beers are on me if you can make it to a nicely thawing Texas!

I've gotten a vacuum pump so I’ll give it a bleed to eliminate that as a problem.

And see what I can see inside the slave.

I’ve seen the pushrod adhere itself to the button in the pressure plate many times.  And by adhere, I mean just short of weld itself to the button...

Check it *all* before making a judgement...

I appreciate you jumping in, but I am afraid I don't understand what you are saying. Can you clarify?

Are you saying that the rod has gone deeper into the button, basically making the rod too short?

Not that it makes the push rod shorter per se.  The push rod digging into the slave cylinder is more likely.

Well boys, it was loaded up and brought to the dealership yesterday, I have thrown in the towel.

A buddy came over and bled it over and over and when all was said and done the clutch lever felt EXACTLY like it did when all of this started.  :P

So I am currently of the opinion that there is something wrong with the master or slave and that slow failure is what lead me to look at and replace the plates. Clearly they were needing to be replaced sometime soon so I don't feel like I wasted the money, I just didn't fix my problem by replacing them.

The guys at the dealership agreed that the lever didn't feel "right".

I'll let you know what they determine.

It turns out my slave failed. It was an Oberon. Do you guys have a preference on a replacement: Oberon again, Ducabike?

Thoughts?

I ordered a Ducabike slave.

Glad it got figured out. Did they say what the failure was?

Oberon have a good rep, but mine failed in a very short time. Strangely, I've have good luck with late model oem.
