Yes, the master cylinder seals were ruined from piston debris not being cleaned after machining.

Same here. My 2015 clutch lasted for half a ride and then started losing pressure.My dealer replaced it with a brand new which I still have in the box as I had a clake one finger from my old gasser which I used.

my 15 played up as well in short time. Iv bleed and changed the clutch fluid but haven't really given it a work out since. ATM gasgas Australia has 50% of parts as they are changing distributor. Ive ordered a magura master off another model as its dirt cheap, a seal kit for my 15 and a heap of other bits.

are you meaning from new ? as in from the factory ? I've had a 125 that I've rode approx. 45 mins with no issues, then another 15-20 mins and piece of what appeared to be "welding slag" was found in the slave piston area, seal was toast, and it beat on that end of the slave cylinder...enough to warrant replacement... I am trying to understand how anything could be in there from the factory ! I've never heard of it before on a new bike anywhere...

Yes, from factory, straight off showroom floor. It was just poor quality control from AJP. I know of 4 that had the same problem and 2 that didn't in my area (14/15's). Replacement with a Magura master cylinder is the easy cure, has a much better feel also.

You say your slave piston seal(on engine) was damaged? I don't follow how that had any effect on the master cylinder???

sorry, maybe I have confused the thread as "clutch" in general...my problem is at the slave end...
I've had to order 2 pistons @ $50.ea , and today I ordered a slave cyl. assy. from Matto. God knows what that will cost
if ya need it, ya need it...

The frictions were worn down to the point where the standard grooves were barely visible. They have almost 7 seasons of use.

I'd guess that deeper grooving allows the frictions to sweep more oil from the steels and reduces squawking. The improvement I noticed might be from the fact that the plates have grooves once again.

It is a time consuming job considering that there are 36 grooves x 2 sides x 8 frictions = 576 grooves. Maybe I should use them for another season to justify the work.

If I get new plates, I better get a spark plug too (just to keep Mr. F5 happy).

I think I did about 2 grooves and decided it was easier to get earplugs so I couldn't hear the squealing
