Happy birthday Horse (my PCX)

Near as damn it 33,333km, so time for some TLC to usher in the "2nd trimester".
Stripped the rear end of the transmission down - replaced the driven face assy, clutch shoes, and replaced the belt.
Surprising amount of carbon came out of the clutch assy.
No great surprises thanks to the many videos I've watched on the topic (especially yours Homie - thanks very much). Only 3 head scratching moments ...
1. Wasn't sure how to get the packing grease between the bearings without it being wiped off on the shaft when I reassembled - but that turned into a non-event when I was able to inject the grease through the shaft holes and spread it around into the recess where it stayed quite nicely - only a couple of match head worth's was attached to the shaft when reassembled.
2. Clutch springs were far more problematic than first anticipated, but eventually I got the technique right.
3. The 38mm socket I'd bought for the clutch nut turned out to be something between a "friction fit" and "finally fitting into place after filing edges and hammering it into (and then out of) place. Didn't see that one coming.
Definitely a changed sound from the rear driven face bearings; not a heck of a lot quieter, but far less rough sounding. Definitely sounds much smoother. The belt had deteriorated since last inspection a few 1000 km ago - but still looked strong and not close to breaking. I plan to improvise a strength test to see how many kg it'll lift before breaking. New clutch feels like the bike did when I first got it.
Question: Clutch shoes appear to be a 3 part construction - there's the metal bit which takes up 98% of it's overall mass - then a "large postage stamp" size material that looks like cork (even though it obviously isn't) then another slightly smaller substance mounted to that which is of a similar colour. On my old shoes that 3rd layer was almost completely eroded away and there were a number of scratches inside the clutch housing. Just wondering if I seem to have judged the clutch plate replacement to perfection, or is that 2nd "large postage stamp" substrate also part of what can engage normally?
Brake shoes, tyres, brake fluid, valve clearance, cooling fluids all being done by dealer on Tuesday. Bonus - had the bike exactly 30 months today - just realised.
