Since the previous owner didnt know exactely when (might be 5 years or 15000 km ago) he changed all CVT-essentials, it was done today.
Scoot did not have any issues, rollers had some small flat areas, belt (pls see pics) looked good from outside, but when you turned it had already little cracks.
Rear oilseal (clutch) had a fine misty area of oil around, so both (crankshaft & rear seal) were changed (both oilseals € 8,40 wholesale).
For rollers: experimented again with TechPülley, 23x18-18gram (OEM 23x18-17gr).
Gliders: (pls see pic) were worn out on the "pushing" side and prone to brake somewhen
Uneventful little dust inside CVT casing, kitchensoap, waterhose and air treatment.
Here the philosophy is to change from 250ccm up belt (€45,-), gliders (€12,-) and rollers every ten-thousand (10) kilometers, to be on the safe side. Squares (€38,-) might last longer, if without this little wings.

Ruffus, how did you pull the oil seals out? I've seen various methods described..drive a screw or 2 in and pull straight out?

@hawk, very easy.
For more than fifty years same method.
I take a small but sturdy screwdriver,
-set it on the OUTER UPPER rim of mounted oilseal,
-apply ONE sharp but measured hit with a hammer on the screwdriver
-oilseal bends in (pls see pics)
-pry it carefully out without touching anything but the seal which is anyway scrap
Oilseal is a metal profile covered with synt rubber, so it stays bent in, easy to remove.
I do have a special seal remover but this works only at bigger diameters AND scratches (if sloppy applied) the axle.
This two screw method works too, but if you get tilted, you demage the seal area (mostly aluminium).
EDIT: put KYMCO gliders pic just for reference

thanks, Ruffus! I haven't seen that method used, before. It looks easy and effective if done carefully.
