Well in my attempt to cure the drag issue, (which I now realise is just a gas gas pro quirk) I replaced master cyl piston and seals, slave cyl o-ring and seal, new clutch plates set to spec, minor marks on clutch basket polished and sliding faces on new fiber plates polished too. Atf dex 3 oil used. Slight improvement but far from the point of being able to select neutral whilst sitting still. Just have to make do lol
