So, today was the day.
Got the bike up (and supported), wheel chock on the front and stands on the rear under the pillion pegs. I needed a slight bit more height so put 10mm of wood underneath the stands. Very stable, no concerns of it toppling.
All the nuts I had already loosened after soaking in penetrating fluid, so they all came undone without much persuasion. The suspension link swingarm pivot (at the top of the dogbones) needed a little gentle tap with the end of the ratchet as it had corroded a little in the sleeve.
All seemed lubricated already, not a huge amount of grease, but no wear marks or grooves (except for the slight bit of corrosion on the one pivot which brushed off).
The central frame pivot, however, would not budge. I swore at it in a couple of different languages, I whacked it, I soaked it in more penetrating fluid. It'd turn, just not come out (I presume, stuck in the sleeve). The exhaust was right in the way too for easy access for the hammer, so it had to be whacked remotely.... Left the nut on the end so I wouldn't damage the threads. The bearings feel OK, and it's swinging freely, so I do wonder if they've just not put any grease on the pivot bolt...
Eventually, after realising that if I continued I'd likely wash out whatever grease was in the bearings already, and/or damage them, I made the executive decision to just clean and lube the others. Washed out the grease, regreased with plenty of lithium EP2, and reassembled.
I will get my local garage to have a look later this year, at least all the other bolts will come undone for them!
Centre stand paint is currently setting, then that will go back on, after I've got enough motivation to fight the springs! 😂
