Well busy afternoon for me, removed the mono-shock/pogo stick from the back of the 600, removed the dog bones and the shock linkage, good clean up of all the parts, washed all the needle/roller bearings out with W/D40 and gave then a really good clean and dry, repacked them with red grease (more resistant to water than regular grease) and fitted the new Nitron shock.
I did the work with the bike on the centre stand but slipped some thin planks of wood under the back wheel so it did not drop when removing the bolts, new shock and all the bits just slipped into place no lifting pushing or pulling involved.
Jobs a goodun.
Before I started working on the old girl I put a sticky label on the seat fairing vertically above the centre of the rear wheel and measured up from the centre of the rear wheel spindle 400mm and put a line on the label, with the Nitron fitted it now measure 403mm.
The unladen (Just weight of bike) sag is only about 15mm so I will set that to about 30mm in the morning it might just drop the measurement back to 400mm as well.
Then in a week or two will start on the front forks, I still need to source some linear springs. I have 15 weight fork oil and the YSS Emulators and a pillar drill in Terry's workshop (Wild Plum's) so almost ready to go on that.
Will take the bike out and try the new shock after setting the sag adjustment tomorrow.
