First time i did it i removed the tail unit and hung the bike from the roof of my shed with tie downs. Now i use a stool the same height as the rear wheel behind the wheel and run a plank between them and with various offcuts of timber i position a scissor jack under the subframe and take the weight off. I'll take a piccy and post it up because i'm sure my explanation sounds confusing.
CYA, Kev.
Should still be plenty of clearance with plastics in place.

Up on the paddock stand and, if you have non folding footpegs, axle stands on the rearsets.
Or up on paddock stand and suspend by rear subframe from a garage beam or tree.

If I remember right, you can put wood blocks or a jack under the frame/swingarm mount plates that run top to bottom either side the bike to hold the back end up, if you don't have a beam handy to hang it from but you need to take the downpipes off first, if you see what I mean.

And then you'll be back asking us how to remove the forks because you realise how crap your front end is when the Ohlins goes in

I have a pair of WP race springs spec 90Kg driver + racetech cart emulators wich where supposed to go in at the same time....but i had a change of heart yesterday....
I´m going for linear K-tech springs and the emulators....
So if anyone would like to buy a set of WP springs.....

If the WP springs and the K-tech springs are single rate springs of the same rate ( I weigh 95kg with all my gear on and use .9kg/mm springs for the road and .95kg/mm for the track) then as both are premium brands there will be no difference in their performance.
On the other hand if your WP springs are progressives then by all means get rid of them
FWIW I find the Race Tech emulators are fab. My settings are 1.5 turns rather than the 2 turns in recommended by Race Tech ( 2 turns in on the track with the .95 springs) with 20wt fork oil with much LESS oil than stock. I can pull the springs to measure if you need exact figure.
Ohlins tend to supply shocks with a spring rate the same as the stock shock. I would order the Ohlins with a stiffer spring than the standard TRX rate of 7.5 - 8kg/mm. I now usea spring 10kg/mm, 9 to 9.5kgmm if you are lighter than my 95kg ready to roll.

It'a always best to finally torque the shock/linkage bolts up with the bike at it's normal ride height - it saves the bushes trying to shear under full compression (although not a problem if the unit uses metal rose joint type bearings)
