I was thinking about painting my spring and was wondering what all was gonna be involved with removal of the shock, breakdown of the shock to get to the spring, etc
Support the rear of the bike (by the frame, not the swingarm) remove the two bolts that secure the shock, turn off the spring retainers and remove the spring.

+1, you need to support the bike, but not any part of the rear swing arm. So some straps from a ceiling joist can work well. If you have a front stand or also strap up the bars to keep the bike upright too. You need to unload that rear.
Don't forget the springs get hot (in use and from the exhausts) so use hi-temp paint. - Chris
You're also going to need a spring compressor for disassembling the shock and reassembling it.
Pompetta came up with a great idea of using a rubber tube with a longitudinal slit in it to wrap around the spring coils and make it easier for the compressor to grip the spring. It also protects the finish of the spring's new color on reassembly.
Also, powdercoating works well on the spring.
Make sure to post pics. wt:

A completely dodgy, non recommended way of doing this that _I'd certainly think twice about before doing, again...
Support the bike on a rear stand, put a block of wood across the frame under the passenger grab rails, and put a scissor jack between it and the back wheel and jack it up just enough to remove the weight from the shock/spring assembly - you can tweak the jack up and down until the bolts holding the shock are unloaded enough to pull out (you'll need to remove the hugger if you've still got it fitted).

Oh, come on. You know you'll go right ahead and do it again without a seconds hesitation, 'cause it works so well.
As long as you remember to not turn the wheel :P

+1. This is MUCH easier than the other beam method. I'd suggest wrapping a rag around the block of wood so you don't scratch your grab bars. Also if you can I would get it powder coated not painted.
Im gona +2 on the scissor jack method. Its really simple. [thumbsup]
OK, if anyone asks, you got this idea from uclabiker and vindigo, right?

Yeah, the jack between the wheel and frame method is easy, but the penalty for failure is higher. If you've got the frame hanging from the cieling there's about nothing to go wrong. If your wheel spins in the other method, your jack falls out, and the weight of your bike comes down with no rear shock. You probably won't cause any damage,but you might get the linkage wedged and full stuff.

Here's a thought.
Scissor jack method with straps hooked, but not taut, as a safety?
Just throwing that out there. [thumbsup]
I like to put the bike up on a rearstand and front stand, then put a piece of wood under the engine with a floor jack (or two), then remove the rearstand, if you do it right, it's very stable... My garage has questionable rafters, so I don't like to put weight on em...
I use a steel rod through the swing arm pivot and automotive jack stands.
