rear spring removal to paint/powder coat
i want to paint or powder coat my rear spring from yellow to red or black. my bike is on a stand with no weight on the rear, and the exhaust is off. is it as simple as just unbolting the shock bolts and pulling the assembley out?
thanks

Nope. Spring isn't easily removable from the shock body (as in basic hand tools or it just slips off) like some other designs/aftermarket. At the very least, you'll need a spring compressor.
I recently posted this pic in another thread.
It shows an R1 shock I tried. The spring is from a Fox unit that I removed and painted to match. For those two shocks, I just had to run the pre-load the the absolute minimum which relieved enough tension on the spring that I could pry the bottom mount loose and slip the spring off. You can't do this with the stocker.

An automotive spring is longer and more easily compressed than a motorcycle shock spring. There's a special tool that compresses the spring by the bottom collar. Then there is another washer type doohicky with a slot in it that will slide out. The tool utilizes a 2 ton hydraulic jack to compress it. I would advise against trying to do it manually. You don't want to get hurt.

occasionally you can rent them. I want to empasize that done incorrectly and working over a very stiffly compressed spring you could lose a finger, an eye or even a head - not joking. Just walk the shock into your local shop and have them use their compressor to remove the spring for you and take it back to reinstall when painted. safe, easy and if they charge you to do it more than 5 dollars don't go back!

I'm pretty sure that tool only works on a offroad bike as those springs are similar to a automotive... longer and lighter to compress... The spring on the VTR is quite a tough one...

the more that i look at the dumber i feel...the shock and spring will come out as one unit correct? i was thinking that the shock would drop out the center and the spring would be left in the bike. it should come out all as one right? dumbass. sorry guys i making more of a job out of this then i need to i think!

Eh... not to be glib or anything... but "which" superbling???
I have so far seen... oh say three different shapes of it? perhaps more?!
Mr. bling likes to experiment me thinks...
And there are a few more of that kind around here...

By the way, Changing the spring was done by a guy with a really nice wall mount Snap -on strut compressor and great care, as it isn't as easy as a car. Careful, It will have your fingers!
