Progressive Fork Springs Install Questions

If Id looked into it more I probably would have went with the Sonics but the Pro's just got to the door today.
After opening them up Ive got a question. Are the PVC tubes that comes with the springs cut to length? Also looking at the service manuel just how far do you have to disassemble the forks to replace the spring once its off the bike? Can the stock one just be pulled out from the shock and new one slid over the damper rod?

Well shock are off and apart. No the PVC is not cut to length. Progressive springs are two inches shorter then stock. Well shorter then the stock ones after taking a beating. Service manual says replace the stock ones if there shorter then 17.4 inches. Mine are at an even 17.
Do I just add 2 and a half inches to the length of the stock spacer and cut the PVC to that length?
Do I cut it to make the combination of spring and spacer flush with the extended fork so the pre-load starts as you tighten the cap down?

Sounds like if Id bought Sonics Id have answers. Damn it! Live and learn.

I have Sonic springs. Besides, JohnofChar answered your question at VSRI and most of what I know about V-Stroms came from reading his stuff. I thought for a moment of posting to shim the spring so it came just above the top of the tube because that's where I remembered the Sonics came to but they are not progressive and I wasn't sure I remembered correctly. I believe John said 1/2" to 3/4" above the tube.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s
See https://www.stromtrooper.com/general-...nicknames.html

Yea I had feelers out on both site's. Went with 3/4. What a PITA to start that cap back on but with some persistence its done. It'll still be a couple of months before I can feel the change. Im sure it'll be a big one. Thinking about that group buy for an Elka shock too. Winters in Alaska are hard on the wallet! Thanks for the response.

You've got too much preload. See the "Note A" section here for directions on cutting the spacers to the right length.
