If your running dunes, id get +4". Thats the size I run and it works well for me. I can still wheely if I want too, but its not on the bikes terms anymore.

 

+4 would be good, thats thats what i run on my 686

 

A +4" should be just about right for you.I have a very potent 690 that i use a +4" on and it seems about right.

 

with a +4 can i still jump and run trails??

 

Yes you can jump.

Yes you can run trails.

You will want to revalve and respring the shock though. Ive preloaded my shock about a half inch over stock and cranked the compression up all the way. ITs rideable, but needs improvement.

 

where should i send my shock?

 

The best case scenario is to have a local shop do it. I dont have any in my own town, but am considering having a dealership about 40min away do it. Matter of fact, im gonna call and post back.

I used Shock Therapy Racing to rebuild my YFZ450 shocks.....They did a great job for a reasonable price!
