@Betoney : Thanks for the reply. I agree about the linkages. The dealership never serviced them on the FJR, always had to do them myself.
I'm really wanting a quick and dirty way of being able to set up the shock preload as the ring nuts are concealed by the frame. I can't even get to the grub screw. Once I have it set , I can review it on a yearly swingarm service as you suggest.
