My pain would be in my lower neck (close enough to between shoulders). Would start a couple of hours into riding. Temporary fix was to stretch my neck by looking downward, just long enough to feel a stretch. Butt hurts, too. (No, it is not because my head is inserted there!)
Have Bakup & Suburban footpeg lowering kit - I put on when bike was brand new.
Tried pre 04 seat - better for my butt, but (is that a like a double chin) still not super comfy after several hours in saddle.
Tried Hiway Ottomans - not really comfortable for my hips.
Tried XL jpegs - what a difference!
As soon as I get in high gear, up go my feet to the jpegs and I stretch out and get comfortable.
I'm now more comfortable and the pain between shoulder blades -lower neck pain doesn't bother me, at least not nearly as bad, now.
One thing about the jpegs - having my foot so far from the back brake with the attendant issue of stability in an emergency stop
(like for Bambi and the like) with feet up.
(We have a LOT of deer in NW Colorado)
I'm still working on spending the funds on a redone seat by Kontour, just haven't decided on whether I should send Ron K the pre 04 seat or the original seat..
