Re: Hip cramps and rear sets?
I did the same on my K5 1000
I was using it mostly street, so I bought a set of those riser plates for the rearsets of ebay, and put them on upside down. It moved the pegs down alittle and back mostly. It made it so much more comfortable along with shaving alittle bit of foam out of the seat.
I did 500-600mile trips without issue.
Edit: I had to move the brake reservoir down about an inch, I just made alittle aluminum bracket to move it down.
