I'd been thinking about different pegs for the bike. Something a little more supportive and to more match the highway pegs. I ended up buying these at HDL to put me over the $100 minimum for their 10% off sale.
The pegs are P/N 1620-0207.
I took the whole peg assembly off the bike to work on it. It removes easily with a 6mm Allen head. Remove the cotter pin, remove the pin, and everything comes apart.
Reassembly is easy. The spring isn't very strong.
There is a small Allen head lock screw that keeps the peg from rotating. Loosen this to adjust the pegs.
I found the pegs felt the best when angled down slightly.
