I installed the Buell pegs and wanted to share some info from the process, since there are some discrepancies with the Gen 1 and 2's. All that I had to do was shave approximately 1.3 mm from the top part of the peg. In the available instructions people shave off from the top and bottom. This is unnecessary as shaving from bottom of peg is not as straight forward. I used a belt sander which made it quicker and more polished than with a file, but a file will work just fine. The original bolt worked just fine and I replaced the springs with bigger ones from wide adventure-style pegs. The original springs won't fit. I could probably find springs that fit better, but these did the job. That's it. No sanding on the inside of the peg. Done in less than 30 minutes. I'm 6'3" and this has transformed the ergonomics of the bike. After half an hour I would get really uncomfortable because of the bent knees and was always moving my butt back in the seat trying to gain more leg room. That feeling is pretty much gone. Only downside is the slightly angled reach to the controls but not a big deal. For me it's more evident in the brake than in the gear lever. Highly recommend this mod for people with long legs. Cheap and effective.
