George, get ready to be hooked. My biggest regret is not doing this earlier in my life. But also be prepare to undo all that you do. My wife asked me last week if I was going to tear my bike apart after every race weekend. I hope not, but tinkering with the bike is currently an addiction I can't shake!!
You're not on the bike for long periods at a time, so comfort isn't all the important. However, you wouldn't want to be so cramped you couldn't move around. I made attachments to the frame that allow me to change the location of my pegs. I built a dummy plate with 16 holes so I could move the pegs around and see what would work. I sat on the bike in my leathers for quite some time. But that still doesn't really tell you how comfortable it will be when racing. My point is, try to set it up so you could change it if needed. I, like many others I'm sure, used Brent's thread for inspiration. This is not a knock on Brent in any way, and I liked his foot peg idea, but I was worried about how I would change it if I couldn't tolerate the position, even if only for 5 or so laps.
I thought once I had it all together I would just race. Ha, was I wrong. At least so far.
