Hey bbar, welcome to the Vulcan madness. I see you have a few posts up now, but still have not introduced yourself on the Newbie forum.
Also go up to the User CP and fill out your profile and signature line to tell us a little more about yourself and your scoot that will appear with every post.
I finally got highway pegs installed on my scoot a year or so ago. I have Ma Kaw's Fire & Steel engine guard with the Kury offset pegs. Wingerline makes the only other aftermarket engine guard for the vn750 that I know of. It is quite different from the Kaw F&S.
The Kury offset is like a 2 or 3 inch long bicycle pedal crank that allows you to rotate it around giving you the ability adjust it in a circle on the clamp, putting the peg farther away or closer to the rider, and higher or lower.

There are also much less expensive pegs available, but having a little trouble finding them right now.
For comparison I am just a bit taller than you at 5' 10.5", and still pretty big at 270 lb now. (I have dropped 30 lb in the last year or so.
) I have my pegs set so I can use the stock pegs and highway pegs separately, OR rest my heel on the stock peg and my size 12 boot toes on the highway peg. Lots of variation in foot and leg position possible to help avoid the dreaded numb butt syndrome and/or cramping from long hours in the saddle.
