Just got finished putting the heel rests on the scoot... Unfortunately, I didn't consider one thing (and Tuna didn't mention it in his post either.)... The shifter pegs (pt #34706-07) will only work on the left side of the bike, since the back side of the peg is smooth. I went to the local HD house and picked up some Flame style heel rest kit (other styles available,) which come with a right and left side. Maybe HD will offer some knurled chrome ones in the future.
The installation was fairly quick - less than 30 minutes - and required only a spring clip plier, and a couple of 9/16" wrenches. Doesn't seem to hinder the lean angle much, but then I'm not pretending to be a crotch rocket rider on a Hyabusa either. In other words, if you're scraping the pegs now, you'd definitely be scraping the heel rests.
I'll try to get some pictures up in the next few days.
