WOW, great write-up and pics. One of the best builds I've ever seen. I'm a big fan of the DR, had one in Sumo trim, and my son still does. I would highly recommend the procycle TM40 pumper carb. With that, the airbox opened up and an FMF Q pipe, my sons DR put out 42.3 hp on the dyno. For comparison, my water cooled XMOTO (pipe and airbox mods) put out 48.4 on the same dyno right after the DR. From what I've read that's about a 10hp gain on the DR, really wakes it up. We have talked about the 790 kit.... maybe one of these days.
I do have one question for you, that hasn't come up. How you gonna get away with no front fender in Alaska? I live in the Seattle area and couldn't, at least, not if I actually wanted to ride more than a few times a year.
Anyway, Fantastic job.
