There's a bunch of racks available for the thing, but I think that it would be easy enough to make one. There's a local metal place that sells cutoffs. I was in there the other day and rooted through their bins, but didn't find the right piece, so I'll go back and look again. Eventually, what I need will turn up. I've made several things with material I've found there. They also have some plastics and I keep an eye out for pieces of Delrin.
As far as the bike is concerned, it now has a good skid plate, radiator guard, GPS wiring and mount, battery pigtail, fork gaiters, tank bag and has shed some unnecessary parts. It needs handguards, a rack and a few other things.
