Plans are to keep the patina on the seat and tank. I originally planned on keeping the chrome but I think some of it is just too crusty. MotoLana makes some nice aluminum fenders.
I want to get it running, obviously, and then focus on suspension and brake upgrades.
I'm VERY interested in hearing about modern caliper and rotor options. I know the XS650 forks are pretty much a direct swap, and I've built a bunch of XS650's, so I'm a little familiar with making the stock forks better. I'm not opposed to a fork/triple swap, but I don't want to get into USD forks, wheel/axle spacers, etc. I'll be happy with optimized 35mm forks (or the 38mm if I can do it without too much work fitting the front wheel) and some really nice rear shocks. A good fork brace, sticky tires, etc.
Maybe down the line I'll look into a header/exhaust/muffler and a Mikuni carb swap, too.
