Yeah, I too think it would be cool to de-brand the bike's sidecovers. If you want to post it to me, I could fill it in with some TIG bead. They you'll just have to sand it down and polish her. Perhaps in exchange for some powderwork. PM me if interested.
Also, I'm using those same gauges on my RD400. They really are the dogs balls. I think I'm going to mount mine below the tree so they don't stand so proud. The headlight ears fix the height of the headlight, so hopefully it will not interfere with the clocks. I just got all my stuff back from powder, so I should be reassembling everything this weekend--famous last words.
Also, I haven't gone through your full build, but if you haven't done so yet, I'd be interested in seeing your powder setup: the oven/s, equipment, etc.
