Looking great, Noddy.
I agree that it looks great raw right now, but I think that a distressed paint would not look out of place on the bike, and might kick it up yet another level.
As for the wiring harness, I don't know if this is available anywhere, but I think that small canvas hose (like a tiny diameter firehose) would look spiffy as a means of wrapping/hiding the wiring, while being well in keeping with the overall look.
