Giving this old thread a bump because I'm overhauling the old girl. She's getting a springer fork (paid good money for it years ago, so may as well use it - that, and if they aren't going to fill the small potholes, I'm going to need some suspension up front). So I dragged out the old, black springer fork from the first incarnation of Tempus, and started the process of painting it red to match the rest of the bike. And she may later get a new headlamp housing. To be honest, I'm on the fence about that. I still like the faux carbide lamp.
Also, in between coats (because, let's face it, watching paint dry is NOT exciting) I made a nifty little filler neck shield out of sheet brass. Not matter what paint I used by the filler neck, or clear coat, epoxy coat, beeswax, you name it, the tiny amount of fuel that would sometimes spit from the cap vent would cause the paint (or whatever) to always flake off to the bare metal in that exact spot. So I made the shield with upturned rolled-edges, and the hole was cut close so that it had to be pressed down tightly into place. We'll see how well that goes; but it should work like a charm.
