Re: Rat Rod Build Questions...Antique engine???
Hello Motion70, I'm Trey. Just showing my buddy our website, and he's over my shoulder saying you can run your gas high, and scorch it with a torch. Then wipe it down and the soot will color that case nicely. Obviously it would need to be fully disassembled, and then careful use of the torch. I can't say this will work, but this guy does know fire and metal.
Good luck! Please let us know what you do, and pics of how it turns out.
It's cooler to not fall off your bike.
