I like the look of spoked wheels and I kind of want to stick with drum brakes for now, too, since I'd like to have a vintage racing look.
Maybe another bike I'll do a wheel swap, but this one I think I'll keep spoked & drum brakes.
I was at a show recently and talked to a guy that I know who has a mid '70s RD350 with stock tank, fenders & side covers, but RD400 alloy wheels, RZ350 LC engine & fork legs, modern radial mount calipers and huge trick brake rotors with alloy hats. He also used RZ350 rearsets and rear MC with an SRX600 swingarm and a bunch of other trick stuff. I totally know where you're coming from with the modern parts on a vintage bike.
