Thank you. I buggered mine. I'm not very good at soldering and the starter button is shorted. I can't find a source to rebuild and there's no source for new, only substitutes. The switch was used in 1973 for CBCB550 and 750K3 and 1974 for CB750K4.
I have the bike propted up in my back yard and everything thing else on the front, waiting, is as close to new as possible. The switch is a problem. And the weather will quit soon. And the holidays will start. And the tax season. And there I am with a rusty peice of metal missing a switch. Stuckage.
Help, please.
