I've owned this CB750K1 since purchasing it new in 1971. It's been off the road since 1985, but a few months ago I was challenged to get it back on the street. The first picture is what I started with.
As of this past weekend, it's waiting for the fuel tank to come back from getting the internals cleaned and sealed. It's promised for this week. Otherwise, it's ready to start up (hopefully!!) with replacement tires, tubes, etc. on order.
I'm bringing it back in the configuration I ran it on the street in the early 70s. Stock except for Yoshimura double disc front brakes, Yoshimura cam & pistons, CD ignition system, drag bars and Jardine 4-into-1 headers being the main changes.
Maybe it fits this thread - maybe not. If not, no offense was intended.
