I've done enough work that I figure I should probably start a proper build thread.
First off, a bit of background. I've owned a CB750 for a couple of years now, mostly because I lucked into a basket case that turned out to need a lot more work than I was anticipating. Because of this, my 750 has never really had a proper "year", but is really more a rotating collection of parts. The first time I restored it I settled on a vaguely 1972-ish outfit, which was fantastic.
This was fine, UNTIL I managed to snap a chain and hole the engine case. Thankfully, I had a spare set of cases in the back yard. UNfortuntely, this meant I would need to do a ground-up rebuild, again. But while teaching myself how to do a CB750 engine rebuild, I got a crazy idea- if this bike has always just been random parts, why not rebuild it into the bike I REALLY wanted?
Thing is, I've always loved the look of the K0 models. Not for the cultural significance necessarily, but the looks. The louvered sideovers, the colored airbox- it really is the best looking model of 750. But I'm never going to be able to afford a proper K0. So, I did the next best thing- took the spare '71 frame I had, sprung for a Yamiya body kit, and plan on doing my best to get a (mostly) visually correct K0, but with some quality of life upgrades from later models (two cable carbs, metal chain guard). For the record, I DID try to grab a proper K0 frame to start with, but those were prohibitively expensive. Especially since I had a spare '71 frame for free.
And here's where things currently stand today. I want to do some polishing and cleanup before I get the rear wheel and brake parts back on. I've got K2 gauges, but I'm fairly certain I can take then guts out of them and adapt them to K0 gauge plates and housings, so the parts to do that are on the way. The ultimate goal is to get it done for the Gilmore Car Museum show in Kalamazoo on June 11, but it's going to be tight.
