This is my '83 KZ750 F1 LTD SHAFT. I bought it a couple of months ago and haven't done much to it yet. As far as I can tell, it's got a large 650 tank, custom fiberglass seat, rear fender cowl from a different model, dyna ignition.
I've brought the valve lash back into spec, ignition wiring & plugs, replaced/tuned the carbs & rubbers, and added the cheap emgo 1/4 fairing, European bars, that's about it.
I have an American Classix hydraulic slave for the clutch on order which I will pair with my KTM master. Should be pretty sweet because the cable clutch is kind of a sore spot when riding.
Getting about 45mpg fuel economy right now with highway riding. I think it'll do about 50mpg when tuned proper. Though the speedo is kinda busted as it only goes to 85 and sits there for some reason
