now, as I understand it, all harley V-twin engines of the last several decades, as well as the aftermarket versions ( big dog, ultima, S&S, revtech etc.) all share the same mounting configurations...

is the same true for vintage japanese inline 4 bikes?

I am wanting to find a decently priced rigid frame for my bike, but it seems that no-one makes parts for anything but honda CB750s...

so would a frame made for a CB 750 be able to mount a KZ1000 engine, or any Distance from Cleveland, OH to Columbus, OH of the other engines?

My pure guess is most likely not without major frame changes. But I could be wrong.

No they don't nor do they share the same sprocket offset from the centre line of the frame, exhaust port spacing, or sump configuration. The only thing that's "universal" about universal chopper frames is that they universally fail to fit anything properly. You could hardtail a stock Z1000 frame, or scratch build one?
This is my GS550 in a chopped stock frame.
