Anyone swapped a zephyr 750 engine for something else?

Will another Kawasaki 750 engine fit? or something else?

The only thing easy would be a bolt-one alternative, which is another Kawasaki air cooled 750-4, because that's what basically the 750 Zeph engine is, and of those, only the ZR-7 engine is newer and improved, but different ignition, different crankshaft timing rotor mount, and longer front sprocket shaft, make it somewhat an involved swapp overcoming the differences......I know at least a couple of people who did this, one with machining skills, the other one by modifying the ignition wiring (which is what I would do).

....even when most everything is possible throwing enough money, time, and resources, does not mean is practical, and everything else would be more expensive and complicated thant simply buying a different bike with the desired changes/improvements, unless you want a project for the sake of a project and time and money is no object.
