Engine mounts are not in the same places and the two engines are not the same shape and the ignition system is not compatible, and the old Ninja 750 engine was designed for side-draft carbs so the intake ports are at completely the wrong angle. And for all your trouble, you will get a non-fuel-injected engine that eats camshafts and rocker arms (been there) and makes no more power than the 636 engine.
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
