Re: Can 04' gsxr 750 motor fit on a 97' gsxr 750 frame?
Well, the motor mounts are different so that would take a good deal of fabrication - steel cutting, welding, etc... It's possible but quite extensive. The mounts on '96-'99 750 (and '97-'00 600) motors are the same but after that they changed.
Also, when you say complete with everything, does it have throttle bodies, airbox, ECU, gauges, fuel pump, sensors, etc.? I'd suspect you need to modify the tank and radiator too...
