You can fit any motor under 100 hp , the frame can take it, its all going to be a custom job unfortunately as you will essentially buy a donor bike and take everything it has and transplant it in to the 650 frame. Also expect work to be done , either frame bracing , welding , alterations to make the motor fit.
Some people try an easier way buy just getting the SV650 Suzuki and take everything including electronics
Sky is the limit though!
Why swap though ? I am curious as the GT650 motor is better than the SV one by a margin (if tuned well, carby is easier)
