I agree with GSXR Freak. If you are going to go thru the hastle to make that motor fit, you might as well make it FI. I did one a few years back, get a complete harness, guages, and fi system and airbox. Use a 98-99 FI fuel pump
The problem with keeping the carbs is that the intake spacing does not match up. You would have to fab up some intake manifolds to change the spacing from the 01 head so it would match the spacing of the 96 carbs.
Even if you got that to work, you would still have problems with the crank sensor not matching the ECU of the 96... So many things that you would have to make work, it would cost a LOT more in the long run.
