I just picked up a motor out of a 03 gsxr 750 to replace my motor out of a 01.I'm noticing the throttle bodies are slightly different.will my harness work with the 03 injection ? The motor I picked up did come with the harness and ecu.just wondering if I got to go as far as swapping wires too.

i could have sworn the 750 from YK t0 03 where exactly the same, are you shure you didnt pick up an 04/05 by mistake?

I agree with Zeebo, the OEM microfiche shows the same part number for the harness for 00-03 GSXR 750. If in doubt, pull the old harness and install the new one. Once the motor is out, there is minimal extra work to pull the rest of the harness.
