will a 2005 600RR engine fit into an 03? just wondering, doing a swap cuz I fried my bearings.
what about the wiring harness? if i use the 05 ecu can i still use the 03 harness? just wonderingmaskale said:You may want to change your ECU also, the ports are different, so your fuel requirments will be different, although a PC and a custom map may solve that for you.
