I'll try to make this as short as possible. I've been lurking on here for a long time and finally registered because of this question that i can't seem to find the answer to. I bought an 08 motor to put in a dragbike. It is a complete aftermarket chassis so nothing there. I want to run the gen I throttle bodies, for reasons in the future, and can't figure out what I need to make this happen. Do I go with the Gen I wiring harness and ecu? will the Gen I harness plug into the Gen II motor? Does the ECU need signals from things like the oil pressure switch, tip over sensor, etc? Does the fuel pump need a return line to the fuel tank? Thanks in advance for any help.
