is there a way that i can take the f4i fuel rail and ecu and hook it up to my f3 motor? i know there is a few sensor i would have to add but would it work?

 

I'm betting the engineering neccessary, would make it cheaper to fab different mounts and go to an f4i engine instead. Be an interesting project but not a cost-effective approach. imo.

I cant seem to find a complete motor and wiring harness in my area..not too big on parts biles or wtecked ones around here..

 

Technically its should not be a big deal but theres quite a bit of parts you'd need. Just off the top of my head...

Injectors,
Throttle bodies,
ECM,
Wire harness,
Airbox,
2/3 engine sensors,
Fuel pump.

The whole 'upgrade' was only good for about 5hp. You could throw a set of flatslides on there faster, easier and cheaper for the same or better gain IMO.

 

im kinda new to the bike world so sorry if this is a stupid question to ask....but...what is a set of flatsides?
