Alright I have a CBR F2 and need a engine for it and have no luck so I'm thinking about buying and F3 engine but my questions are will it match up with my wiring harness? Will I need to also get the F3 carbs to fit it? And how about the air housing? Also then I would ned the F3 gauges to go along with the motor so the gauges will work correct? I appreciate any input I get back. Thanks

 

Also a F4 if possible?

 

All I know is that the F3 motor is almost identical to the F2 motor. I doubt the F4 motor would work without modification.

 

I didnt figure the F4 would fit. But im curious on the F3 specifics and details on it.
