that^^

 

I don't know anyone that's attempted it. I would think that physically, yes it would fit, but there would be things that are missing due to the differences between the bikes. The first thing that comes to mind is the Throttle Position Sensor, which the F2 doesn't have. There is no Fuel Cut relay either, and the speedometer on an F3 is electronic, whereas the F2 is still mechanical. I'd say that it's not a good fit for sure.

 

^^ agreed

there are some electronic upgrades with wire harnesses. if ur using the f3 harness on the f2, i think u would be fine since the F2 has less like Idodirt said but yea. if ur using the f2 harness on the f3, i think u can do so safely as long as u wire in the TPS... fuel cut relay i think u can adapt to the wireharness tho... its gonna be a bit of a headache tho

speedo, i dunno how important it is 2 u but u can stick with the f2 speedo
