just wanted to know if a f3 motor can fit into a f2 bike??????

not without some modification. if youre going to go to the trouble to do a motor swap, go all out and do an f4i swap, 600rr swap or even go all out and shoehorn a 900rr motor in there. ive seen it done, but couldnt tell ya the thread i saw it in, this was quite some time ago. but yeah its going to take some modification and lots of work, youre better off trying to swap to something a little more extreme if youre going to go to the trouble.

A F3 motor will be the easiest swap by far. A 900RR motor will go, but you have to make/weld a lower motor mount to the frame down by the swingarm pivot. Ive never liked seeing this done because Of the heating of the steel frame near the swingarm pivot. But its been dont and apparantly is fine. Ive never heard or seen a FI bike put into a f2 or f3 frame. That my friend would be cool as hell!!!

I've heard all you have to do is notch the frame to allow for the TPS. That means you need the CDI box, and probably harness also. Sounds like a lot of work to me, but if you're up to it, it could be worth it.

yeah for sure a F4i motor will go in anything but, man thats some work!! Try the F4 motor. Carbed (so you wont have to mess with the box and wiring), and might "fit" decently!
