Just wondering, what other engines will fit in the f3 frame?

I am not looking to do this but i am just curious. Will a f2 engine fit in the f3 frame. What about an f4 or f4i engine, or even the 600rr engine. Will they fit in the f3 frame with little to no modification?

Anyone have any links of people who have put a different engine in their f3?

Thanks guy!

 

or even like other non-cbr engines. like a gsxr engine in my f3 cbr lol. Just wondering, i know it would not be worth it at all and better off just to buy a new bike. But i am just curious to see if anyone has done this, i know there has to be someone out there who has. Thanks again.

 

I know for a fact you can swap engines from earlier/later f models, my buddy next door has an f2 with an f3 engine in it. or maybe it was the other way around. one of those.

but he may have modified the frame i am not 100% on that

 

Yeah i have heard that you can put a 900rr cbr engine in it too with just modifying the front brackets i think. But i wanna see some pics or something about it.

 

lol sounds like a lot of work.

 

I'd imagine these old frames wouldn't be able to take the punishment from that lol

 

Yeah true man. I was just wondering, just looking to see whats up.
