i just picked up a 95 F3 for $150 from my friend so i can use just for stunting. bike runs but may need a new motor soon cuz it sounds like the motor is grinding or something its hard to explain. motor has almost 50k on it, im gonna use the bike as is till it dies, but i wanted to see if anyone knows (not thinks) what motor i can swap into the bike without major modification if any at all. i can get a f2 motor for free with 12k but i dont know if i can swap it in. or could i throw in a f4 or f4i motor??? if anyone knows please let me know thanks.

 

i'm guessing a f4i wtih some fab work

 

f3 has a steel frame so any motor mount mods would be very easy and strong i know a guy who has an f3 with a gsxr 600 motor in it and a 900rr subframe with some other plastics and ****.......lol

 

use the f2 motor

 

thanks guys
