hey guys

i bought a yz80 rolling chassi to make a mini motard, i have been going to the track on my nsr50 but i am too heavy for it, now before i buy a yz80 motor, i was wondering if i could fit a yz125 or rm 125. i know anything is possible but i was wondering what it would take ( i do not mind cuting and welding). if anyone have done it please let me know.


thanks for the help
