To find an air cooled YZ125 engine and put it into a 1980 MX100 frame, The engine would have to be pretty old so i dont think it would cost that much. I was just wondering if anyone has ever tried or heard of someone trying to do this.

Should be easy to do with the possible exception of the intake and exhaust. You could also put the MX100 engine in the YZ125 frame. That might be even more fun!
