Kx 100/klx 140

Has any one put a KLX 140 motor in a KX 100? I have a 1999 KX 100 with a bad motor and can get a KLX 140 motor cheep. It's a bike that will be for 11 year old son.

I've never seen that done, but I've seen several people put older KLX125 engines in KX85/KX100 chasis. If you research some of those threads it should give you some ideas.

Thanks I will look.
