What other year motors fit in 2002 kx125?

Put a KX250 motor into a 2002 kx125 frame?

Just a curious question. I love my 125 for everything it is, but I'd like more roost power. :aj: So, is it a conversion that has been done succesfully, easily? Or is in the realm of "possible, but difficult and not worth the trouble."??

Another question. I am shopping for a spare engine for my 2002 kx125 and I would like to know what other years of kx 125 motors will fit in my chassis?
Thanx Guys,
