hi, i have a KX 125cc 2002 and the engine is extreamly broken and i need a new one i was just woundering if a newer engine would fit the frame and run correctly. If so where could i buy one from a 2002 engine or later.
Thanks...

 

welcome to KF. try posting in the KX section too.

 

It would be cheaper to sell as "nice, doen't run", for $1100. Then buy another 02 for $1400. That's my take on it. Good luck.
