OK, I was just thinking, can a CR500 top-end be mated up with a 250R bottom end? I am pretty sure it can't be done, but I was just wondering, I have seen the "POLONDAS" or whatever they are. I have also seen a pilot topend on a 250R bottom end, and read something about a Cr500 top-end on a pilot bottom and, so is it possible to put a CR top-end on your 250R bottom end? Damn I used top-end and bottom end alot. If this is a really stupid question and you are just going to bash it don't reply!!! Thanks to anyone who replies.

 

WHAT A STUPID QUESTION !

J/K J/K I am almost positive it cannot be done. Most people dont waste there time and just put in the whole CR500 motor. I am not sure that the 250 bottom end would hold out with that much power.

 

I figured that. I was just wondering.
