has anyone put a newer model CR250 motor in their quad, did you have any problems, vibration, hard to install, how is the power delivery, do you like it better than a 250R engine?

 

I would not put a cr250 motor in a atv fram because it would vibrate like crazy. I have rode cr250's and they vibrate but think of it in a atv the vibration would be unbelible. I like the cr out put because it has a lot more bottom en becase of a power valve but i have not ridden a 250r with a power valve cylinder but i'm thinkin that they would be nice to have
