I have a wr450 and my girl has a wr250 (2006).  I know there is a piston cooling jet modification on the 450 to add some more oil to the wrist pin and increase reliability. Is there a similar mod to the 250's?

I have never known piston longevity to be an issue with the 250. Not sure why you would need to do this.
