I hear you can simply swap the 300 cylinder and piston over, but if the stroke is different, I think that would mess with either the compression or port timing, or both and you would need to change the crank too. No personal experience though.

One of the dirt mags just commented about one that they rode in a custom offroad bike test and said it was the best 300 they ever rode. different stroke made it a better 300...
the 250 and 300 share the same stroke, have since 2004

I also rode the 2009 250XC w/ the 300 cylinder that won the Dirt Rider shootout as that is my local dealer and I'm friends w/ those guys. It definitely didn't have the pep of mine but of course it was set up for Hare Scramble and so it had the auto-clutch and some other stuff that made it less responsive than mine. Very nice bike however.
