I'm new to the crf250r and trying to wrap my head around everything. I just picked up a 2009 crf250r and I'm doing a complete rebuild and need a complete head (and cam). Can anyone explain the differences between the three years? My understanding is the 08 and 09 are the same?

I'd assume since there is a price difference between the 08 and 09 there is some changes here? Since I need a new cam I'm not limited to years due to cam changes (if there are any).
