Fatmacrm250,

Here is a copy of a jetting chart that I had posted for the 02 RM250 about a month ago. This will give you a good head start towards getting your jetting dialed in for higher altitudes.

We just got back from riding the Idaho Dunes. When you get there go to Rexburg Motorsports. They can help you with the jetting. my YZ450F and my brothers CR450F went two sizes smaller on the jetting.
