Need Help with High Elevation Jetting

Hello, I live in Delaware and I ride between sea level and about 2000 ft. at Tower City PA. This August however I'm going to Crested Butte, CO to ride for a few days with a friend from Aspen. My friend tells me that we will be between 8000 ft. and 12000 ft.. I have an 01 YZ 426 with stock jetting.

Do any of you ride at these altitudes, and if so, can you help me with what jetting to run?

Thanks a lot.

John
