Don,
I am not from CO but we were in the Colorado Springs area 2 weeks ago. Altitude 8,500 to 9,500 ft. I have a '01 200E/XC as well. Had it jetted as follows
Main 175 (go to 178 or 180 if riding wide open a lot)
Needle 1369N 3rd clip
Pilot 40
AS 1 1/2 out
Bike ran very well. My 200 does not seem to like the richer pilot that some people are using even at our low altitude in Illinois.
Hope this helps and have fun!
Tom
