Hey any of you Colorado guys, I'm going to ride the Colorado 500 and I want to know what jetting to use above 8000 feet on a 2003 WR450F. Thanks, Big Jim :) :D :D

Kewl, I'll be there too!!! My jetting is 155 main, 42 pilot, clip in the 4th position. I have had pretty good luck with this with my pipe opened up to about 10500. With my VOR tip in, it sucks. But from what I'm gathering that may be due to the VOR tip alone. I'm either going to get a FMF Q or a GYT insert by the 500.
