I'm living in CO @9000ft. I mostly ride between 8000 and 11,000ft. I have tried a little bit of all combinations of jetting. I just got my bike back from the shop and it was set up with a 45pilot; 3rd clip;180 main. I'm taking for a ride later but it seems to me thats extremely rich ,especially for summer in the Rockies. Whats working for you ?
