I haven't posted before and Sorry if this is a question asked alot, but I don't have time to search threads for the answer. I live at 4700 feet and trail ride in the mountains anywhere from 7 to 8000 feet. I just bought my bike this summer from a city across the state that is much lower in elevation. I took my jets out to see what they were and the main is 152 and pilot is 40. I don't know how to tell what the position the needle is in. It runs ok, but seems a bit rich and boggy. Does anybody have an idea what size jets I should be running at these elevations.
