There aren't a whole lot of high elevation mappings in here so i'd like some expert opinions on jetting changes. Bike is an '04 with FMF exhaust, no emissions stuff. Driveway is 5,200ft. Typical rides are 4,000 - 8,000ft. Extreme elevations in NM are down toward 3K and up to 12-13K ft. Currently, the bike runs well with the following: Stock air box with pre-filter instead of snorkel Mains - 145/148 low spd - 42 IAMS - 2.5 turns (roughly) It was difficult to tell with the flex jets. IAJ 70/70 needles are NDFB on middle clip. So the third out of five settings. Floats are 3mm I am putting on the Triple Clamp Moto open air filter kit. After reading through here for quite a while, here's what I am thinking of switching to: Mains - 160/162 low spd - 42 IAMS - 2 turns IAJ - 70/70 needles are NDFB on middle clip. So the third out of five settings. Floats - 3.5mm Is there anything sticking out like a sore thumb with the proposed new settings or am I on the right track?
