d3ac0n Posted February 12, 2020 Report Share Posted February 12, 2020 Lets say Im riding at 4,000 ft above sea level and eveything is dialed in and running great. My air mixture screw on my keihin 35mm is at 1.5 turns. I then decide to ride at 2,000 ft above sea level, is it good practice to adjust the air mixture screws or leave them as is? When adjusting for lower elevation do you shoot for leaner air mixture ex: 2.5 turns out or a richer air mixture ex: 1 turn out? I'm aware that due to lower elevation it would be good to increase jet size but as far as air mixture screw im not sure what to tune towards.
