oxygen available for combustionIn low elevations and cold temperatures, the air is more dense and has more oxygenIn higher
elevations and higher temperatures, the air is less dense with reduced oxygenPolaris ATV Carburetors are calibrated for an
altitude of 0-6000 ft(0-1800 meters) and ambient temperatures between +40 and +80 (+5 to +26 C)Carburetors must be re-calibrated
if operated outside this temperature andor altitude rangeThe jetting installed in production is not intended for all altitudes
