4.1. Carburetor calibration
The standard carburetor calibration is set for an ambient temperature of 25 °C / 77 °F and 400 m /
1310 ft above sea level. For an operation at different temperatures and altitudes, the main jet of the
carburetor has to be changed to optimize engine performance.
¿ Note: For an engine operation at an ambient temperature below 10 °C / 50 °F, make sure
not to demand full power before the coolant temperature has reached 45 °C / 113
°F.
¿ Note: The warranty granted by BRP-Rotax will no longer apply, if the carburetor calibration
is carried out improperly and therefore causes engine damage.
