Operators Manual

CARBURETOR CALIBRATION

The standard carburetor calibration is for an ambient temperature of 25 °C / 77 °F and
400 m / 1310 ft above sea level. At operation with different temperatures and altitudes, the
main jet of the carburetor has to be changed in accordance with Table 1, to optimize en-
gine performance.
NOTE
For 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 by BRP-Rotax will no longer apply, if the carburetor calibration is
carried out improperly and causes engine damage.
The following application for smartphones shows the individual setting of your ROTAX®
125 Max DD2 evo engine:
The ROTAX® Max Jetting Guide is an App for Android™ and iOS devices, designed to as-
sist users with setting up the recommended main jet based on the ambient conditions and
the type of engine. The perfect set-up can be calculated in two ways, either automatically
- which requires a GPS signal and an internet connection, or manually - which requires
certain knowledge about altitude and weather conditions.
