OPERATION

Carburetion

Jetting Guidelines

Changes in altitude and temperature affect air density, which is the

amount of oxygen available for combustion. In low elevations and cold

temperatures, the air has more oxygen. In higher elevations and higher

temperatures, the air is less dense.

All carburetors have been pre-set at the factory to the settings indicated

by the shaded cells of the jetting chart on page 105. Carburetors must be

re-calibrated if the snowmobile is operated outside this production

temperature and/or altitude range. The main jet installed in production is

not correct for all altitudes and/or temperatures. The number stamped in

the end of the main jet indicates the jet size that was installed at the time

of manufacture.

NOTICE: Using non-recommended jets and/or needles can result in shorter

engine life, lower fuel economy, increased emissions and poor

performance and drivability. Always use POLARIS-recommended jets

and needles.

It’s the owner’s responsibility to ensure that the correct jets are installed

in the snowmobile for a geographical area. Be very careful when jetting

down in warm weather. As the weather turns colder it will be necessary

to re-jet upward to prevent engine damage. When selecting the proper

main jet always use the lowest elevation and temperature that is likely to

be encountered.
