MAINTENANCE
Spark Plugs
A new engine can cause temporary spark plug fouling due to the preser-
vative added during the assembly process. Avoid prolonged idle speeds,
which cause plug fouling and carbonization.
Refer to your Owner's Manual Supplement for the specific spark plug to
be used in your machine.
Change the spark plugs every 2000-2500 miles (3200-4000 km).
CAUTION
Using non-recommended spark plugs can result in serious engine damage.
A spark plug with a heat range too high will always cause engine damage if
the engine is operated in conditions more severe than intended for that plug.
Always use the spark plugs recommended for your snowmobile. See your
Owner’s Manual Supplement.
• Use recommended spark plugs with the proper gap.
• Use only resistor-type spark plugs.
• Torque spark plugs to 18-22 ft. lbs. (24-30 Nm).
• Always carry spare spark plugs.
