FEATURES AND CONTROLS
Polaris DRAGON Ignition System
Your snowmobile is equipped with an ignition system feature that
improves competition performance by increasing exhaust system
temperature. The DRAGON Ignition System provides maximum
“holeshot” performance for racing applications.
WARNING
DRAGON mode increases the exhaust system temperature and
causes engine misfire and backfire. Flammable materials and
vapors may ignite and result in fire and explosion, which may
cause serious injury, death or property damage. Read the
Owner’s Manual. Always follow all instructions and warnings.
DRAGON Mode Facts

closed courses by experienced riders only.

There is no benefit to using DRAGON mode for normal trail riding.

Unnecessary, extended or excessive use of DRAGON mode can re-
sult in severe engine damage, which is excluded from Polaris war-
ranty coverage.
S
DRAGON mode usually heats up the exhaust system within 5 to 20
seconds, depending upon the initial temperature of the exhaust sys-
tem.
S
Two different sounds may be heard when using DRAGON mode.
One sound is an erratic misfire that may be heard when the exhaust
system is heating up. The other sound is a consistent misfire (with a
slight rise in engine RPM) when the exhaust system is at target oper-
ating temperature.
S
DRAGON mode maintains the engine speed between 4500 and 5100
RPM.
S
Be sure that the clutch engages at 5300 RPM or above to prevent
forward creep of the vehicle. See your dealer if the clutch needs ad-
justment.
S
Please refer to the Polaris jetting chart and use the recommended jet
for current temperatures as this system is sensitive to jet changes.
