NOTICE: Using non-recommended spark plugs can result in serious engine
damage. Use POLARIS-recommended spark plugs or their
equivalent. See page 92.
Spark plug condition is indicative of engine operation. The spark plug
firing end condition should be read after the engine is warmed up and
the vehicle is driven at higher speeds. Immediately check the spark plug
for correct color. See page 65.
A hot exhaust system and engine can cause burns. Wear protective
gloves when removing a spark plug for inspection.

Spark Plug Condition

Normal Plug
The normal insulator tip is gray, tan or light brown. There will be few
combustion deposits. The electrodes are not burned or eroded. This
indicates the proper type and heat range for the engine and the service.
Tip: The tip should not be white. A white insulator tip indicates overheating,
caused by use of an improper spark plug or incorrect throttle body
adjustments.
Wet Fouled Plug
The wet fouled insulator tip is black. A damp oil film covers the firing
end. There may be a carbon layer over the entire nose. Generally, the
electrodes are not worn. General causes of fouling are excessive oil, use
of non-recommended injection oil or incorrect throttle body
adjustments.
Spark Plug Removal and Replacement
1. Remove the spark plug cap.
2. Using the spark plug wrench provided
in the tool kit, remove the plug by
rotating it counter-clockwise.
3. Reverse the procedure for spark plug
installation. Torque to specification.
