MAINTENANCE
Spark Plug Service
1. Remove spark plug high tension lead (A). Clean plug area
so no dirt and debris can fall into engine when plug is
removed.
2. Remove spark plug (B).
3. Inspect electrodes for wear and carbon buildup. Look for
a sharp outer edge with no rounding or erosion of the
electrodes.
4. Clean with electrical contact cleaner or a glass bead spark
plug cleaner only. CAUTION: A wire brush or coated
abrasive should not be used.
5. Measure gap with a wire gauge. Refer to specifications in
picture below for proper spark plug type and gap. Adjust
gap if necessary by bending the side electrode carefully.
6. If necessary, replace spark plug with proper type.
CAUTION: Severe engine damage may occur if the
incorrect spark plug is used.
7. Apply a small amount of anti-seize compound to the spark
plug threads.
8. Install spark plug and torque to specification
Engine To Frame Ground
Inspect engine ground cable connection. Be sure it is clean and
tight. The ground cable runs from the engine to the terminal
block located under the front hood next to the battery.
STEERING AND SUSPENSION
Steering
The steering components should be checked periodically for
loose fasteners, worn tie rod ends, and damage. Also check to
make sure all cotter pins are in place. If cotter pins are removed,
they must not be re-used. Always use new cotter pins.
Replace any worn or damaged steering components. Steering
should move freely through entire range of travel without
binding. Check routing of all cables, hoses, and wiring to be
sure the steering mechanism is not restricted or limited.
NOTE: Whenever steering components are
replaced, check front end alignment. Use only
genuine Polaris parts.
