Throttle Pedal Freeplay Adjustment
NOTICE: Engine idle speed is established at the factory and is not adjustable.
Never attempt to adjust engine idle speed by adjusting throttle pedal
freeplay. At operating temperature, idle speed should be 1250 +/- 50
RPM. If engine idle speed is not satisfactory, please see your
POLARIS dealer.
1. Place the transmission in PARK.
2. Apply the brakes. Start the engine. Allow it to warm up thoroughly.
3. Measure the distance the throttle pedal moves before the engine
begins to pick up speed. Freeplay should be 1/16 to 1/8 inches (1.5-
3 mm).
4. Remove the seat. Remove
the engine access panel.
See page 28.
5. Locate the in-line throttle
cable adjuster near the
engine valve cover.
6. Slide the cable adjuster
boot off the cable
adjuster.
7. Loosen the adjustment
jam nut.
8. Rotate the cable adjuster until 1/16" to 1/8" (1.5-3 mm) of freeplay
is achieved at the throttle pedal. See page 109. While adjusting,
lightly flip the throttle pedal up and down.
9. Tighten the jam nut.
10. Apply a small amount of grease to the inside of the boot and slide it
over the cable adjuster to its original position.
