MAINTENANCE

Throttle System

WARNING
Failure to check or maintain proper operation of the throttle system can result in an accident and lead to
serious injury or death if the throttle pedal sticks during operation.
Always check the pedal for free movement and return before starting the engine and occasionally
during operation. Never start or operate this vehicle if it has a sticking or improperly operating throttle
pedal. Immediately contact your dealer for service if throttle problems arise.

Throttle Freeplay

If the throttle pedal has excessive play due to cable
stretch or misadjustment, it will cause a delay in
throttle response, especially at low engine speed.
The throttle may also not open fully. If the throttle
pedal has no freeplay, the throttle may be hard to
control, and the idle speed may be erratic.
Check the throttle pedal freeplay at the intervals
outlined in the Periodic Maintenance Chart
beginning on page 52. Adjust the freeplay if
necessary.

Throttle Freeplay Inspection

1. Place the transmission in PARK.
2. 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 (1.6-3.2 mm).

Throttle Freeplay Adjustment

1. Remove the lower seat base.
2. Locate the throttle cable adjuster at the throttle body.
3. Slide the cable adjuster boot away from the adjuster.
4. Using a 10mm open-end wrench, loosen the adjustment jam nut.
5. Using an 8mm open-end wrench, move the cable adjuster until 1/16 to 1/8 inches (1.6-
3.2 mm) of freeplay is achieved at the throttle pedal.
Tip: While adjusting, lightly move the throttle pedal up and down.
6. Tighten the jam nut.
7. Apply a small amount of all-purpose grease to the inside of the boot and slide it over the
cable adjuster to its original position.
8. Reinstall the lower seat base.
9. Perform a test drive to ensure proper throttle operation.
