5-9 Pre Operation Checks
Throttle Freeplay
If the throttle pedal has excessive play due to
cable stretch or mis-adjustment, 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, Adjust the
freeplay if necessary.
Throttle Freeplay Inspection
1. Set parking brake
2. Start the engine. Allow engine to warm up a
few minutes
3. Measure the distance the throttle pedal
moves before the engine begins to pick up
speed. Freeplay should 1/16 to 1/8 inches
(1.5-3mm).
Throttle Freeplay Adjustment
1. Remove seat.
2. Loosen the throttle cable column nut.
Adjust the throttle cable so the throttle pedal
freeplay is 1/16 to 1/8 inches (1.5-3mm).
1．Throttle Cable column nut
3. Tighten the Throttle Cable column nut.
