ADJUSTING
THE THROTTLE CONTROL
Carefully read p. 55 (MAINTENANCE).
If the throttle sticks open, you will lose
control of your vehicle and a serious
accident could result.
If any fastener in the throttle system
becomes loose, likewise you will lose
control of your vehicle.
Either situation can lead to an upset or
collision with subsequent serious injury
or death.
The play of the throttle cable must be
between
0.08 – 0.12 in (2 – 3 mm) ,
measured at the edge of the grip, see the
illustration above.
To adjust the cable:
♦
Place the vehicle on the center stand.
♦ Pull back the rubber boot (1).
♦ Loosen the lock nut (2).
♦
Rotate the adjuster (3) in such a way as to
restore the prescribed value.
♦ After the adjustment, tighten the lock nut
(2) and check the play again.
♦
Replace the rubber boot (1).
Exhaust gases contain carbon monoxide,
which is extremely poisonous if inhaled.
Do not start the engine in closed or badly-
ventilated rooms.
Failure to observe this warning may cau-
se loss of consciousness or even lead to
death by asphyxia.
After you have adjusted the throttle, rota-
te the handlebars full left and full right with
the engine idling. Check to ensure that the
idle sound is not affected by this. Also
check that the throttle smoothly and fully
closes when released.
