WARNING
Throttle cables must not pull tight when handlebars are
turned fully to left or right fork stops. Be sure wires and
throttle cables are clear of fork stops at steering head so
they will not be pinched when fork is turned against
stops. Steering must be smooth and free with no binding
or interference. Anything interfering with steering sys-
tem operation may cause loss of vehicle control, which
could result in death or serious injury.
Check throttle cable adjustment:
●
Before every ride.
●
At every scheduled service interval.
With engine running, turn handlebars through full range of
travel. If engine speed changes during this maneuver, turn
engine OFF and adjust throttle cables as follows:
1. Remove airbox and baseplate. See 4.43 AIRBOX .
2. See Figure 1-40. Loosen cable adjuster lock (5) on each
.
3. Turn adjusters (4) in direction which will shorten cable
housings to minimum length.
4. Point front wheel straight ahead. Twist throttle control
grip to fully open position; hold in position.
5. Turn adjuster on throttle control cable (2) until throttle
cam stop touches stop plate. Tighten cable adjuster lock
on throttle control cable adjuster; release throttle control
grip.
6. Turn handlebars fully to right. Turn adjuster on idle con-
trol cable (3) until end of cable housing just touches the
cable guide.
7. Twist and release throttle control grip a few times. Throt-
tle plate must return to idle position each time throttle
grip is released. If this is not the case, turn adjuster on
idle control cable (shortening cable housing) until throttle
control functions properly.
8. Tighten cable adjuster lock on idle control cable.
Recheck operation of throttle control.
9. Recheck engine slow idle speed; adjust if required.
10. Install airbox, baseplate and intake cover assembly. See
4.43 AIRBOX .
IDLE SPEED
Check engine idle speed and adjust as required:
● At every 1000 mile (1600 km) service interval.
● At every 5000 miles (8000 km) service interval thereafter.
Regular idle speed is 1050-1100 RPM. Set idle speed using
idle adjuster shown in
Figure 1-41. Turn adjuster clockwise to
increase idle speed or counterclockwise to decrease idle
speed.
