CARBURETOR
CABLE ADJUSTMENT
1WARNING
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 inter-
ference. Anything interfering with carburetor operation
may cause loss of vehicle control and personal injury.
Check throttle cable adjustment:
● Before every ride.
● At every scheduled service interval.
Check throttle cable adjustment with engine running. Turn
handlebars through full range of travel. If engine speed
changes during this maneuver, adjust throttle cables as fol-
lows:
1. Remove air cleaner. See AIR CLEANER, REMOVAL in
Section 4.
2. See Figure 1-41. Slide rubber boot (4) off cable
adjusters (3).
3. Loosen jam nut on each adjuster.
NOTE
Cable adjusters (3) and jam nuts are metric.
4. Turn adjusters in direction which will shorten cable hous-
ings to minimum length.
5. Point front wheel straight ahead. Twist throttle control grip
to fully open position; hold in position.
6. Turn adjuster (3) on throttle control cable (1) until throttle
cam stop (5) touches carburetor stop plate (6). Tighten
jam nut on throttle control cable (1) adjuster (3); release
throttle control grip.
7. Turn handlebars fully to right. Turn adjuster (3) on idle
control cable (2) until end of cable housing just touches
the carburetor cable guide.
8. Twist and release throttle control grip a few times. Carbu-
retor throttle must return to idle position each time throt-
tle grip is released. If this is not the case, turn adjuster (3)
on idle control cable (2) (shortening cable housing) until
throttle control functions properly.
9. Tighten jam nut on idle control cable (2) adjuster (3).
Recheck operation of throttle control (Step 7).
10. Slide rubber boot (4) over each cable adjuster (3).
Recheck engine slow idle speed; adjust if required.
11. Install air cleaner. See AIR CLEANER, INSTALLATION
in Section 4.
IDLE ADJUSTMENT
Check idle adjustment:
● Before every ride.
● At every scheduled service interval.
