9. Turn the heat off and watch the continuity as the
temperature decreases.
a. While the temperature is above 12
±
4° C (53
±
7° F), there should be no continuity be-
tween the switch terminals.
b. When the temperature drops below 12
±
4° C
(53
±
7° F), there should be continuity be-
tween the switch terminals.
10. Replace the thermo switch if the test results are
not within the above specifications.
Carburetor Heater Test
1. Disconnect the electrical lead from the carbure-
tor heater and remove the heater from the carbure-
tor.
2. When using an analog ohmmeter, set it to the R ×
1 scale.
3. Connect an ohmmeter to the carburetor heater as
shown in
Figure 82
and check the heater’s resis-
tance.
4. Replace the carburetor heater if the resistance is
not within the range specified in
Table 2
.
THROTTLE CABLE
Replacement
1. Securely support the motorcycle on a level sur-
face.
2. Remove the fuel tank, air filter housing and
surge tank as described in this chapter.
3. Remove the frame neck covers (Chapter Four-
teen).
4. Note how the throttle cables are routed along the
left side and through the fork legs. The new cable
must be rerouted along the same path.
5. Loosen the pull cable locknut (A,
Figure 83
)
and the return cable locknut (B). Release each cable
from the carburetor bracket and disconnect the ca-
ble ends from the throttle wheel. If necessary, turn
the pull cable adjuster (C,
Figure 83
) to create addi-
tional slack.
6. Remove the front brake master cylinder (Chap-
ter Thirteen).
7. Remove the mounting screws (
Figure 84
) and
separate the halves of the right handlebar switch as-
sembly.
8. Disengage the ends (A,
Figure 85
) of both the
pull and return cables from the throttle grip. Re-
move each cable from the handlebar switch hous-
ing.
9. Release the cables from any ties or holders (
Fig-
ure 86
) that secure them in place. The ties or holder
must be reinstalled in their original locations.
