Throttle Body Assy

Idle Speed Inspection

•
Refer to the Idle Speed Inspection in the Periodic Main-
tenance chapter.

Throttle Bore Cleaning

•
Check the throttle bore for cleanliness as follows.
○
Remove the throttle body assy (see Throttle Body Assy
Removal).
○
Check the throttle valve [A] and throttle bore [B] for carbon
deposit by opening the throttle valve.
If any carbon accumulates, wipe the carbon off the throttle
bore around the throttle bore and the throttle valve, using
a cotton pad penetrated with a high flash-point solvent.

Throttle Body Assy Removal

Gasoline is extremely flammable and can be explo-
sive under certain conditions, creating the potential
for serious burns. Make sure the area is well venti-
lated and free from any source of flame or sparks;
this includes any appliance with a pilot light. Do not
smoke. Turn the ignition switch off. Disconnect the
battery (–) terminal. To avoid fuel spills, draw it from
the tank when the engine is cold. Be prepared for
fuel spillage; any spilled fuel must be completely
wiped up immediately.
•
Remove:
Storage Box (see Storage Box Removal in the Frame
chapter)
Air Cleaner Box (see Air Cleaner Box Removal)
•
Loosen the throttle cable by the adjuster on the throttle
grip side (see Throttle Control System Inspection in the
Periodic Maintenance chapter).
•
Loosen the locknuts [A].
•
Remove the throttle cable lower ends [B] from the throttle
pulley.
•
Disconnect:
Throttle Sensor Connector [A]
Idle Speed Control Valve Actuator Connector [B]
Intake Air Pressure Sensor Connector [C]
•
Loosen the clamp screw [D].
•
Remove the throttle body assy [E].
•
After removing the throttle body assy, stuff pieces of lint
-free, clean cloths into the throttle body assy holders.
If dirt gets into the engine, excessive engine wear
and possible engine damage will occur.
