FUEL SYSTEM 2-7
Carburetor
Since the carburetor regulates and mixes the fuel and air
going to the engine, there are two general types of carbure-
tor trouble: too rich a mixture (too much fuel), and too lean
a mixture (too little fuel). Such trouble can be caused by
dirt, wear, maladjustment, or improper fuel level in the float
chamber. A dirty or damaged air cleaner can also alter the
fuel to air ratio.
Idle Speed Inspection
•
Start the engine and warm it up thoroughly.
•
With the engine idling, turn the handlebar to both sides.
If handlebar movement changes the idle speed, the throt-
tle cable may be improperly adjusted or incorrectly routed,
or it may be damaged. Be sure to correct any of these
conditions before riding (see Cable, Wire and Hose Rout-
ing in the General Information chapter).
WARNING
Operation with a n improperly adjusted, incorrectly
routed, or damaged cable could result in an unsafe
riding condition.
•
Check idle speed.
Adjust it as needed.
Idle Speed Adjustment
•
First turn in the air screw [A] until it seats lightly, and back
it out 2 turns (KX65-A1 ∼ A2).
•
First turn in the air screw [A] until it seats lightly, and back
out 1 1/2 turns (KX65-A3 ∼).
•
Start the engine and warm it up thoroughly.
•
Turn the idle adjusting screw [B] to obtain desired idle
speed. If no idle is preferred, turn out the screw until the
engine stops.
•
Open and close the throttle a few times to make sure that
the idle speed is as desired. Readjust if necessary.
Service Fuel Level Inspection
WARNING
Gasoline is extremely flammable and can be ex-
plosive under certain conditions. Always stop the
engine and do not smoke. Make sure the area is
well ventilated and free from any source of flame
or sparks; this includes any appliance with a pilot
light.
•
Turn the fuel tap to the OFF position.
•
Remove the fuel tank (see Fuel Tank Removal).
