Kawasaki KX65 Motorcycle User Manual


 
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).
