Kawasaki KX65 Motorcycle User Manual

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.

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).
Operation with a n improperly adjusted, incorrectly
routed, or damaged cable could result in an unsafe
riding condition.
