EMISSION CONTROL INFORMATION
To protect the environment in which we all live, Kawasaki has incorporated crankcase emission (1) and exhaust emission
(2) control systems (EM) in compliance with applicable regulations of the United States Environmental Protection Agency
and California Air Resources Board.
1.
Crankcase Emission Control System
A sealed-type crankcase emission control system is used to eliminate blow-by gases. The blow-by
gases are led to the breather chamber through the crankcase. Then, it is led to the air cleaner.
Oil is separated from the gases while passing through the inside of the breather chamber from the
crankcase, and then returned back to the bottom of crankcase.
2. Exhaust Emission Control System
The exhaust emission control system applied to this engine consists of a carburetor and an ignition
system having optimum ignition timing characteristics.
The carburetor has been calibrated to provide lean air/fuel mixture characteristics and optimum fuel
economy with a suitable air cleaner and exhaust system.
TAMPERING WITH EMISSION CONTROL SYSTEM PROHIBITED
Federal law and California State law prohibits the following acts or the causing thereof: (1) the removal or rendering
inoperative by any person other than for purposes of maintenance, repair, or replacement, of any device or element of
design incorporated into any new engine for the purpose of emission control prior to its sale or delivery to the ultimate
purchaser or while it is in use, or (2) the use of the engine after such device or element of design has been removed or
rendered inoperative by any person.
Among those acts presumed to constitute tampering are the acts listed below:
Do not tamper with the original emission related part:
Carburetor and internal parts
Spark plugs
Magneto or electronic ignition system
Fuel lter element
Air cleaner elements
Crankcase
Cylinder heads
Breather chamber and internal parts
Intake pipe and tube
