READ THIS FIRST
For your safety, read this Owner's Manual and understand it thoroughly before operating this ENGINE.
DANGER
Exhaust gas contains carbon monoxide, a colorless, odorless poisonous gas. Inhaling carbon monoxide can cause serious brain injury or death. DO NOT run the engine in enclosed areas. Operate only in a well-ventilated area. Gasoline is extremely flammable and can be explosive under certain
conditions, creating the potential for serious burns. When refueling, servicing fuel system, draining
gasoline and/or adjusting the carburetor: Stop engine and allow it to cool before refueling. DO NOT
smoke. Make sure the area is well-ventilated and free from any source of flame or sparks, including
the pilot light of any appliance. DO NOT fill the tank so the fuel level rises into the filler neck or level
surface of level gauge. If the tank is overfilled, heat may cause the fuel to expand and overflow
through the vents in the tank cap. Wipe off any spilled gasoline immediately. Engines can become
extremely hot during normal operation. To prevent fire hazard: Keep the engine at least 1 m (3.3 ft)
away from buildings, obstructions and other flammable objects. DO NOT place flammable objects
close to the engine. DO NOT expose combustible materials to the engine exhaust. DO NOT use the
engine on any forest covered, brush covered or grass covered unimproved land unless spark arrester is installed on the muffler. To avoid getting an electric shock, DO NOT touch spark plugs, plug
caps or spark plug leads during engine running. To avoid a serious burn, DO NOT touch a hot engine
or muffler. The engine becomes hot during operation. Before you service or remove parts, stop engine and allow the engine to cool. DO NOT place hands or feet near moving or rotating parts. Place a
protective cover over pulley, V belt or coupling. DO NOT run engine at excessive speeds. This may
result in injury. Always remove the spark plug caps from spark plugs when servicing the engine to
prevent accidental starting.
Read warning labels which are on the engine and understand them. If any label is missing, damaged, or
worn, get a replacement from an authorized Kawasaki engine dealer and install it in the correct position.

EMISSION CONTROL INFORMATION
Fuel Information
THIS ENGINE IS CERTIFIED TO OPERATE ON UNLEADED REGULAR GRADE GASOLINE ONLY. A minimum of 87 octane of the antiknock index is recommended. The antiknock index is posted on service station
pumps in the U.S.A.
Emission Control Information
To protect the environment in which we all live, Kawasaki has incorporated an exhaust emission control system in compliance with applicable regulations of the United States Environmental Protection Agency (EPA). Also, depending on when your engine was produced, it may have an assigned emissions durability period.
* See below for the engine emissions durability period that may apply to your engine.
Exhaust Emission Control System
The exhaust emission control system applied to this engine consists of a fuel system and an Electronic Fuel
Injection (EFI) system having optimum ignition timing characteristics. The EFI system has been calibrated to
provide lean air/fuel mixture characteristics and optimum fuel economy with a suitable air cleaner and exhaust
system.
A sealed-type crankcase emission control system is also used to eliminate blow-by gasses. The blow-by
gasses are led to a breather chamber through the crankcase and from there to the air cleaner.
Engine Emissions Compliance Period
Engines Greater Than or Equal To 225 cc
Durability Period – 1,000 hours
★If your engine has an assigned emissions durability period it will be located on the certification label
attached to the engine (IMPORTANT ENGINE INFORMATION).
High Altitude Performance Adjustment Information
Engine models with fuel injection do not require high altitude performance adjustment.
Black plate (6,1)
