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. 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 carburetor and an ignition 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 specific air/fuel mixture  characteristics and optimum fuel economy with a suitable air cleaner and exhaust 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.
    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 Emission Compliance Period
    Engines Greater Than or Equal To 225 cc Model Year – 2011 and later
    Durability Period – 1 000 hours (Category A)

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
To improve the EMISSIONS CONTROL PERFORMANCE of engines operated above 1000 meters (3300 feet), Kawasaki requires the following Environmental Protection Agency (EPA) approved modifications.
High altitude adjustment requires replacement of carburetor main jets. Installation of these optional parts may be performed by an authorized Kawasaki engine dealer or  equally qualified service facility, or the consumer, following repair recommendations specified in the appropriate Kawasaki Service document or parts catalog.
Operating with the wrong configuration at a given altitude may increase its emissions and decrease fuel efficiency and performance.

FUEL AND OIL RECOMMENDATIONS

Fuel
Use only clean, fresh, unleaded regular grade gasoline.
CAUTION
Do not mix oil with gasoline.

Octane Rating
The octane rating of a gasoline is a measure of its resistance to “knocking”. Using a minimum of 87 octane by the antiknock index is recommended. The antiknock index is  posted on service station pumps in the U.S.A.

NOTE
○If “knocking or “pinging” occurs, use a different brand of gasoline or higher octane rating.
Oxygenated Fuel
Oxygenates (either ethanol or MTBE) are added to the gasoline. If you use the oxygenates, be sure it is unleaded and meets the minimum octane rating requirement.
The followings are the EPA approved percentages of fuel oxygenates.
ETHANOL: (Ethyl or Grain Alcohol)
You may use gasoline containing up to 10% 0ethanol by volume.
MTBE: (Methyl Tertiary Butyl Ether)
You may use gasoline containing up to 15% MTBE by volume.
METHANOL: (Methyl or Wood Alcohol)
You may use gasoline containing up to 5% methanol by volume, as long as it also contains solvents and corrosion inhibitors to protect the fuel system. Gasoline containing  more than 5% methanol by volume may cause starting and/or performance problems.
It may also damage
