Fuel Requirements
Fuel Type
Use clean, fresh unleaded gasoline with a minimum Antiknock index of 87. The Antiknock Index is posted on service station pumps in the U.S.A. The octane rating of a gasoline is a measure of its re-
sistance to detonation or “knocking.” The Antiknock Index is an average of the Research Octane Number (RON) and the Motor Octane Number (MON) as shown in the table below.
NOTICE
If engine “knocking” or “pinging” occurs, use a different brand of gasoline of a higher octane rating. If this condition is allowed to continue it can lead to severe engine damage. Gasoline quality is important. Fuels of low quality or not meeting standard industry specifications may result in unsatisfac tory performance. that result from the use of poor quality or non-recommended fuel may not be covered under your warranty.

Fuels Containing Oxygenates
Gasoline frequently contains oxygenates (alcohols and ethers) especially in areas of the U.S. and Canada which are required to sell such reformu lated fuels as part of a strategy to reduce exhaust emissions. The types and volume of fuel oxygenates ap- proved for use in unleaded gasoline by the U.S. Environmental Protection Agency include a broad range of alcohols and ethers, but only two compo nents have seen any significant level of commercial use. Gasoline/Alcohol Blends Gasoline containing up to 10% ethanol (alcohol produced from agricultural products such as corn), also known as “gasohol” is approved for use.
NOTICE
Avoid using blends of unleaded gasoline and methanol (wood alcohol) whenever possible, and never use “gasohol” containing more than 5% methanol. Fuel system damage and performance problems may result.
Gasoline/Ether Blends- The most common ether is methyl tertiary butyl ether (MTBE). You may use gasoline containing up to 15% MTBE.
NOTE
Other oxygenates approved for use in unleaded gasoline include TAME (up to 16.7%) and ETBE (up to 17.2%). Fuel containing these oxygenates can also be used in your Kawasaki.
NOTICE
Never use gasoline with an octane rating lower than the minimum specified by Kawasaki. Never use “gasohol” with more than 10% ethanol, or more than 5% methanol. Gaso line containing methanol must also be blended with inhibitors. cosolvents and corrosion Certain ingredients of gasoline may cause paint fading or damage. not to spill gasoline or gasoline oxygenate blends during refueling. When not operating your Kawasaki for 30 to 60 days, mix a fuel stabilizer (such as STA-BIL) with the gasoline in the fuel tank. Fuel stabilizer additives inhibit oxidation of Be extra careful the fuel which minimizes gummy deposits. Never store this product with “gasohol” in the fuel system. Before storage it is recommended that you drain all fuel from the fuel system. See the Storage section in this manual.
