Fuel

This Kawasaki KX has a 4-stroke engine that requires a gasoline.

The capacity of the fuel tank is 6.1 L (1.6 US gal). To open the fuel tank cap, disconnect the breather hose from the hole in the steering stem, and turn the tank cap counterclockwise.

WARNING

Gasoline is extremely flammable and can be explosive under certain conditions. Always stop the engine and do not smoke. Make sure the area is well-ventilated and free from any source of flame or sparks; this includes any appliance with a pilot light. Never fill the tank so the fuel level rises into the filler neck. If the tank is overfilled, heat may cause the fuel to expand and overflow through the vents in the tank cap. After refueling, make sure the fuel tank cap is closed securely. If gasoline is spilled on the fuel tank, wipe it off immediately.

Fuel Requirement:

Fuel Type

Use clean, fresh unleaded gasoline with a minimum Antiknock Index of 90. 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 resistance 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.

GENERAL INFORMATION 21

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 reformulated fuels as part of a strategy to reduce exhaust emissions.

The types and volume of fuel oxygenates approved for use in unleaded gasoline by the U.S. Environmental Protection Agency include a broad range of alcohols and ethers, but only two components 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.

22 GENERAL INFORMATION

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. Gasoline containing methanol must also be blended with cosolvents and corrosion inhibitors.

Certain ingredients of gasoline may cause paint fading or damage. Be extra careful 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 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.

Kick Pedal

This motorcycle is equipped with a primary kick starting system. When the clutch lever is pulled, the motorcycle can be started with the transmission in any gear.

Starting the Engine

• Shift the transmission into neutral.

WARNING

Riding with the side stand can cause a crash resulting in injury. Do not start the engine or attempt to ride the motorcycle when the side stand is installed.

NOTICE

This motorcycle is designed for competition use only. Therefore, the radiator does not incorporate a coolant reserve tank or cooling fan. Prolonged idling of the engine with no airflow through the radiator can cause coolant loss and engine overheating resulting in possible engine damage. Any riding conditions that increase engine temperature will further reduce idling time before coolant loss occurs. These conditions include high ambient temperature, sandy or muddy terrain, or other conditions causing high engine loads at low speeds. Furthermore, warming the engine up excessively before operation, or leaving idling with the hot engine temperature after operation results in the engine overheating, too.

26 GENERAL INFORMATION

DFI Setting Data Selection

Three DFI settings are available to suit various track conditions. They are easily activated by changing the wiring connector on the side of the frame when the engine is stopped.

•Change the connector on the right front of the frame to suit the track condition with the engine stopped.

NOTE

○If the connector is changed while the engine is running, the DFI setting does not change.

○The ECU is set to the standard track condition when operated without a connector. However, always have one of the three connectors attached when riding to prevent dust and mud from accumulating in the connector harness.

○The KX FI calibration kit (Part No. 99999-0394) can be used for changing the DFI setting.

Shifting Gears

This motorcycle is equipped with a 5-speed “return shift” transmission. The neutral is located halfway between 1st and 2nd gear. “Return shift” means that when shifting up or down, each gear must be engaged before the next higher or lower gear may be selected.

•To engage first gear from the neutral position, pull in the clutch lever and push down on the shift pedal, gently release the clutch lever, then release the shift pedal.

•To shift up to the next gear, pull in the clutch lever, lift the shift pedal with your toes, gently release the clutch lever, and then release the shift pedal.

•To shift down to the next gear, pull in the clutch lever, push the shift pedal down as far as it will go, gently release the clutch lever, then release the shift pedal.

NOTICE

When changing gears, press firmly on the shift pedal to ensure proper shifting. Careless, incomplete shifting can cause the transmission to jump out of gear and lead to engine damage.

38 MAINTENANCE AND ADJUSTMENT

Engine Oil

WARNING

Motorcycle operation with insufficient, deteriorated, or contaminated engine oil will cause accelerated wear and may result in engine or transmission seizure, accident, and injury. Check the oil level before each ride and change the oil according to the periodic maintenance chart in the Owner’s Manual.

Because of the semi-dry sump lubrication system, the engine oil level indicated on the oil level inspection window will fluctuate depending on the motorcycle’s position and engine speed when the engine’s shut off. To ensure a proper reading of the engine oil level, follow the Oil Level Inspection procedures closely.

NOTICE

Racing the engine before the oil reaches every part can cause engine seizure.

Oil Level Inspection

•If the oil has just been changed, let the motorcycle sit a few minutes allowing the oil to settle.

•Start the engine and run it for several minutes at idle speed. Do not run the engine at high engine speed.

•Stop the engine and wait several minutes for the oil to settle.

•Check the engine oil level with the motorcycle vertical through the oil level inspection window on the lower right side of the engine. The oil level should come up between the high and low level lines next to the inspection window.

NOTE

○If the oil level is too high, remove the excess oil using a syringe or other suitable device.

○If the oil level is too low, add the correct amount of oil through the oil filler opening. Use oil of the same type and brand as those of the one that is already in the engine.

NOTE

○If no oil appears in the oil level inspection window, tip the motorcycle slightly to the right until oil is visible then return to an upright position. If no oil appears even when tipped at an extreme angle, remove the drain bolt to empty any oil that may be in the transmission and crankcase, reinstall the drain bolt and refill with the specified amount of oil.

Water Hoses

Check the water hoses for cracks or deterioration, and the connections for looseness in accordance with the Periodic Maintenance Chart.

Radiator

Check the radiator fins for obstruction by insects or mud. Clean off any obstructions with a low-pressure stream of water.

NOTICE

Using high-pressure water, as from a car wash facility, could damage the radiator fins and impair the radiator’s effectiveness.

Do not obstruct or deflect airflow by installing unauthorized accessories in front of the radiator.

Interference with the cooling airflow can lead to overheating and consequent engine damage.

Coolant

Coolant absorbs excessive heat from the engine and transfers it to the air through the radiator. If the coolant level becomes low, the engine overheats and may suffer severe damage. Check the coolant level each day before riding the motorcycle, and replenish coolant if the level is low.

MAINTENANCE AND ADJUSTMENT 43

WARNING

The cooling system can get extremely hot

during normal operation and cause serious j burns. Do not touch the radiator when it is

hot, nor open the radiator cap. Hot coolant inside will cause severe burns.

NOTE

○The coolant originally filled into the cooling system contains 50% of a permanent, ethylene-glycol -based antifreeze, has a freezing point of –35°C (–31°F) and a green appearance.
