Side Stand
To install the side stand, insert its flat end into the rear axle as shown in the figure.
A. Side Stand
B. Rear Axle
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.
NOTE
○
Support the motorcycle with a suitable stand to perform maintenance or adjustment procedures.
Fuel
Fuel Requirements:
Your Kawasaki engine is designed to use only unleaded gasoline with a minimum octane rating shown below. Never use gasoline with an octane rating lower than the minimum specified by Kawasaki to prevent severe engine damage.
The octane rating of a gasoline is a measure of its resistance to detonation or “ knocking ” . The term commonly used to describe a gasoline
’ s octane rating is the Research Octane Number (RON).
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 unsatisfactory performance.
Fuel Type and Octane Rating
Use clean, fresh unleaded gasoline and an octane rating equal to or higher than that shown in the table.
Black plate (23,1)
GENERAL INFORMATION 23
Fuel Type Unleaded Gasoline
Ethanol Content E10 or less

NOTICE
Do not use any fuel that contains more ethanol or other oxygenates than specified for
E10 fuel* in this vehicle. Damage to the engine and fuel system, or engine starting and/or performance problems may result from the use of improper fuel.
*E10 means fuel containing up to 10% ethanol as specified by European directive.
Filling the Tank:
This Kawasaki KX has a 4-stroke engine that requires a gasoline.
The capacity of the fuel tank is 6.2 L (1.6 US gal).
To open the fuel tank cap, pull out the breather hose from the hole in the steering stem, and turn the tank cap counterclockwise.
A. Fuel Tank Cap
B. Breather Hose
Avoid filling the tank in the rain or where heavy dust is blowing so that the fuel does not get contaminated.

Black plate (24,1)
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.
NOTICE
Certain ingredients in gasoline may cause paint fading or damage. Be extra careful not to spill fuel during refueling.

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.
A. Kick Pedal
GENERAL INFORMATION 25
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.
Black plate (26,1)
26 GENERAL INFORMATION
When engine is cold •
Pull out the idle adjusting screw/choke knob.
When engine is already warm or restarts •
Kick the engine over, leaving the throttle closed without using the idle adjusting screw/choke knob.
NOTE
○
If the engine fails starting, open the throttle fully and depress the kick pedal slowly about 4 ~ 5 times to clear too rich fuel mixtures in the engine.
Then, kick the engine over, leaving the throttle closed.
A. Idle Adjusting Screw/Choke Knob
•
Find the kick pedal position around the top so that the resistance to depress the kick pedal is fully felt by pushing down the kick pedal slowly.
•
Kick the engine over, leaving the throttle closed.
NOTE
○
When the clutch lever is pulled, the motorcycle can be started with the transmission in any gear.
•
Even after the engine has started, do not push back immediately the idle adjusting screw/choke knob until the engine is thoroughly warmed up.
Black plate (27,1)
Launch Control Mode
The launch control mode can be used to adjust ignition timing to help riders get better starts on slippery terrain.
The system's effectiveness is dependent on rider skill, technique and terrain conditions.
Launch Control Mode Setting
•
The launch control mode can be set when the engine is running and in neutral, 1st or 2nd gear.
When activated, it only functions in 1st and 2nd gear.
•
When pushing the launch control mode button for over two seconds, the orange launch control mode indicator light will blink to indicate the system is operating.

•
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.
A. Connector
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.

Break-In
A brief break-in procedure must be carried out to obtain the proper operating clearances in the engine and transmission, which are necessary for performance and reliability.
NOTICE
For the first hour or 20 km (12 mile) of operation, run the engine at low and moderate engine speeds. See details below.
Break in the engine as follows.
1. Start the engine and let it idle until it is thoroughly warmed up.
2. Ride the motorcycle for about 20 minutes within
1/2 throttle opening.
3. Stop and let the engine cool completely. Be sure to check the tightness of nuts and bolts, oil leakage, coolant leakage and any irregularities.
4. Start the engine and ride the motorcycle for about 40 minutes within 3/4 throttle opening.
5. Stop and let the engine cool completely. Be sure to fully check the tightness of nuts and bolts, oil leakage, and any irregularities, especially, each cable elongation, brake play, chain slack and spoke tightness.
6. Change the engine oil, oil filter and front fork/rear shock absorber oil to the new one.
7. After the break-in procedure has been properly carried out, the motorcycle is ready for regular operation. Using the proper riding skills and
Black plate (31,1)
GENERAL INFORMATION 31 techniques and avoiding recklessly high engine speeds will keep the engine trouble-free.
NOTICE
When any following parts have been replaced, the same break-in procedure as the new motorcycle must be carried out for one hour or 20 km (12 mile):
Cylinder, Piston, Piston pin, Piston ring,
Valve, Valve lifter, Camshaft, Crankshaft, Mission gear, etc.
