OPERATION AND IMPORTANT RIDING POINTS
1. Turn the main switch to “ON” and
the engine stop switch to “ ”.
ECA00005
CAUTION:
The warning light and fuel indicator
light should come on for a few sec-
onds and then go off. If an indicator
light does not go off, refer to the cor-
responding indicator light circuit
check in the “INSTRUMENT AND
CONTROL FUNCTIONS” section.
2. Shift the transmission into neutral.
NOTE:
When the transmission is in neutral, the
neutral indicator light should be on. If
the light does not come on, ask a
Yamaha dealer to inspect it.
3. Turn on the starter (choke) and
completely close the throttle grip.
4. Start the engine by pushing the
start switch.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt.5. After starting the engine, move
the starter (choke) to the halfway
position.
NOTE:
For maximum engine life, never accel-
erate hard with a cold engine!
6. After the engine is warm, turn off
the starter (choke) completely.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.
EAU01258
Starting a warm engine
The starter (choke) is not required
when the engine is warm.

EAU00423
Shifting
The transmission lets you control the
amount of power you have available at
a given speed for starting, accelerating,
climbing hills, etc. The use of the shift
pedal is shown in the illustration.
To shift into neutral, depress the shift
pedal repeatedly until it reaches the
end of its travel, then raise the pedal
slightly.
EC000048
CAUTION:
lDo not coast for long periods
with the engine off, and do not
tow the motorcycle a long dis-
tance. Even with gears in neu-
tral, the transmission is only
properly lubricated when the
engine is running. Inadequate
lubrication may damage the
transmission.
lAlways use the clutch when
changing gears. The engine,
transmission, and driveline are
not designed to withstand the
shock of forced shifting and
can be damaged by shifting
without using the clutch.

MOTORCYCLE CARE AND STORAGE/
CONSUMER INFORMATION
WARNING
When using the starter motor to
crank the engine, remove the spark
plug wires, and ground them to pre-
vent sparking.
4. Remove the drive chain. Thor-
oughly clean the chain with kero-
sene and lubricate it. Reinstall the
chain or store it in a plastic bag
(tied to frame for safekeeping).
5. Lubricate all control cables.
6. Block up the frame to raise both
wheels off the ground.
7. Tie a plastic bag over the exhaust
pipe outlet to prevent moisture
from entering.
8. If strong in a humid or salt-air at-
mosphere, coat all exposed metal
surfaces with a light film of oil. Do
not apply oil to any rubber parts or
the seat cover.9. Remove the battery and charge it.
Store it in a dry place and re-
change it once a month. Do not
store the battery in an excessively
warm or cold place (less than 0°C
(30°F) or more than 30°C (90°F)).
NOTE:
Make any necessary repairs before
storing the motorcycle.

After adjusting the brake pedal position,
make sure that there is no brake drag.

CHECKING THE BRAKE FLUID LEVEL
1. Stand the motorcycle on a level surface.
NOTE:
• Place the motorcycle on a suitable
stand.
• Make sure that the motorcycle is
upright.
2. Check:
• brake fluid level
Below the minimum level mark a ®
Add the recommended brake fluid to
the proper level.
Front brake
õRear brake
WARNINGWARNING
• Use only the designated brake fluid.
Other brake fluids may cause the rub-
ber seals to deteriorate, causing leak-
age and poor brake performance.
• Refill with the same type of brake fluid
that is already in the system. Mixing
brake fluids may result in a harmful
chemical reaction, leading to poor
brake performance.
• When refilling, be careful that water
does not enter the brake fluid reser-
voir. Water will significantly lower the
boiling point of the brake fluid and
could cause vapor lock.
ACHTUNG:CAUTION:
Brake fluid may damage painted sur-
faces and plastic parts. Therefore,
always clean up any spilt brake fluid
immediately.
NOTE:
In order to ensure a correct reading of the
brake fluid level, make sure that the top of
the brake fluid reservoir is horizontal.

ELECTRICAL SYSTEM
CHECKING AND CHARGING THE BATTERY
WARNINGWARNING
Batteries generate explosive hydrogen
gas and contain electrolyte which is
made of poisonous and highly caustic
sulfuric acid.
Therefore, always follow these preven-
tive measures:
• Wear protective eye gear when han-
dling or working near batteries.
• Charge batteries in a well-ventilated
area.
• Keep batteries away from fire, sparks
or open flames (e.g., welding equip-
ment, lighted cigarettes).
• DO NOT SMOKE when charging or
handling batteries.
• KEEP BATTERIES AND ELECTROLYTE
OUT OF REACH OF CHILDREN.
• Avoid bodily contact with electrolyte
as it can cause severe burns or perma-
nent eye injury.
FIRST AID IN CASE OF BODILY CON-
TACT:
EXTERNAL
• Skin – Wash with water.
• Eyes – Flush with water for 15 minutes
and get immediate medical attention.
INTERNAL
• Drink large quantities of water or milk
followed with milk of magnesia,
beaten egg or vegetable oil. Get
immediate medical attention.
ACHTUNG:CAUTION:
• This is a sealed battery. Never remove
the sealing caps because the balance
between cells will not be maintained
and battery performance will deterio-
rate.
• Charging time, charging amperage
and charging voltage for an MF bat-
tery are different from those of con-
ventional batteries. The MF battery
should be charged as explained in the
charging method illustrations. If the
battery is overcharged, the electrolyte
level will drop considerably. There-
fore, take special care when charging
the battery.
