Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do
not understand, ask your Yamaha
dealer.
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of
control, which could cause an acci-
dent or injury.
EAU16055
Starting a cold engine
In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
See page 3-14 for more information. 1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ ” and make sure that the engine stop switch
is set to “ ”.
3. Shift the transmission into the neutral position. The neutral indi-
cator light should come on. If not,
ask a Yamaha dealer to check the
electrical circuit.
4. Turn the starter (choke) on and completely close the throttle.
(See page 3-12).
5. Start the engine by pushing the start switch.
If the engine fails to start, release
the start switch, wait a few
seconds, and then try again.
Each starting attempt should be as short as possible to preserve
the battery. Do not crank the
engine more than 10 seconds on
any one attempt.
6. After starting the engine, move the starter (choke) back halfway.
7. When the engine is warm, turn the starter (choke) off.
TIP
The engine is warm when it responds
quickly to the throttle with the starter
(choke) turned off.
ECA11042
For maximum engine life, never
accelerate hard when the engine is
cold!

Checking the wheel bearings
The front and rear wheel bearings
must be checked at the intervals spe-
cified in the periodic maintenance and
lubrication chart. If there is play in the
wheel hub or if the wheel does not
turn smoothly, have a Yamaha dealer
check the wheel bearings.

Battery
1. Battery
This model is equipped with a VRLA
(Valve Regulated Lead Acid) battery.
There is no need to check the elec-
trolyte or to add distilled water. Howe-
ver, the battery lead connections
need to be checked and, if necessary,
tightened.
EWA10760
Electrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyeswhen working near batteries.
In case of contact, administer
the following FIRST AID.
• EXTERNAL: Flush with plenty of water.
• INTERNAL: Drink large quan- tities of water or milk and
immediately call a physician.
• EYES: Flush with water for 15 minutes and seek prompt
medical attention.
Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and provi-
de sufficient ventilation when
charging it in an enclosed space.
KEEP THIS AND ALL BATTE-
RIES OUT OF THE REACH OF
CHILDREN.
To charge the battery
Have a Yamaha dealer charge the
battery as soon as possible if it seems
to have discharged. Keep in mind that
the battery tends to discharge more
quickly if the vehicle is equipped with
optional electrical accessories.WARNING

To charge a VRLA (Valve Regulated
Lead Acid) battery, a special (cons-
tant-voltage) battery charger is
required. Using a conventional bat-
tery charger will damage the bat-
tery.
To store the battery1. If the vehicle will not be used for more than one month, remove
the battery, fully charge it, and
then place it in a cool, dry place.
NOTICE: When removing the
battery, be sure the key is tur-
ned to “ ” then disconnect
the negative lead before dis-
connecting the positive lead.
[ECA16302]
2. If the battery will be stored for more than two months, check it
at least once a month and fully
charge it if necessary.
3. Fully charge the battery before installation. NOTICE: When ins-
talling the battery, be sure the
key is turned to “ ”, then connect the positive lead befo-
re connecting the negative
lead.
[ECA16840]
4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals.
1. Negative battery lead (black)
2. Positive battery lead (red)
ECA16530
Always keep the battery charged.
Storing a discharged battery can
cause permanent battery damage.
EAU23482
Replacing the fuse
1. Main fuse
2. Spare main fuse
The fuse holder is located under the
seat. (See page 3-12).
If the fuse is blown, replace it as
follows.1. Turn the key to “ ” and turn off all electrical circuits.
2. Remove the blown fuse, and then install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher ampera-
ge rating than recommended
to avoid causing extensive
damage to the electrical sys-
tem and possibly a fire.

2. Turn the fuel cock lever to “OFF”.
3. Drain the carburetor float cham-ber by loosening the drain bolt;
this will prevent fuel deposits
from building up. Pour the drai-
ned fuel into the fuel tank.
4. Fill up the fuel tank and add fuel stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to protect the cylinder, piston rings,
etc. from corrosion.a. Remove the spark plug cap and spark plug.
b. Pour a teaspoonful of engine oil into the spark plug bore.
c. Install the spark plug cap onto the spark plug, and then
place the spark plug on the
cylinder head so that the
electrodes are grounded.
(This will limit sparking during
the next step.)
d. Turn the engine over several times with the starter. (This
will coat the cylinder wall with
oil.) e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the
spark plug cap. WARNING!
To prevent damage or injury
from sparking, make sure
to ground the spark plug
electrodes while turning the
engine over.
[EWA10951]
6. Lubricate all control cables andthe pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
7. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alter-
natively, turn the wheels a little
every month in order to prevent
the tires from becoming degra-
ded in one spot.
8. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
9. Remove the battery and fully charge it. Store it in a cool, dry
place and charge it once a
month. Do not store the battery in
an excessively cold or warm pla- ce [less than 0 °C (30 °F) or more
than 30 °C (90 °F)]. For more
information on storing the bat-
tery, see page 6-32.
TIP
Make any necessary repairs before
storing the motorcycle.
