light should come on. If not, ask a
Yamaha dealer to check the elec-
trical circuit.
3. Turn the starter on and completely close the throttle. (See page 3-12.)
4. Start the engine by pushing the start switch or by pushing the kick-
starter lever down.
NOTICE
ECA17800
If the starter motor will not turn when
pushing the start switch, stop push-
ing it immediately and start the en-
gine by pushing the kickstarter lever
down in order to avoid the load onthe motor.TIPUse the kickstarter in a condition with
ambient temperature below –5 C (40F) or high altitude.
If the engine fails to start when us-
ing the start switch, release it, 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. If the engine does not
start with the starter motor, try us-
ing the kickstarter.
5. When the engine is warm, turn the starter off.
TIPThe engine is warm when it responds
quickly to the throttle with the starterturned off.NOTICE
ECA11042
For maximum engine life, never ac-
celerate hard when the engine iscold!
EAU52971
Starting a warm engine Follow the same procedure as for start-
ing a cold engine with the exception
that the starter is not required when the
engine is warm.TIP
If the engine does not start at high
altitude, start the engine with the
throttle grip opened by one degree
or two degrees.

The mark on the throttle housing

Checking the wheel bearings The front and rear wheel bearings must
be checked at the intervals specified in
the periodic maintenance and lubrica-
tion 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.
EAU52491
Battery The battery is located under the seat.
(See page 3-13.)
This model is equipped with a VRLA
(Valve Regulated Lead Acid) battery.
There is no need to check the electro-
lyte or to add distilled water. However,
the battery lead connections need to be
checked and, if necessary, tightened.
WARNING
EWA10760

Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact withskin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.
INTERNAL: Drink large quan- tities of water or milk and im-
mediately call a physician.
EYES: Flush with water for 15 minutes and seek prompt
medical attention.

Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.

KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OFCHILDREN.
To charge the battery
Have a Yamaha dealer charge the bat-
tery as soon as possi ble if it seems to
have discharged. Keep in mind that the

NOTICE
ECA16521
To charge a VRLA (Valve Regulated
Lead Acid) battery, a special (con-
stant-voltage) battery charger is re-
quired. Using a conventional batterycharger will damage the battery.
To store the battery
1. 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 main switch
is pushed to “OFF”, then dis-
connect the negative lead be-
fore disconnecting the positive
lead.
[ECA17810]

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 in- stallation. NOTICE: When install- ing the battery, be sure the main
switch is pushed to “OFF”, then
connect the positive lead before
connecting the negative
lead.
[ECA17770]

4. After installation, make sure that the battery leads are properly con-
nected to the battery terminals.
NOTICE
ECA16530
Always keep the battery charged.
Storing a discharged battery cancause permanent battery damage.
EAU52421
Replacing the fuse The main fuse is located under the
seat. (See page 3-13.)
If the fuse is blown, replace it as fol-
lows.1. Push the main switch to “OFF” 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 amperage
rating than recommended to
avoid causing extensive dam-
age to the electrical system and
possibly a fire.

9stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to pro- tect 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 spark-
ing 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 elec-
trodes while turning the en-
gine over.
[EWA10951]

4. Lubricate all control cables and the pivoting points of all levers and
pedals as well as of the sidestand/
centerstand.
5. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
6. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
7. 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 ex-
cessively cold or warm place [less
than 0  C (30 F) or more than 30
 C (90 F)]. For more information
on storing the battery, see page
6-30.
TIPMake any necessary repairs beforestoring the motorcycle.
