Checking and lubricating the
cablesThe operation of all control cables
and the condition of the cables should
be checked before each ride, and
the cables and cable ends should be
lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or re-
place it. WARNING! Damage to the
outer housing of cables may result
in internal rusting and cause in-
terference with cable movement.
Replace damaged cables as soon
as possible to prevent unsafe
conditions.
[EWA10711]
Recommended lubricant:
Yamaha Chain and Cable Lube or
engine oil
EAU22721
Changing the brake uidHave a Yamaha dealer change the
brake fl uid at the intervals specifi ed in
the TIP after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the brake master cyl-
inder and caliper as well as the brake
hose replaced at the intervals listed
below or whenever they are damaged
or leaking.● Oil seals: Replace every two
years.● Brake hose: Replace every four
years. go down. A low brake fl uid level may
indicate worn brake pads and/or brake
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fl uid level goes down suddenly, have
a Yamaha dealer check the cause be-
fore further riding.

WARNING
●
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot uid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
●
Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the
detent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the
cap while turning it counterclockwise, and then remove the cap.Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See TIP.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.

SCOOTER CARE AND STORAGE
the fuel tank from rusting and the
fuel from deteriorating.
3. 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 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 scooter 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 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 excessively 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 6-26.
TIPMake any necessary repairs before
storing the scooter.
