Do not use hard water or salt
water since it is harmful to the
engine. If water has been used
instead of coolant, replace it
with coolant as soon as possi-
ble, otherwise the cooling sys-
tem will not be protected
against frost and corrosion. If
water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.

1. Throttle cable free play
The throttle cable free play should
measure 3.0 -5.0 mm (0.12 -0.20 in) at
the throttle grip. Periodically check
the throttle cable free play and, if
necessary, adjust it as follows.
TIP
The engine idling speed must be
correctly adjusted before checking
and adjusting the throttle cable free
play.
1. Remove cowling A (See page
6-6).
2. Loosen the locknut.3. To increase the throttle cable free
play, turn the adjusting nut in
direction (a). To decrease the
throttle cable free play, turn the
adjusting nut in direction (b).

Checking and lubricating the
cables
The 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 repla-
ce it. WARNING! Damage to the
outer sheath may interfere with
proper cable operation and will
cause the inner cable to rust.
Replace a damaged cable as soon
as possible to prevent unsafe con-
ditions.

The operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-

WARNING
●Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
●After removing the radiator cap retaining bolt, 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 his-
sing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
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.

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 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]
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 degra-
ded 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 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 6-24.
TIP
Make any necessary repairs before
storing the scooter.
