Valve clearance
The valve clearance changes with
use, resulting in improper air-fuel mix-
ture and/or engine noise. To prevent
this from occurring, the valve clearan-
ce must be adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance and lubrication
chart.
EAU21873
Tires
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified tires.
Tire air pressure
The tire air pressure should be chec-
ked and, if necessary, adjusted befo-
re each ride.
EWA10501
Operation of this vehicle with
improper tire pressure may cause
severe injury or death from loss of
control.
The tire air pressure must be
checked and adjusted on coldtires (i.e., when the temperatu-
re of the tires equals the
ambient temperature).
The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passenger,
cargo, and accessories appro-
ved for this model.
Tire air pressure (measured on
cold tires):
0–90 kg (0–198 lb):
Front:
190 kPa (1.90 kgf/cm
2,
28 psi, 1.90 bar)
Rear:
220 kPa (2.20 kgf/cm

32 psi, 2.20 bar)
90 kg - maximum load:
Front:
210 kPa (2.10 kgf/cm

30 psi, 2.10 bar)
Rear:
250 kPa (2.50 kgf/cm
2,
36 psi, 2.50 bar)

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 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 6-25.
TIP
Make any necessary repairs before
storing the scooter.
