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.
