from deteriorating.
3. Perform the following steps to pro- tect the cylinder, piston rings, etc.
from corrosion.
a. Remove the spark plug cap andspark 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  dam-
age 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. 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 plas- tic bag to prevent moisture from en-
tering 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 6-25.
TIP
Make any necessary repairs before stor-
ing the scooter.
