5. 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 damag e or injury
from sparkin g, make sure to
g roun d the spark plu g elec-
tro des while turnin g the en-
g ine over. [EWA10952]
6. Lubricate all control cables and
the pivoting points of all levers as
well as of the centerstand.
7. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle 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.
8. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
TIP
Make any necessary repairs before
storing the motorcycle.

EAU51132
For Europe only
The figures quoted are emission levels
and are not necessarily safe working
levels. Whilst there is a correlation be-
tween the emission and exposure lev-
els, this cannot be used reliably to
determine whether or not further pre-
cautions are required. Factors that in-
fluence the actual level of exposure of
work-force include the characteristics
of the work room, the other sources of
noise, etc. i.e. the number of machines
and other adjacent processes, and the
length of time for which an operator is
exposed to the noise. Also the permis-
sible exposure level can vary from
country. This information, however, will
enable the user of the machine to make
a better evaluation of the hazard and
risk.
