Tires
Tires are the only contact between the
vehicle and the ground. Safety in all
conditions of riding depends on a rela-
tively small area of contact. Therefore,
it is essential to maintain the tires in
good condition at all times and replace
them at the appropriate time with the
specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING
EWA15371
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or d eath from loss of
control.
The tire air pressure must be
checked and a djuste d on col d tires
(i.e., when the temperature of the
tires equals the am bient tempera-
ture).

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 turning 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.
