lyte or to add distilled water. However,
the battery lead connections need to be
checked and, if necessary, tightened.

NOTICE
ECA16522
To charge a VRLA (Valve Regulated
Lead Acid) battery, a special (con-
stant-voltage) battery charger is re-
quired. Using a conventional batterycharger will damage the battery.
To store the battery
1. If the vehicle will not be used for more than one month, remove the
battery, fully charge it, and then
place it in a cool, dry place.
NOTICE: When removing the
battery, be sure to turn the main
switch off, then disconnect the
negative lead before discon-
necting the positive lead.
[ECA16304]
2. If the battery will be stored for more than two months, check it at least
once a month and fully charge it if
necessary.
3. Fully charge the battery before in- stallation. NOTICE: When install-
ing the battery, be sure to turn the main switch off, then con-
nect the positive lead before
connecting the negative
lead.

nance.
2. Follow all instructions in the Care section of this chapter.
3. Fill up the fuel tank, adding fuel stabilizer according to product in-
structions. Run the engine for 5
minutes to distribute treated fuel
through the fuel system.
4. For vehicles equipped with a fuel cock: Turn the fuel cock lever to
the off position.
5. For vehicles with a carburetor: To prevent fuel deposits from building
up, drain the fuel in the carburetor
float chamber into a clean contain-
er. Retighten the drain bolt and
pour the fuel back into the fuel
tank.
6. Use a quality engine fogging oil ac- cording to product instructions to
protect internal engine compo-
nents from corrosion. If engine fog-
ging oil is not available, perform
the following steps for each cylin-
der:
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.)
WARNING! To prevent dam-
age or injury from sparking,
make sure to ground the
spark plug electrodes while
turning the engine
over.
[EWA10952]
e. Remove the spark plug capfrom the spark plug, and then
install the spark plug and the
spark plug cap.
7. Lubricate all control cables, pivots, levers and pedals, as well as the
sidestand and centerstand (if
equipped).
8. Check and correct the tire air pres- sure, and then lift the vehicle so
that all wheels are off the ground.
Otherwise, turn the wheels a little
once a month in order to prevent the tires from becoming degraded
in one spot.
9. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
10. Remove the battery and fully charge it, or attach a maintenance
charger to keep the battery opti-
mally charged. NOTICE: Confirm
that the battery and its charger
are compatible. Do not charge a
VRLA battery with a convention-
al charger.
[ECA26330]
TIP
If the battery will be removed,
charge it once a month and store it
in a temperate location between
0-30 C (32-90 F).
