MOTORCYCLE CARE AND STORAGE

stored.
Long-term
Before storing your motorcycle for several
months:
1. Follow all the instructions in the “CARE” on
page 1-29.
2. Fill up the fuel tank and add fuel stabilizer (if
available) to prevent the fuel tank from rusting
and the fuel from deteriorating.
3. Perform the following steps to protect the cyl-
inder, 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 pre-
vent damage or injury from sparking,
make sure to ground the spark plug
electrodes while turning the engine
over.
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 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 de-
graded 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 exces-
sively cold or warm place [less than 0
