MOTORCYCLE CARE AND STORAGE
7-4
7
Storage Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00014
CAUTION:@

Storing the motorcycle in a
poorly ventilated room or cover-
ing it with a tarp, while it is still
wet, will allow water and humid-
ity to seep in and cause rust.


To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
@
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. For motorcycles equipped with a
fuel cock that has an “OFF” posi-
tion: Turn the fuel cock lever to
“OFF”.
3. Drain the carburetor float cham-
bers by loosening the drain bolts;
this will prevent fuel deposits from
building up. Pour the drained fuel
into the fuel tank.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to pro-
tect the cylinders, piston rings, etc.
from corrosion.a. Remove the spark plug caps and
spark plugs.
b. Pour a teaspoonful of engine oil
into each spark plug bore.
c. Install the spark plug caps onto the
spark plugs, and then place the
spark plugs on the cylinder head
so that the electrodes are ground-
ed. (This will limit sparking during
the next step.)
d. Turn the engine over several times
with the starter. (This will coat the
cylinder walls with oil.)
e. Remove the spark plug caps from
the spark plugs, and then install
the spark plugs and the spark plug
caps.
EWA00003
WARNING
@ To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over. @

CAUTION:Be sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled
“ENERGY CONSERVING II”) contain anti-friction additives
which will cause clutch and/or starter clutch slippage, result-
ing in reduced component life and poor engine performance.
