CAUTION:@ l
Immediately wipe off spilled fuel
with a clean, dry, soft cloth,
since fuel may deteriorate paint-
ed surfaces or plastic parts.
l
For Germany only: Whenever
replacement is necessary, use a
fuel tank cap of the same spe-
cial design as the original.

NOTE:@ If knocking (or pinging) occurs, use
gasoline of a different brand or with a
higher octane grade. @

Fuel tank breather hose
(for Germany only) Before operating the motorcycle:l
Check the fuel tank breather hose
connection.
l
Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.
l
Make sure that the end of the fuel
tank breather hose is not blocked
and clean it if necessary.

Starter (choke) lever Starting a cold engine requires a richer
air-fuel mixture, which is supplied by
the starter (choke).
Move the lever in direction
a to turn on
the starter (choke).
Move the lever in direction
b to turn off
the starter (choke). Recommended fuel:
Regular unleaded gasoline with a
research octane number of 91 or
higher

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:@ l
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.
l
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. @
