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.
_
EAU00191
NOTE:_ If knocking (or pinging) occurs, use
gasoline of a different brand or with a
higher octane grade. _
EAU02955
Fuel tank breather hose 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.

air-fuel mixture, which is supplied by
the starter (choke).
Move the lever in direction

the starter (choke).
Move the lever in direction

64. Add coolant or distilled water to
raise the coolant to the specified
level, close the coolant reservoir
cap, and then install the rider seat.
EC000080
CAUTION:_ l
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
l
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
l
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
_
EW000067
WARNING
_ Never attempt to remove the radia-
tor cap when the engine is hot. _NOTE:_ l
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
l
If the engine overheats, see
page 6-42 for further instructions.

EAU03948*
Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently if you are riding in unusually
wet or dusty areas.
1. Remove the rider seat. (See page
3-11 for rider seat removal and in-
stallation procedures.)
2. Remove cowling B from both
sides. (See page 6-5 for cowling
removal and installation proce-
dures.)
3. Remove the fuel tank bolts. Coolant reservoir capacity:
0.23 L1. Bolt (´ 2)

MOTORCYCLE CARE AND STORAGE
7-4

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 chamber
by loosening the drain bolt; 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. _
