6 Engine overheating
EW000070
WARNING
@

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.


After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
_CT-2AENOTE:@ If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.

MOTORCYCLE CARE AND STORAGE

7a. 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
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 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. _
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 degraded in one
spot.
6. Cover the muffler outlets with plas-
tic bags to prevent moisture from
entering them.
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 ex-
cessively cold or warm place (less
than 0°C or more than 30°C). For
more information on storing the
battery, see page 6-33.
NOTE:_ Make any necessary repairs before
storing the motorcycle. _
