WARNING
_ Never attempt to remove the radia-
tor cap when the engine is hot. _NOTE:_

The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.


If the engine overheats, see
page 6-45 for further instructions.
_
EAU04280
To change the coolant
1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
2. Remove the seat. (See page 3-11
for seat removal and installation
procedures.)
3. Remove cowling D. (See page 6-7
for cowling removal and installa-
tion procedures.)
4. Remove the coolant reservoir by
removing the bolts.
5. Drain the coolant from the coolant
reservoir.
6. Remove cowlings A and C. (See
page 6-5 for cowling removal and
installation procedures.)7. Remove the fuel tank bolts, and
then lift the fuel tank. (Do not re-
move the fuel hoses.)
EW000071
WARNING
_

Make sure that the fuel tank is
well supported.


Do not tilt or pull the fuel tank
too much, otherwise the fuel
hoses may come loose, which
could cause fuel leakage.

CAUTION:_ Hard water or salt water is harmful
to the engine. You may use soft wa-
ter if you can’t get distilled water. _17. Install the radiator cap and the
coolant reservoir cap, start the en-
gine, let it idle for several minutes,
and then turn it off.
18. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap.
19. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
20. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
21. Install the right air intake duct, and
then tighten the clamp screws.22. Place the fuel tank in the original
position, and then install the bolts.
23. Install the cowlings.
24. Install the seat. Tightening torques:

CAUTION:_

Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.


To charge a sealed-type (MF)
battery, a special (constant-volt-
age) battery charger is required.
Using a conventional battery
charger will damage the battery.
If you do not have access to a
sealed-type (MF) battery charg-
er, have a Yamaha dealer charge
your battery.

cuits, are located under the seat. (See
page 3-11 for seat removal and instal-
lation procedures.)
If a fuse is blown, replace it as follows.
1. Turn the key to “OFF” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.
EC000103
CAUTION:_ Do not use a fuse of a higher amper-
age rating than recommended to
avoid causing extensive damage to
the electrical system and possibly a
fire. _

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.
_NOTE:_ 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.
