an optional anti-theft alarm by a
Yamaha dealer. Contact a Yamaha
dealer for more information.

Coolant temperature gauge With the key in the “ON” position, the
coolant temperature gauge indicates
the temperature of the coolant. The
coolant temperature varies with chang-
es in the weather and engine load. If
the needle reaches or enters the red
zone, stop the motorcycle and let the
engine cool. (See page 6-45 for further
instructions.)

4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.

NOTE:_l
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
l
Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
If the engine overheats, see page 6-45
for further instructions.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_ l
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
l
Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.
_
2. Check the coolant level in the
coolant reservoir.NOTE:_ The coolant should be between the
minimum and maximum level marks. _3. If the coolant is at or below the
minimum level mark, remove the
seat (See page 3-11 for seat re-
moval and installation proce-
dures.), and then open the coolant
reservoir cap.
4. Add coolant or distilled water to
raise the coolant to the specified
level, close the coolant reservoir
cap, and then install the 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.

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 6-45 for further instructions.

EAU03819
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 bolts and the coolant
reservoir.
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
_ l
Make sure that the fuel tank is
well supported.
l
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. _16. Install the radiator cap, start the
engine, let it idle for several min-
utes, and then turn it off.
17. 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.
18. 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.
