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.)
EC000002
CAUTION:_ Do not operate the engine if it is
overheated. _

Anti-theft alarm (optional) This motorcycle can be equipped with
an optional anti-theft alarm by a
Yamaha dealer. Contact a Yamaha
dealer for more information.

EAU03987
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.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_

The coolant level must be checked
on a cold engine since the level
varies with engine temperature.


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:_

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.


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.


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:_

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.
