INSTRUMENT AND CONTROL FUNCTIONS
3-8
3Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear to-
wards “E” (Empty) as the fuel level
decreases. When the last segment
starts flashing, refuel as soon as possi-
ble. When the key is turned to “ON”, all
of the display segments of the fuel
meter will appear one after the other
and then disappear in order to test the
electrical circuit.
NOTE:This fuel meter is equipped with a self-
diagnosis system. If the electrical circuit
is defective, all the display segmentswill start flashing. If this occurs, have a
Yamaha dealer check the electrical cir-
cuit.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. When
the key is turned to “ON”, all of the dis-
play segments of the coolant tempera-
ture meter will appear one after the
other and then disappear in order to
test the electrical circuit. The coolant
temperature varies with changes in the
weather and engine load. If the top seg-
ment flashes, stop the vehicle and let
the engine cool. (See page 6-34.)
CAUTION:
ECA10020
Do not operate the engine if it isoverheated.
Transmission gear display
This display shows the selected gear.
The neutral position, however, is not
displayed, it is indicated by the neutral
indicator light.

OPERATION AND IMPORTANT RIDING POINTS

EAU16810
Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Shift up swiftly, and avoid high en-
gine speeds during acceleration.


Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.


Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16841
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU17121
0–1000 km (0–600 mi)
Avoid prolonged operation above 4500
r/min.
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 5400
r/min.
CAUTION:
ECA10331
After 1000 km (600 mi) of operation,
the engine oil and final gear oil must
be changed, and the oil filter car-tridge or element replaced.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.CAUTION:
ECA10310


Keep the engine speed out of
the tachometer red zone.


If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-cle.

6 wise the cooling 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 ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.NOTE:

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


If the engine overheats, see page6-34 for further instructions.
EAU33030
Changing the coolant
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.The coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart. Have a
Yamaha dealer change the coolant.
EAU20471
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 panel B. (See page 6-7.)
2. Remove the intake air shroud by
removing the screw and the quick
fastener screws.
3. Remove the air filter case cover by
removing the screws.1. Intake air shroud

6 Engine overheating
WARNING
EWAT1040


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.


Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the capwhile 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 coolantas 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.
