High beam indicator light “1”
This indicator light comes on when the
high beam of the headlight is switched on.
EAUB0002
Fuel level warning light “K”
This warning light comes on when the fuel
level drops below approximately 5.8 L.
When this occurs, refuel as soon as possi-
ble.
The electrical circuit of the warning light
can be checked according to the following
procedure.
1. Turn the key to “
I” (ON).
2. If the warning light does not come on,
have a Yamaha dealer check the
electrical circuit.
NOTE:
This model is equipped with a self-diagno-
sis device for the fuel level warning light
circuit. (See page 3-6 for an explanation of
the self-diagnosis device).

Speedometer unit
The speedometer unit is equipped with the
following:
•a speedometer (which shows riding
speed)
•a tachometer (which shows engine
r/min)
•an odometer (which shows the total
distance traveled)

•two tripmeters (which show the dis-
tance traveled since they were last
set to zero)
•a fuel reserve tripmeter (which shows
the distance traveled on the fuel re-
serve)
•an oil change indicator (which is dis-
played when the oil needs to be
changed)
•a clock.

INSTRUMENT AND CONTROL FUNCTIONS
NOTE:
Depending on the market where the
motorcycle is sold, the speedometer can
be set to either mph or km/h. When the
speedometer is set to mph, the odometer
counts in miles (1 mile = 1.61 km).Odometer and tripmeter modes
Pushing the “SET” button switches the dis-
play between the odometer mode “ODO”
and the tripmeter modes “TRIP 1” and
“TRIP 2” in the following order: ODO 6
TRIP 1 6TRIP 2 6ODO
When the fuel warning light comes on, the
display will automatically change to the fu-
el reserve tripmeter mode “TRIP F” and
start counting the distance traveled from
that point. In that case, pushing the “SET”
button switches the display between the
various tripmeter and odometer modes in
the following order: TRIP F 6TRIP 1 6
TRIP 2 6ODO 6TRIP F
To reset a tripmeter, select it by pushing
the “SET” button, and then push the “RE-
SET” button for at least one second. If you
do not reset the fuel reserve tripmeter
manually, it will reset itself automatically
and the display will return to the prior
mode after refueling and traveling several
kilometers.Oil change indicator
At the initial 1,000 km (620 mi) and every
10,000 km (6,200 mi) thereafter, the mes-
sage “OIL CHANGE” appears in the dis-
play for a few seconds when the key is
turned to “ON”, to indicate that the engine
oil should be changed.
After changing the engine oil, reset the oil
change indicator.
If the engine oil is changed before the oil
change indicator appears in the display
(i.e. before the periodic oil change interval
has been reached), the indicator must be
reset after the oil change for the next peri-
odic oil change to be indicated at the cor-
rect time.
NOTE:
When the message “OIL CHANGE”
appears in the display, be sure to change
the engine oil as soon as possible. In addi-
tion to these kilometer-based oil changes,
be sure to have a Yamaha dealer perform
the annual checks specified in the period-
ic maintenance and lubrication chart on
page 6-2.

NOTE:
The clock can only be set when the motor-
cycle is stopped. The clock does not auto-
matically adjust for Daylight Saving Time.
Therefore, when the time changes from
Standard Time to Daylight Saving Time
(and vice versa), the clock must be set
manually.
EAU00101
Tachometer
The electric tachometer allows the rider to
monitor the engine speed and keep it with-
in the ideal power range.
EC000003
Do not operate the engine in the
tachometer red zone.
Red zone: 6,400 r/min and above.
CAUTION:

Self-diagnosis device
NOTE:
When the key is turned to “
I” (ON), the
tachometer and speedometer needles
should move to the maximum, then back
to zero. In addition, the oil level warning
light and fuel level warning light should
come on for a few seconds, then go off. If
the tachometer or speedometer needle
does not move as described or either of
the warning lights does not come on, have
a Yamaha dealer check the electrical cir-
cuits.
This model is equipped with a self-diagno-
sis device for the following electrical cir-
cuits:
•speedometer
•tachometer
•oil level warning light
•throttle position sensor
•speed sensor.

OPERATION AND IMPORTANT RIDING POINTS
EAU00424
Tips for reducing fuel
consumption
Fuel consumption depends largely on your
riding style. Consider the following tips to
reduce fuel consumption:
•Thoroughly warm up the engine.
•Turn the starter (choke) off as soon
as possible.
•Shift up swiftly, and avoid high engine
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 letting it
idle for an extended length of time
(e.g., in traffic jams, at traffic lights or
at railroad crossings).

Engine break-in
There is never a more important period in
the life of your engine than the period be-
tween 0 and 1,600 km (1,000 mi). For this
reason, you should read the following ma-
terial carefully.
Since the engine is brand new, do not put
an excessive load on it for the first 1,600
km (1,000 mi). The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During this
period, prolonged full-throttle operation or
any condition that might result in engine
overheating must be avoided.
EAU01171
0-1,000 km (0-600 mi)
Avoid prolonged operation above 1/3 throt-
tle.
1,000-1,600 km (600-1,000 mi)
Avoid prolonged operation above 1/2 throt-
tle.
EC000056
After 1,000 km (600 mi) of operation,
the engine oil and final gear oil must be
changed, and the oil filter cartridge/ele-
ment replaced.
1,600 km (1,000 mi) and beyond
The vehicle can now be operated normal-
ly.
EC000049
If any engine trouble should occur dur-
ing the engine break-in period, immedi-
ately have a Yamaha dealer check the
vehicle.

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

NOTE:
Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in a
false reading.
2. Start the engine, warm it up for sever-
al minutes, and then turn it off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located at
the bottom-left side of the crankcase.
NOTE:
The engine oil should be between the min-
imum and maximum level marks.
4. If the engine oil is below the minimum
level mark, add sufficient oil of the
recommended type to raise it to the
correct level.To change the engine oil without oil
filter element replacement
1. Start the engine, warm it up for sever-
al minutes, and then turn it off.
2. Place an oil pan under the engine to
collect the used oil.
3. Remove the engine oil filler cap and
drain bolt to drain the oil from the
crankcase.

result in a false reading.2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:
The oil level should be at the brim of the
filler hole.
3. If the oil is below the brim of the filler
hole, add sufficient oil of the recom-
mended type to raise it to the correct
level.

Final gear oil
The final gear case must be checked for oil
leakage before each ride. If any leakage is
found, have a Yamaha dealer check and
repair the motorcycle. In addition, the final
gear oil level must be checked and the oil
changed as follows at the intervals speci-
fied in the periodic maintenance and lubri-
cation chart.
