Indicator and warning lights
EAUB0001
Oil level warning light “v”
This warning light comes on when the en-
gine oil level is low.
The electrical circuit of the warning light
can be checked according to the following
procedure.
1. Turn the key to “
I” (ON). The warn-
ing light should come on for a few
seconds.
1. Oil level warning light “v”
2. Turn signal indicator light “y
y”
3. Neutral indicator light “N”
4. High beam indicator light “
1”
5. Fuel level warning light “K”
2. If the warning light does not come on,
have a Yamaha dealer check the
electrical circuit.
NOTE:
Even if the oil level is sufficient, the warn-
ing light may flicker when riding on a slope
or during sudden acceleration or decelera-
tion, but this is not a malfunction.
NOTE:
This model is equipped with a self-diagno-
sis device for the oil level warning light cir-
cuit. (See page 3-6 for an explanation of
the self-diagnosis device).
EAU00057
Turn signal indicator light “y
y”
This indicator light flashes when the turn
signal switch is pushed to the left or right.

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:
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:
EAUB0004
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.

EAU01114PRE-OPERATION CHECKS
4-1
The 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 ex-
posure 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 inspection, to check the following points before each ride.
EAU03439
Pre-operation check list
ITEM CHECK PAGE
• Check fuel level in fuel tank.
Fuel• Refuel if necessary.3-11
• Check fuel line for leakage.
• Check oil level in engine.
Engine oil• If necessary, add recommended oil to specified level. 6-6
• Check vehicle for oil leakage.
Final gear oil• Check vehicle for oil leakage.6-8
• Check operation.
• If soft or spongy, have Yamaha dealer bleed
hydraulic system.
Front brake
• Check fluid level in reservoir.3-10, 6-19
• If necessary, add recommended brake fluid to specified level.
• Check hydraulic system for leakage.
• Check operation.
• If soft or spongy, have Yamaha dealer bleed
hydraulic system.
Rear brake

b
a
4. Start the engine by pushing the start
switch.
NOTE:
If the engine fails to start, release the start
switch, wait a few seconds, and then try
again. Each starting attempt should be as
short as possible to preserve the battery.
Do not crank the engine more than 10 sec-
onds on any one attempt.
1. Starter (choke) lever
a. Starter (choke) turned on
b. Starter (choke) turned off
EC000038
The oil level warning light and fuel lev-
el warning light should come on when
the start switch is pushed, and they
should go off when the start switch is
released.
If the oil level warning light flickers or
remains on after starting, immediately
stop the engine, and then check the
engine oil level and the vehicle for oil
leakage. If necessary, add engine oil,
and then check the warning light again.
If the warning light does not come on
when pushing the start switch, or if it
does not go off after starting with suffi-
cient engine oil, have a Yamaha dealer
check the electrical circuit.
If the fuel level warning light remains
on after starting, stop the engine, and
then check the fuel level. If necessary,
refuel as soon as possible, and then
check the warning light again. If the
warning light does not come on when
pushing the start switch, or if it does
not go off after starting with sufficient
fuel, have a Yamaha dealer check the
electrical circuit.
CAUTION:5. After starting the engine, move the
starter (choke) knob/lever back
halfway.
ECA00045
For maximum engine life, never accel-
erate hard when the engine is cold!
6. When the engine is warm, turn the
starter (choke) off.
NOTE:
The engine is warm when it responds nor-
mally to the throttle with the starter (choke)
turned off.
