For your safety – pre-operation checks
EAU15599
Inspect your vehicle each time you use it to make sure the vehi cle is in safe operating condition. Always follow the inspection
and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWA11152
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage.
Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures provided inthis manual, have the vehicle inspected by a Yamaha dealer.
Before using this vehicle, check the following points:
ITEM CHECKS PAGE
Fuel Check fuel level in fuel tank.
Refuel if necessary.
Check fuel line for leakage. 3-11
Engine oil Check oil level in engine.
If necessary, add recommended oil to specified level.
Check vehicle for oil leakage. 6-12
Coolant Check coolant level in reservoir.
If necessary, add recommended coolant to specified level.
Check cooling system for leakage. 6-14
Front brake Check operation.
If soft or spongy, have Yamaha dealer bleed hydraulic system.
Check lever free play.
Adjust if necessary.
Check brake pads for wear.
Replace if necessary.

Operation and important riding points
EAU15952
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWA10272
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accidentor injury.
EAU47152
TIPThis model is equipped with:
a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the display will indicate error
code 30, but this is not a malfunc-
tion. Turn the key to “OFF” and
then to “ON” to clear the error
code. Failing to do so will prevent
the engine from starting even
though the engine will crank when
pushing the start switch.

an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. In this case,
the display will indicate error code
70, but this is not a malfunction.
Push the start switch to clear the
error code and to restart the en-gine.
EAU45128
Starting the engineIn order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.

The transmission is in gear with
the clutch lever pulled and the sid-
estand up.
See page 3-19 for more informa-
tion.
1. Turn the key to “ON” and make sure that the engine stop switch is
set to “ ”.
The following warning lights
should come on for a few seconds,
then go off.
Fuel level warning light

Coolant temperature warning
light

NOTICE
ECA11232
After changing the engine oil, make
sure to check the oil pressure as de-
scribed below.
Loosen the bleed bolt.

Start the engine and keep it
idling until oil flows out. If no oil
comes out after one minute,
turn the engine off immediately
so it will not seize. If this occurs,
have a Yamaha dealer repair the
vehicle.

After checking the oil pressure,
tighten the bleed bolt to thespecified torque.
EAU20071
CoolantThe 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.
EAU20257
To check the coolant level 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIP
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.

Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level in the cool- ant reservoir.
TIPThe coolant should be between theminimum and maximum level marks.

3. If the coolant is at or below the
minimum level mark, remove pan-
el C (See page 6-8.), remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the reservoir cap and
the panel. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the ra-
diator cap when the engine is
hot.
[EWA15162]
NOTICE: 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 cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
[ECA10473]
EAU45157
To change the coolant1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove panels A and C. (See page 6-8.)
3. Place a container under the engine to collect the used coolant.
4. Remove the radiator cap retaining bolt and radiator cap. WARNING!
Never attempt to remove the ra-
diator cap when the engine is
hot.

reservoir by turning it upside down.
8. Install the coolant reservoir by placing it in the original position, and then installing the bolts.
9. Remove the coolant drain bolt and its gasket to drain the cooling sys-
tem.
10. After the coolant is completely drained, thoroughly flush the cool-
ing system with clean tap water.
11. Install the coolant drain bolt and its new gasket, and then tighten the
bolt to the specified torque.
12. Pour the specified amount of the recommended coolant into the ra- diator and reservoir.
13. Install the coolant reservoir cap.
14. Install the radiator cap.
15. Start the engine, let it idle for sev- eral minutes, and then turn it off.
16. 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 and its retaining bolt.
17. 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.

WARNING
EWA10401

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.

After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hissingsound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIPIf coolant is not available, tap water can be temporarily us
ed 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 TIP.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
