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.
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of
control, which could cause an acci-
dent or injury.
EAU16053
Starting a cold engine
In 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
sidestand up.
See page 3-13 for more information.
1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ ” and make
sure that the engine stop switch
is set to “ ”.
3. Shift the transmission into the
neutral position. (See page 5-2.)
The neutral indicator light should
come on. If not, ask a Yamaha
dealer to check the electrical cir-
cuit.
4. Turn the starter (choke) on and
completely close the throttle.
(See page 3-11).
5. Start the engine by pushing the
start switch.
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 seconds on
any one attempt.
6. After starting the engine, move
the starter (choke) back halfway.
NOTICE:For maximum engine
life, never accelerate hard
when the engine is cold!
[ECA11041]
7. When the engine is warm, turn
the starter (choke) off.
TIP
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.

Tips for reducing fuel con-
sumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
●Turn the starter (choke) off as
soon as possible.
●Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
●Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
●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 cros-
sings).
EAU16830
Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1000 km
(600 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAUS1560
0–500 km (0–300 mi)
●Avoid prolonged operation above
4000 r/min.
●After every hour of operation,
stop the engine, and then let it
cool for five to ten minutes.
●Vary the engine speed from time
to time. Do not operate the engi-
ne at one set throttle position.500–1000 km (300–600 mi)
●Avoid prolonged operation above
6000 r/min.
●Rev the engine freely through the
gears, but do not use full throttle
at any time. NOTICE:After 1000
km (600 mi) of operation, the
transmission oil must be chan-
ged.
[ECA10370]
1000 km (600 mi) and beyond
●The vehicle can now be operated
normally.
ECA10310
●Keep the engine speed out of
the tachometer red zone.
●If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.

TIP
●The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK,
a mileage-based maintenance, is performed instead.
●From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.

Checking the spark plug
The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause
any spark plug to slowly erode, the
spark plug should be removed and
checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug
1. Remove panel A. (See page 6-8).
2. Remove the spark plug cap.
1. Spark plug cap
3. Remove the spark plug as
shown, using the spark plug
wrench, which is located in the
storage compartment. (See page
6-1).
1. Spark plug wrench
To check the spark plug
1. Check that the porcelain insula-
tor around the center electrode of
the spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).
TIP
If the spark plug shows a distinctly
different color, the engine could be
operating improperly. Do not attempt
to diagnose such problems yourself.

TIP
Make sure that the vehicle is positio-
ned straight up when checking the oil
level. A slight tilt to the side can result
in a false reading.
3. Remove the oil check bolt, and
then check the oil level.
TIP
The oil should be at the brim of the
check hole.
4. If the oil is below the brim of the
check hole, remove the oil filler
cap, add sufficient oil of the
recommended type to raise it to
the correct level, and then install
the oil filler cap.
5. Install the oil check bolt, and then
tighten it to the specified torque.To change the transmission oil
1. Oil check bolt
2. Transmission oil drain bolt
3. Washer
1. Place an oil pan under the trans-
mission oil case to collect the
used oil.
2. Remove the drain bolt and the oil
check bolt to drain the oil.
3. Install the drain bolt and the
check bolt, and then tighten them
to the specified torques.4. Remove the oil filler cap, refill
with the specified amount of the
recommended transmission oil,
and then install and tighten the oil
filler cap. NOTICE: Make sure
that no foreign material enters
the transmission case.
[ECAM1021]
5. Start the engine and let it idle for
several minutes while checking
the transmission oil case for oil
leakage. If oil is leaking, imme-
diately turn the engine off and
check for the cause.

Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU39086
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
●The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
●Make sure that the vehicle 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.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove
panel A. (See page 6-8).
4. Remove the coolant reservoir
cap, add coolant to the maxi-
mum level mark, and then install
the reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to
remove the radiator cap when
the engine is hot.
[EWA15161]. NOTI-
CE: 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 coo-
lant, replace it with coolant as
soon as possible, otherwise
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.

11. Pour the recommended coolant
into the radiator until it is full.
12. Install the radiator cap.
13. Run the engine several minutes.
Stop the engine and recheck the
coolant level in the radiator. If it is
low, add more coolant until it rea-
ches the top of the radiator.
14. Install the radiator cap, radiator
cap retainer and radiator cap
retaining bolt.
15. Fill the coolant reservoir with
coolant up to the maximum level.
16. Install the coolant reservoir cap
and check for coolant leakage.TIP
If any leakage is found, ask a Yamaha
dealer to inspect the cooling system.
17. Install the cowling and the panel.
