occurs, have a Yamaha dealer check
the self-diagnosis system.
The electrical circuit of the warning
light can be checked by turning the
key to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come
on initially when the key is turned to

Odometer, tripmeter and oil change
tripmeter modes
Pushing the “SELECT” button switch-
es the display among the odom-
eter mode “ODO”, the tripmeter mode
“TRIP” and the oil change tripmeter
“OIL CHANGE TRIP” in the following
order:
ODO → TRIP → OIL CHANGE TRIP
→ ODO
OdometerTIPIf the odometer indicates “-----”, have
a Yamaha dealer check the multi-
function display, as it may be faulty.
Tripmeter
To reset the tripmeter, select it by
pushing the “SELECT” button until
“TRIP” is displayed, and then push the
“RESET” button at least 1 second.TIPIf the tripmeter indicates “-----”, have
a Yamaha dealer check the multi-
function display, as it may be faulty.
Oil change tripmeter
To reset the oil change tripmeter, se-
lect it by pushing the “SELECT” but-
ton until “OIL CHANGE TRIP” is dis-
played, and then push the “RESET”
button at least 3 seconds.
Push the “SELECT” button again to
start the oil change tripmeter; the dis-
play changes to the ODO mode.
Oil change indicator “7”
This indicator flashes at the initial
1000 km (600 mi), then at every 3000
km (1800 mi) thereafter to indicate
that the engine oil should be changed.
After changing the engine oil, reset
the oil change tripmeter.
If the engine oil is changed before
the oil change indicator flashes (i.e.
before the periodic oil change interval
has been reached), the oil change
tripmeter must be reset after the
oil change for the next periodic oil
change to be indicated at the correct
time.TIP●
If the oil change tripmeter is reset
before the initial 1000 km (600
mi), the next periodic oil change

WARNING
Gasoline and gasoline vapors are
extremely ammable. To avoid res
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.
1. Before refueling, turn off the en-
gine and be sure that no one is
sitting on the vehicle. Never re-
fuel while smoking, or while in the

vicinity of sparks, open fl ames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfi ll the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank fi ll-
er hole. Stop fi lling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine
or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel im-
mediately.
NOTICE:
Immedi-
ately wipe off spilled fuel with a
clean, dry, soft cloth, since fuel
may deteriorate painted sur-
faces or plastic parts.[ECA10071]
4. Be sure to securely close the fuel
tank cap.
EWA15151
WARNING
Gasoline is poisonous and can
cause injury or death. Handle
gasoline with care. Never siphon
gasoline by mouth. If you should
swallow some gasoline or inhale a
lot of gasoline vapor, or get some
gasoline in your eyes, see your
doctor immediately. If gasoline
spills on your skin, wash with soap
and water. If gasoline spills on your
clothing, change your clothes.

Recommended fuel:
REGULAR UNLEADED GASO-
LINE ONLY
Fuel tank capacity:
7.4 L (1.96 US gal) (1.63 Imp.gal)
ECA11400
NOTICEUse only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use of unleaded fuel will extend spark plug
life and reduce maintenance costs.

OPERATION AND IMPORTANT RIDING POINTS
EAU16820
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:● Avoid high engine speeds during
acceleration.● 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 cross-
ings).
EAU16830
Engine break-inThere is never a more important pe-
riod 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 fi rst
1000 km (600 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating
must be avoided.
EAU16951
0 ~ 150 km (0 ~ 90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for fi ve to
ten minutes.
Vary the engine speed from time to
time. Do not operate the engine at
one set throttle position.
150 ~ 500 km (90 ~ 300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the
gears, but do not use full throttle at
any time.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above
3/4 throttle.
NOTICE:
After 1000 km
(600 mi) of operation, the engine oil
must be changed and the oil strain-
er cleaned.
[ECA10351]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

WARNING
● Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.● Do not park on a slope or on
soft ground, otherwise the ve-
hicle may overturn, increasing
the risk of a fuel leak and re.● Do not park near grass or other
flammable materials which
might catch re.
