Fuel tank cap
To open the fuel tank cap
Open the fuel tank cap lock cover, in-
sert the key into the lock, and then turn
it 1/4 turn clockwise. The lock will be
released and the fuel tank cap can be
opened.
To close the fuel tank cap
1. Push the fuel tank cap into posi- tion with the key inserted in the
lock.
2. Turn the key counterclockwise to the original position, remove it,
and then close the lock cover.
TIP
The fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly closed and locked.
WARNING
EWA11092
Make sure that the fuel tank cap is
properly close d after fillin g fuel.
Leakin g fuel is a fire hazar d.
EAU13222
Fuel
Make sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline an d gasoline vapors are
extremely flammab le. To avoid fires
an d explosions an d to re duce the
risk of injury when refueling , follow
these instructions.
1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling 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.1. Unlock.

ately. NOTICE: Immediately
wipe off spille d fuel with a clean,

4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous an d can cau-
se injury or death. Han dle gasoline
with care. Never siphon gasoline by
mouth. If you shoul d swallow some
g asoline or inhale a lot of g asoline
vapor, or get some g asoline in your
eyes, see your doctor imme diately. If
g asoline spills on your skin, wash
with soap an d water. If gasoline
spills on your clothin g, chan ge your
clothes.
EAU75320
NOTICE
ECA11401
Use only unlea ded g asoline. The use
of lead ed g asoline will cause severe
d ama ge to internal en gine parts,
such as the valves an d piston rin gs,
as well as to the exhaust system.
TIP
 This mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).
 Check that gasoline nozzle has
the same identifier when fueling.
Your Yamaha engine has been de-
signed to use premium unleaded gas-
oline with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
Recommen ded fuel:
Premium unleaded gasoline (Gaso-
hol [E10] acceptable)
Fuel tank capacity: 17 L (4.5 US gal, 3.7 Imp.gal)
Fuel reserve amount (when the fuel
level warnin g lig ht comes on):
3.4 L (0.90 US gal, 0.75 Imp.gal)

Fuel tank overflow hose
Before operating the vehicle:
 Check the fuel tank overflow hose
connection.
 Check the fuel tank overflow hose
for cracks or damage, and replace
it if necessary.
 Make sure that the end of the fuel
tank overflow hose is not blocked,
and clean it if necessary.
 Make sure that the end of the fuel
tank overflow hose is positioned
as shown.
TIP
See page 7-12 for canister information.
EAU13447
Catalytic converters
This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazar d or
b urns:
 Do not park the vehicle near
possi ble fire hazar ds such as
g rass or other materials that
easily burn.
 Park the vehicle in a place
where ped estrians or child ren
are not likely to touch the hot
exhaust system.
 Make sure that the exhaust sys-
tem has coole d down before
d oin g any maintenance work.
 Do not allow the eng ine to idle
more than a few minutes. Lon g
i d lin g can cause a b uild-up of
heat.
NOTICE
ECA10702
Use only unlea ded g asoline. The use
of lead ed g asoline will cause unre-
paira ble damag e to the catalytic
converter.

In order for the ignition circuit cut-off
system (page 4-31) 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.
To start the engine
1. Turn the key to “ON” and make sure that the engine stop switch is
set to “ ”.
2. Confirm that the following lights perform a circuit check (come on
for a few seconds and then go off). Engine trouble warning light
 ABS warning light*
 Oil level warning light
 Fuel level warning light*
 Coolant temperature warning
light
 Traction control system indi-
cator light
 Shift timing indicator light
 Immobilizer system indicator
light
TIP

come on and stay on until the ve-
hicle reaches a traveling speed of
10 km/h (6 mi/h).
 The fuel level warning light will
stay on if you are low on fuel.
NOTICE

Tips for re ducin g fuel con-
sumption
Fuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
 Shift up swiftly, and avoid high en-
gine speeds during acceleration.
 Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the en-
gine.
 Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16842
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAU17085
0–1000 km (0–600 mi)
Avoid prolonged operation above 8300
r/min. NOTICE: After 1000 km (600
mi) of operation, the en gine oil must
b e chan ged an d the oil filter car-
tri dge or element replace d.
[ECA10303]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 9900
r/min.

The vehicle can now be operated nor-
mally.
NOTICE
ECA10311
 Keep the en gine spee d out of
the tachometer red zone.
 If any en gine trou ble shoul d oc-
cur durin g the en gine break-in
perio d, imme diately have a
Yamaha dealer check the vehi-
cle.

discoloration of the exhaust pipe, but
this is normal.

Parkin g
When parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10312
Since the en gine an d exhaust
system can become very hot,
park in a place where ped estri-
ans or chil dren are not likely to
touch them and b e burne d.
 Do not park on a slope or on soft
groun d, otherwise the vehicle
may overturn, increasin g the
risk of a fuel leak an d fire.
 Do not park near grass or other
flammab le materials which
mi ght catch fire.
