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.

WARNING
The exhaust system is hot after op-
eration. To prevent a re hazard or
burns:● Do not park the vehicle near
possible fire hazards such as
grass or other materials that

where pedestrians or children
are not likely to touch the hot
exhaust system.● Make sure that the exhaust
system has cooled down be-
fore doing any maintenance
work.● Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.

the sidestand down, or if the sid-
estand cannot be properly moved
up (or does not stay up), otherwise
the sidestand could contact the
ground and distract the operator,
resulting in a possible loss of con-
trol. Yamaha’s ignition circuit cut-
off system has been designed to
assist the operator in fulfilling the
responsibility of raising the sides-
tand before starting off. Therefore,
check this system regularly and
have a Yamaha dealer repair it if it
does not function properly.
