WARNING
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.
1. Before refueling, turn off the engi-
ne and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the
vicinity 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.

3. Wipe up any spilled fuel imme-
diately. NOTICE: Immediately
wipe off spilled fuel with a cle-
an, dry, soft cloth, since fuel
may deteriorate painted surfa-
ces or plastic parts.

If gasoline spills on your skin, wash
with soap and water. If gasoline
spills on your clothing, change your
clothes.

NOTICE
Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been desig-
ned to use regular unleaded gasoline
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.EAU39451

WARNING
The exhaust system is hot after
operation. To prevent a fire hazard
or burns:
●Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
●Park the motorcycle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
●Make sure that the exhaust
system has cooled down befo-
re 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.

WARNING
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand 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 control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU15362
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
●It prevents starting when the
sidestand is up, but neither brake
is applied.
●It prevents starting when either
brake is applied, but the sides-
tand is still down.
●It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
TIP
This check is most reliable if perfor-
med with a warmed-up engine.

NOTICE
See page 5-4 for engine break-in
instructions prior to operating the
vehicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the sides-
tand must be up.
See page 3-14 for more information.

WARNING
●Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
●Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
●Keep in mind that braking on a
wet road is much more difficult.
●Ride slowly down a hill, as bra-
king downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.Front

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing 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 cros-
sings).

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.
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 five to ten minutes.
●Vary the engine speed from time
to time. Do not operate the engi-
ne 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 strainer cleaned.
[ECA10351]
1000 km (600 mi) and beyond
●Avoid prolonged full-throttle ope-
ration. Vary the speed occasio-
nally.

NOTICE
If 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 pedes-
trians or children are not likely
to touch them and be burned.
●Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn, increa-
sing the risk of a fuel leak and
fire.
●Do not park near grass or other
flammable materials which
might catch fire.
