Modifications
Modifications made to this motorcy-
cle not approved by Yamaha, or the
removal of original equipment, may
render the motorcycle unsafe for use
and may cause severe personal injury.
Modifications may also make your
motorcycle illegal to use.
Loading and accessories
Adding accessories or cargo to your
motorcycle can adversely affect sta-
bility and handling if the weight distri-
bution of the motorcycle is changed.
To avoid the possibility of an acci-
dent, use extreme caution when
adding cargo or accessories to your
motorcycle. Use extra care when
riding a motorcycle that has added
cargo or accessories. Here are some
general guidelines to follow if loading
cargo or adding accessories to your
motorcycle:
Loading
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.When loading within this weight limit,
keep the following in mind:
Cargo and accessory weight
should be kept as low and close
to the motorcycle as possible.
Make sure to distribute the
weight as evenly as possible on
both sides of the motorcycle to
minimize imbalance or instability.
Shifting weights can create a
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the
motorcycle before riding. Check
accessory mounts and cargo res-
traints frequently.
Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items,
including such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or slow
steering response.Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this motorcycle. Since Yamaha can-
not test all other accessories that may
be available, you must personally be
responsible for the proper selection,
installation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any
accessories.
Keep the following guidelines in mind,
as well as those provided under “Loa-
ding” when mounting accessories.
Never install accessories or carry
cargo that would impair the per-
formance of your motorcycle.
Carefully inspect the accessory
before using it to make sure that
it does not in any way reduce
ground clearance or cornering
clearance, limit suspension tra-
vel, steering travel or control ope-
ration, or obscure lights or reflec-
tors.
Maximum load:
195 Kg (429,98 lb)

• Accessories fitted to the hand-
lebar or the front fork area can
create instability due to impro-
per weight distribution or
aerodynamic changes. If
accessories are added to the
handlebar or front fork area,
they must be as lightweight as
possible and should be kept to
a minimum.
• Bulky or large accessories may
seriously affect the stability of
the motorcycle due to aerody-
namic effects. Wind may
attempt to lift the motorcycle,
or the motorcycle may become
unstable in cross winds. These
accessories may also cause
instability when passing or
being passed by large vehicles.
• Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the fre-
edom of movement of the ope-
rator and may limit control abi-
lity, therefore, such
accessories are not recom-
mended.Use caution when adding electri-
cal accessories. If electrical
accessories exceed the capacity
of the motorcycle’s electrical sys-
tem, an electric failure could
result, which could cause a dan-
gerous loss of lights or engine
power.
Gasoline and exhaust gas
GASOLINE IS HIGHLY FLAMMA-
BLE:
• Always turn the engine off
when refueling.
• Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.
• Never refuel while smoking or
in the vicinity of an open flame.
Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within
a short time. Always operate your
motorcycle in an area that has
adequate ventilation.
Always turn the engine off before
leaving the motorcycle unatten-
ded and remove the key from the
main switch. When parking the
motorcycle, note the following:
• The engine and exhaust sys-
tem may be hot, therefore,
park the motorcycle in a place
where pedestrians or children
are not likely to touch these hot
areas.
• Do not park the motorcycle on
a slope or soft ground, other-
wise it may fall over.
• Do not park the motorcycle
near a flammable source (e.g. a
kerosene heater, or near an
open flame), otherwise it could
catch fire.
When transporting the motorcy-
cle in another vehicle, make sure
that it is kept upright and that the
fuel cock is turned to “ON” or
“RES” (for vacuum type) / “OFF”
(for manual type). If it should lean
over, gasoline may leak out of the
carburetor or fuel tank.

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.
EWA10290
s s
WARNING
Before starting the engine,
check the function of the igni-
tion circuit cut-off system
according to the procedure
described on page 3-9.
Never ride with the sidestand
down.
1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ON” and make
sure that the engine stop switch
is set to “f”.
3. Shift the transmission into the
neutral position.
NOTE:
When the transmission is in the neu-
tral position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical
circuit.
4. Turn the starter (choke) on and
completely close the throttle.
(See page 3-7.)
5. Start the engine by pushing the
start switch.
NOTE:
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 pre-
serve the battery. Do not crank the
engine more than 10 seconds on any
one attempt.
ECA11160
CAUTION
If the oil level warning light flickers
or remains on after starting, imme-
diately stop the engine, and then
check the engine oil level and the
vehicle for oil leakage. If necessary,
add engine oil, and then check thewarning light again. If the warning
light does not go off after starting
with sufficient engine oil, have a
Yamaha dealer check the electrical
circuit.
6. After starting the engine, move
the starter (choke) back halfway.
ECA11040
CAUTION
For maximum engine life, never
accelerate hard when the engine is
cold!
7. When the engine is warm, turn
the starter (choke) off.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.

EAU16671
Shifting
1. Shifting
Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing
hills, etc.
The gear positions are shown in the
illustration.
NOTE:
To shift the transmission into the neu-
tral position, press the shift pedal
down repeatedly until it reaches the
end of its travel, and then slightly rai-
se it.
ECA10260
CAUTION
Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long
distances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
Always use the clutch while
changing gears to avoid dama-
ging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.
EAU16800
Tips for reducing fuel
consumption
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).
