• 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(s) are turned to “ON” or
“RES” (for vacuum type)/”OFF”
(for manual type). If the motorcy-
cle should lean over, gasoline
may leak out of the carburetor or
fuel tank.
If you should swallow any gasoli-
ne, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immedia-
tely. If any gasoline spills on your
skin or clothing, immediately
wash the affected area with soap
and water and change your clot-
hes.

4. Coolant temperature warning lamp
The speedometer unit is equipped
with a speedometer, an odometer and
a tripmeter. The speedometer shows
riding speed. The odometer shows
the total distance traveled. The trip-
meter shows the distance traveled
since it was last set to zero with the
reset knob. The tripmeter can be used
to estimate the distance that can be
traveled with a full tank of fuel. This
information will enable you to plan
future fuel stops.
NOTE:
Only for the German model equipped
with a speed limiter:
The speed limiter prevents the vehicle
from exceeding a riding speed of 80
km/h.

WARNING
Make sure that the fuel tank cap is
properly closed and locked before
riding.
EAU13220
Fuel
Make sure that there is sufficient fuel
in the tank. When refueling, be sure to
insert the pump nozzle into the fuel
tank filler hole and to fill the tank to
the bottom of the filler tube as shown.

WARNING
Do not overfill the fuel tank,
otherwise it may overflow
when the fuel warms up and
expands.
Avoid spilling fuel on the hot
engine.
ECA10070
CAUTION
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfa-
ces or plastic parts.
EAU13320
Recommended fuel:
REGULAR UNLEADED GASOLINE
ONLY
Fuel tank capacity:
10,7 L (2,82 US gal) (2,35 Imp.gal)
Fuel reserve amount:
1,8 L (0,48 US gal) (0,40 Imp.gal)
ECA11400
CAUTION
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.
EAU13430
Catalytic converter
This model is equipped with a cataly-
tic converter in the exhaust chamber.
EWA10860
s s
WARNING
The exhaust system is hot after
operation. Make sure that the
exhaust system has cooled down
before doing any maintenance
work.

CAUTION
The following precautions must be
observed to prevent a fire hazard or
other damages.
Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.
Never park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
Do not allow the engine to idle
too long.

2-stroke engine oil
1. Oil tank cap
2. Sensor
Make sure that there is sufficient oil in
the 2-stroke engine oil tank. Add the
recommended 2-stroke engine oil if
necessary.
NOTE:
Make sure that the 2-stroke engine oil
tank cap is properly installed.
Recommended oil:
Yamalube 2 or equivalent 2-stroke
engine oil (JASO grade “FC”, or ISO
grades “EG-C” or “EG-D”)
Oil quantity:
1,3 L (1,37 US qt) (0,29 Imp.qt)
EAU13560
Fuel cock
The fuel cock supplies fuel from the
tank to the carburetor while filtering it
also.
The fuel cock has three positions:OFF
1. Arrow mark
With the lever in this position, fuel will
not flow. Always return the lever to
this position when the engine is not
running.
ON
With the lever in this position, fuel
flows to the carburetor. Normal riding
is done with the lever in this position.

this position. Fill the tank at the first
opportunity. Be sure to set the lever
back to “ON” after refueling!

richer air-fuel mixture, which is sup-
plied by the starter (choke).
Move the lever in direction (a) to turn
on the starter (choke).
Move the lever in direction (b) to turn
off the starter (choke).
