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.
EAU13270
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.
EAU13432
Catalytic converter
This model is equipped with a cataly-
tic converter in the exhaust system.
EWA10861
sWARNING
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.
ECA10701
NOTICE
Use only unleaded gasoline. The
use of leaded gasoline will cause
unrepairable damage to the cataly-
tic converter.
Recommended fuel:
REGULAR UNLEADED

EAU15595
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the ins-
pection and maintenance procedures and schedules described in the Owner’s Manual.
EWA11151
sWARNING
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment dama-
ge. Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures pro-
vided in this manual, have the vehicle inspected by a Yamaha dealer.
Before using this vehicle, check the following points:
FOR YOUR SAFETY – PRE-OPERATION CHECKS
4-1

EAU17281
Periodic inspection, adjustment, and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. Safety is an obligation
of the vehicle owner/operator. The
most important points of vehicle ins-
pection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, depending on
the weather, terrain, geographical
location, and individual use, the main-
tenance intervals may need to be
shortened.
EWA10321
sWARNING
Failure to properly maintain the
vehicle or performing maintenance
activities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle
service, have a Yamaha dealer per-
form service.
EWA15121
sWARNING
Turn off the engine when perfor-
ming maintenance unless otherwi-
se specified.
●A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.
●Running the engine while servi-
cing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-1 for more
information about carbon
monoxide.
EWA10330
sWARNING
This scooter is designed for use on
paved roads only. If this scooter is
operated in abnormally dusty,
muddy or wet conditions, the air fil-
ter element should be cleaned or
replaced more frequently, otherwi-
se rapid engine wear may result.
Consult a Yamaha dealer for proper
maintenance intervals.

Periodic maintenance and lubrication chart
TIP
●The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK,
a mileage-based maintenance, is performed instead.
●From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.

EAU19622
Checking the spark plug
The spark plug is an important engine
component, which should be chec-
ked periodically, preferably by a
Yamaha dealer. Since heat and depo-
sits will cause any spark plug to
slowly erode, it should be removed
and checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of the spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally). If the spark plug shows a
distinctly different color, the engine
could be operating improperly. Do not
attempt to diagnose such problems
yourself. Instead, have a Yamaha
dealer check the vehicle.
If the spark plug shows signs of elec-
trode erosion and excessive carbon
or other deposits, it should be repla-
ced.Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
1. Spark plug gap
Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
Spark plug gap:
0.6–0.7 mm (0.024–0.028 in)

TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4–1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
EAU20064
Final transmission oil
The final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
Yamaha dealer check and repair the
scooter. In addition, the final trans-
mission oil must be changed as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm up the
final transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the centers-
tand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
4. Remove the final transmission oil
filler cap and final transmission
drain bolt to drain the oil from the
final transmission case.
1. Final transmission oil filler cap
5. Install the final transmission oil
drain bolt, and then tighten it to
the specified torque.
