Fuel and 2-stroke engine oil
tank capsThe fuel tank cap and the 2-stroke en-
gine oil tank cap are located under the
seat. (See page 3-8.)
Fuel tank cap
To remove the fuel tank cap, turn it
counterclockwise, and then pull it off.
To install the fuel tank cap, turn it
clockwise.
2-stroke engine oil tank cap
To remove the 2-stroke engine oil tank
cap, pull it off.To install the 2-stroke engine oil tank
cap, push it into the oil tank opening.
WARNING
EWA10142
Make sure that the fuel and 2-stroke
engine oil tank caps are properly in-
stalled before riding the scooter.
Leaking fuel is a fire hazard.
EAU13213
FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
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 en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity 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. 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.

this manual, have the vehicle inspected by a Yamaha dealer.Before using this vehicle, check the following points:
ITEM CHECKS PAGE
Fuel• Check fuel level in fuel tank.
• Refuel if necessary.
• Check fuel line for leakage.3-5
2-stroke engine oil• Check oil level in oil tank.
• If necessary, add recommended oil to specified level.
• Check vehicle for oil leakage.3-7
Final transmission oil• Check vehicle for oil leakage. 6-8
Front brake• Check operation.
• If soft or spongy, have Yamaha dealer bleed hydraulic system.
• Check brake pads for wear.
• Replace if necessary.
• Check fluid level in reservoir.
• If necessary, add specified brake fluid to specified level.
• Check hydraulic system for leakage.6-14, 6-14

EAU15952
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWA10272
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.
EAUM3210
Starting a cold engineNOTICE
ECA10251
See page 5-4 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.1. Turn the key to “ ”, and when the
oil level warning light comes on,
turn the key to “ ”.NOTICE
ECA10241
If the oil level warning light does not
come on, have a Yamaha dealer
check the electrical circuit.2. Turn the starter (choke) on and
close the throttle completely. (See
page 3-7.)3. While applying the front or rear
brake, start the engine by pushing
the start switch or by pushing the
kickstarter lever down.
If the engine fails to start by push-
ing the start switch, release the
switch, wait a few seconds, and
then try again. Each starting at-
tempt should be as short as pos-
sible to preserve the battery. Do
not crank the engine more than 5
seconds on any one attempt. If the
engine does not start with the
starter motor, try using the kick-
starter.
4. After starting the engine, move the
starter (choke) lever back halfway.
5. When the engine is warm, turn the
starter (choke) off.

EAU16821
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing 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 traf-
fic lights or at railroad crossings).
EAU16831
Engine break-inThere 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 fol-
lowing 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 themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAUM2092
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3
throttle. Vary the speed of the scooter
from time to time. Do not operate it at
one set throttle position.
150–500 km (90–300 mi)
Avoid prolonged operation above 1/2
throttle.
500–1000 km (300–600 mi)
Avoid cruising speeds in excess of 3/4
throttle.1000 km (600 mi) and beyond
Avoid prolonged full throttle operation.
Vary speeds occasionally. NOTICE:
After 1000 km (600 mi) of operation,
the final transmission oil must be
changed.
[ECAM1072]
NOTICE
ECA10271
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

EAU20067
Final transmission oilThe 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 transmis-
sion 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 center-
stand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
4. Remove the final transmission oil
filler cap and its O-ring from the fi-
nal transmission case.5. Remove the final transmission oil
drain bolt and its gasket to drain
the oil from the final transmission
case.
6. Install the final transmission oil
drain bolt and its new gasket, and
then tighten the bolt to the speci-
fied torque.
7. Refill with the specified amount of
the recommended final transmis-
sion oil. WARNING! Make sure
that no foreign material entersthe final transmission case.
Make sure that no oil gets on
the tire or wheel.
[EWA11312]
8. Install the final transmission oil fill-
er cap and its new O-ring, and
then tighten the oil filler cap.
9. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
