Be a Responsible Owner
As the vehicle’s owner, you are res-
ponsible for the safe and proper ope-
ration of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are
dependent upon the use of proper
riding techniques as well as the
expertise of the operator. Every ope-
rator should know the following requi-
rements before riding this scooter.
He or she should:
●Obtain thorough instructions
from a competent source on all
aspects of scooter operation.
●Observe the warnings and main-
tenance requirements in this
Owner’s Manual.
●Obtain qualified training in safe
and proper riding techniques.
●Obtain professional technical
service as indicated in this
Owner’s Manual and/or when
made necessary by mechanical
conditions.
Safe Riding
Perform the pre-operation checks
each time you use the vehicle tomake sure it is in safe operating con-
dition. Failure to inspect or maintain
the vehicle properly increases the
possibility of an accident or equip-
ment damage. See page 4-1 for a list
of pre-operation checks.
●This scooter is designed to carry
the operator and a passenger.
TIP
Although this scooter is designed to
carry a passenger, always comply
with the local regulations.
●The failure of motorists to detect
and recognize scooters in traffic
is the predominating cause of
automobile/scooter accidents.
Many accidents have been cau-
sed by an automobile driver who
did not see the scooter. Making
yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you
are approaching and passing
through intersections, sinceintersections are the most
likely places for scooter acci-
dents to occur.
• Ride where other motorists can
see you. Avoid riding in anot-
her motorist’s blind spot.
●Many accidents involve inexpe-
rienced operators. In fact, many
operators who have been invol-
ved in accidents do not even
have a current driver’s license.
• Make sure that you are quali-
fied and that you only lend your
scooter to other qualified ope-
rators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac-
tice riding your scooter where
there is no traffic until you have
become thoroughly familiar
with the scooter and all of its
controls.
●Many accidents have been cau-
sed by error of the scooter ope-
rator. A typical error made by the
operator is veering wide on a turn
due to excessive speed or under-

Adjust the spring preload as follows.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting ring in direction (a). To
decrease the spring preload and the-
reby soften the suspension, turn the
adjusting ring in direction (b).
Align the appropriate notch in the
adjusting ring with the position indica-
tor on the shock absorber.

following information before hand-
ling the shock absorber assembly.
●Do not tamper with or attempt

●Do not subject the shock
absorber assembly to an openflame or other high heat sour-
ce. This may cause the unit to

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.

Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition sys-
tems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your scooter
require any repair, take it to a Yamaha
dealer, whose skilled technicians
have the necessary tools, experience,
and know-how to service the scooter
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
EWA15141
sWARNING
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from
water heaters or furnaces. Gasoli-
ne or gasoline vapors can ignite or
explode, causing severe injury or
property damage.
