●Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
●Do not run engine outdoors whe-
re engine exhaust can be drawn
into a building through openings
such as windows and doors.
Loading
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution
of the scooter is changed. To avoid
the possibility of an accident, use
extreme caution when adding cargo
or accessories to your scooter. Use
extra care when riding a scooter that
has added cargo or accessories.
Here, along with the information
about accessories below, are some
general guidelines to follow if loading
cargo to your scooter:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.When loading within this weight limit,
keep the following in mind:
●Cargo and accessory weight
should be kept as low and close
to the scooter as possible. Secu-
rely pack your heaviest items as
close to the center of the vehicle
as possible and make sure to dis-
tribute the weight as evenly as
possible on both sides of the
scooter to minimize imbalance or
instability.
●Shifting weights can create a
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the scooter
before riding. Check accessory
mounts and cargo restraints fre-
quently.
• Properly adjust the suspension
for your load (suspension-
adjustable models only), and
check the condition and pres-
sure of your tires.• Never attach any large or
heavy items to the handlebar,
front fork, or front fender. Such
items can create unstable
handling or a slow steering res-
ponse.
●This vehicle is not designed to
pull a trailer or to be attached
to a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avai-
lable only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection
to Yamaha manufacture parts and
accessories or offer other modifica-
tions for Yamaha vehicles. Yamaha is
not in a position to test the products
that these aftermarket companies
produce. Therefore, Yamaha can neit-
her endorse nor recommend the use
of accessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.

If gasoline spills on your skin, wash
with soap and water. If gasoline
spills on your clothing, change your

NOTICE
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.EAU39451

not blocked, and clean it if
necessary.

WARNING
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU15362
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
●It prevents starting when the
sidestand is up, but neither brake
is applied.
●It prevents starting when either
brake is applied, but the sides-
tand is still down.
●It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
TIP
This check is most reliable if perfor-
med with a warmed-up engine.

EAU16830
Engine break-in
There 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 following 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 themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAU16951
0–150 km (0–90 mi)
●Avoid prolonged operation above
1/3 throttle.
●After every hour of operation,
stop the engine, and then let it
cool for five to ten minutes.
●Vary the engine speed from time
to time. Do not operate the engi-
ne at one set throttle position.150–500 km (90–300 mi)
●Avoid prolonged operation above
1/2 throttle.
●Rev the engine freely through the
gears, but do not use full throttle
at any time.
500–1000 km (300–600 mi)
●Avoid prolonged operation above
3/4 throttle. NOTICE: After 1000
km (600 mi) of operation, the
engine oil must be changed
and the oil strainer cleaned.
[ECA10351]
1000 km (600 mi) and beyond
●Avoid prolonged full-throttle ope-
ration. Vary the speed occasio-
nally.

NOTICE
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

trians or children are not likely
to touch them and be burned.
●Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn, increa-
sing the risk of a fuel leak and
fire.
●Do not park near grass or other
flammable materials which
might catch fire.
