Starting the engine NOTICE
ECA10250
See page 5-3 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.In order for the ignition circuit cut-off
system to enable starting, the side-
stand must be up.
See page 3-12 for more information.
1. Turn the key to “ON”.
The engine trouble warning light
should come on for a few seconds,
then go off. NOTICE: If the warn-
ing light does not go off, have a
Yamaha dealer check its electri-
cal circuit.

2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the front
or rear brake.
If the engine does not start, re-
lease the start switch, wait a few
seconds, and then try again. Each
starting attempt should be as short
as possible to preserve the bat-
tery. Do not crank the engine more
than 5 seconds on any one at-tempt. If the engine does not start
with the starter motor, try using the
kickstarter.

Braking
WARNING
EWA10300
●
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.
●
Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
●
Keep in mind that braking on a
wet road is much more difficult.
●
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.

Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
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 traffic
lights or at railroad crossings).
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 follow-
ing 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.
EAU45582
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3
throttle.
150–500 km (90–300 mi)
Avoid prolonged operation above 1/2
throttle.

Avoid prolonged operation above 3/4
throttle. NOTICE: After 1000 km (600
mi) of operation, be sure to change
the engine oil and final transmission
oil, and to clean the oil strainer.
[ECA16501]1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE

If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
EAU17213
Parking When parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10311
●
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans 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, increasing the
risk of a fuel leak and fire.
●
Do not park near grass or other
flammable materials which
might catch fire.

PERIODIC MAINTENANCE AND ADJUSTMENT
6-1

EAUS1823
Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the vehi-
cle owner/operator. The most important
points of vehicle inspection, adjust-
ment, and lubrication are explained on
the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
WARNING
EWA10321
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer perform
service.
WARNING
EWA15122
Turn off the engine when performing
maintenance unless otherwise
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 ser-
vicing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-2 for more in-
formation about carbon monox-
ide.WARNING
EWA10330
This scooter is designed for use on
paved roads only. If this scooter is
operated in abnormally dusty, mud-
dy or wet conditions, the air filter el-
ement should be cleaned or
replaced more frequently, otherwise
rapid engine wear may result. Con-
sult a Yamaha dealer for proper
maintenance intervals.
WARNING
EWA15460
Brake discs, calipers, drums, and
linings can become very hot during
use. To avoid possible burns, let
brake components cool before
touching them.

Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replacement,
or repair of the emission control devic-
es and systems may be performed by
any repair establishment or individual
that is certified (if applicable). Yamaha
dealers are trained and equipped to
perform these particular services.
