Starting a cold engine NOTICE
ECA10250
See page 5-3 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 it to“”.NOTICE
ECA10240
If the oil level warning light does not
come on, have a Yamaha dealercheck the electrical circuit.
2. Close the throttle completely.3. While applying the front or rear
brake, start the engine by pushing
the start switch or by pushing the
kickstarter lever down. NOTICE:
For maximum engine life, never
accelerate hard when the en-
gine is cold!
[ECA11041]
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 possi-
ble to preserve the battery. Do not
crank the engine more than 5 sec-

EAU16793
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.
EAUM2091
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.

NOTICE
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealercheck 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 whichmight catch fire.

PERIODIC MAINTENANCE AND ADJUSTMENT
6-1

EAU17281
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 and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, depending on the
weather, terrain, geographical location,
and individual use, the maintenance in-
tervals 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 performservice.
WARNING
EWA15121
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 1-1 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 propermaintenance intervals.
