SAFETY INFORMATION
1-4

Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.
Never refuel while smoking or in
the vicinity of an open flame.
Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within a
short time. Always operate your
scooter in an area that has ade-
quate ventilation.
Always turn the engine off before
leaving the scooter unattended
and remove the key from the main
switch. When parking the scooter,
note the following:
The engine and exhaust system
may be hot, therefore, park the
scooter in a place where pedes-
trians or children are not likely to
touch these hot areas.
Do not park the scooter on a
slope or soft ground, otherwise it
may fall over.
Do not park the scooter near a
flammable source (e.g., a kero-sene heater, or near an open
flame), otherwise it could catch
fire.
If you should swallow any gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediate-
ly. If any gasoline spills on your
skin or clothing, immediately wash
the affected area with soap and
water and change your clothes.
EAU10371
Further safe-riding points
Be sure to signal clearly when
making turns.
Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.
Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.
Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.
The brake pads could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.
Always wear a helmet, gloves,
trousers (tapered around the cuff

Oil change indicator “OIL”
This indicator flashes at the initial 1000
km (600 mi), then at 5000 km (3000 mi)
and every 5000 km (3000 mi) thereafter
to indicate that the engine oil should be
changed.
After changing the engine oil, reset the
oil change indicator. (See page 6-11.)
If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval has
been reached), the indicator must bereset after the oil change for the next
periodic oil change to be indicated at
the correct time. (See page 6-11.)

when the engine is revved with the
scooter on the centerstand, but this
does not indicate a malfunction.
V-belt replacement indicator
“V-BELT”
This indicator flashes every 20000 km
(12500 mi) when the V-belt needs to be
replaced.
The electrical circuit of the indicator can
be checked according to the following
procedure.1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
2. If the indicator does not come on,

Self-diagnosis device
This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.

such an error code, note the code num-
ber, and then have a Yamaha dealer
check the vehicle.
CAUTION:

Tips for reducing fuel
consumption
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).
EAU16841
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 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
1600 km (1000 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.
EAU36530
0–1000 km (0–600 mi)
Avoid prolonged operation above
4000 r/min.
1000–1600 km (600–1000 mi)
Avoid prolonged operation above
6000 r/min.
CAUTION:
ECA11281
After 1000 km (600 mi) of operation,the engine oil must be changed, and
the oil filter cartridge or element re-
placed.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
CAUTION:
ECA10310
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

CAUTION:
ECA11620
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-
rial enters the crankcase.
9. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
10. Turn the engine off, and thencheck the oil level and correct it if
necessary.
11. Reset the oil change indicator ac-
cording to the following procedure.
To reset the oil change indicator
1. Turn the key to “ON”.
2. Hold the “OIL CHANGE” button
pushed for two to eight seconds.
3. Release the “OIL CHANGE” but-
ton, and the oil change indicator
will go off.
NOTE:
If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval has
been reached), the indicator must bereset after the oil change for the next
periodic oil change to be indicated at
the correct time. To reset the oil change
indicator before the periodic oil change
interval has been reached, follow the
above procedure, but note that the indi-
cator will come on for 1.4 seconds after
releasing the “OIL CHANGE” button,
otherwise repeat the procedure.
