Use caution when adding electri-
cal accessories. If electrical
accessories exceed the capacity
of the scooter’s electrical system
an electric failure could result,
which could cause a dangerous
loss of lights or engine power.
Gasoline and exhaust gas
GASOLINE IS HIGHLY FLAMMA-
BLE:
• Always turn the engine off
when refueling.
• 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 sys-
tem may be hot, therefore,
park the scooter in a place
where pedestrians 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 gasoli-
ne, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immedia-
tely. If any gasoline spills on your
skin or clothing, immediately
wash the affected area with soap
and water and change your clot-
hes.
EAU10360
Further safe-riding points
Be sure to signal clearly when
making turns.
Braking can be extremely difficult
on a wet road. Avoid hard bra-
king, because the scooter could
slide. Apply the brakes slowly
when stopping on a wet surface.
Slow down as you approach a
corner or turn. Once you have
completed 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 cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Slow down and
cross them with caution. Keep
the scooter upright, otherwise it
could slide out from under you.
The brake lining could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

Checking the spark plug
1. Spark plug cap
The spark plug is an important engine
component, which should be chec-
ked periodically, preferably by a
Yamaha dealer. Since heat and depo-
sits will cause any spark plug to
slowly erode, it should be removed
and checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of the spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is riddennormally). If the spark plug shows a
distinctly different color, the engine
could be defective. Do not attempt to
diagnose such problems yourself.
Instead, have a Yamaha dealer check
the vehicle.
If the spark plug shows signs of elec-
trode erosion and excessive carbon
or other deposits, it should be repla-
ced.
1. Spark plug wrench
Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
1. Spark plug gap
NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4~1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
Tightening torque:
Spark plug:
20 Nm 2,0 m•kgf, 14,46ft•lb)
Spark plug gap:
0,7~0,8 mm (0,0275in-0,0315in)
