PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or
loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual
inspection, to check the following points before each ride.

Checking the spark plugThe spark plug is an important engine
component, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
it should be removed and checked in
accordance with the periodic mainte-
nance 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 scooter is ridden
normally). 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 scooter.
If the spark plug shows signs of
electrode erosion and excessive
carbon or other deposits, it should be
replaced.
Specified spark plug:
BR8HS (NGK)
or BR9HS (NGK)
Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.
Spark plug gap:
0.5 - 0.7 mmClean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
Tightening torque:
Spark plug:
20 Nm (2.0 m
•kg)
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. However, the spark
plug should be tightened to thespecified torque as soon as possible.

TiresTo maximize the performance,
durability, and safe operation of your
scooter, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.ZAUM0053
EW000082
•
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
•
The tire air pressure must be
adjusted in accordance with the
riding speed and with the total
weight of rider, passenger,
cargo, and accessoriesapproved for this model.
EW000077
Because loading has an enormous
impact on the handling, braking, per-
formance and safety characteristics of
your scooter, you should keep the
following precautions in mind.•
NEVER OVERLOAD THE SCOO-
TER! Operation of an overloaded
scooter may result in tire damage,
loss of control, or severe injury.
Make sure that the total weight of
rider, cargo, and accessories
does not exceed the specified
maximum load for the vehicle.
•
Do not carry along loosely packed
items, which can shift during a
ride.
•
Securely pack the heaviest items
close to the center of the scooter
and distribute the weight evenly
on both sides.
•
Adjust the suspension and tire air
pressure with regard to the load.
Check the tire condition and airpressure before each ride.

Cast wheelsTo maximize the performance,
durability, and safe operation of your
scooter, note the following points
regarding the specified wheels.•
The wheel rims should be
checked for cracks, bends or
warpage before each ride. If any
damage is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair
to the wheel. A deformed or
cracked wheel must be replaced.
•
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse
handling characteristics, and a
shortened tire life.
•
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be "broken in" for it
to develop its optimal
characteristics.

Adjusting the front brake
lever free playThe brake lever free play should
measure 10 - 20 mm as shown.
Periodically check the brake lever free
play and, if necessary, have a Yamaha
dealer adjust it.

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and
lubrication chart. In addition, have the
brake hose replaced every four years
or whenever it is damaged or leaking.
EAU02962
Checking and lubricating the
cablesThe operation of all control cables and
the condition of the cables should be
checked before each ride, and the
cables and cable ends should be
lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or replace
it.
Recommended lubricant:
Engine oil
EW000112
Damage to the outer sheath may
interfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafeconditions.

•
Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.
•
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
