When loading within this weight limit,
keep the following in mind:

Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Make sure
to distribute the weight as evenly
as possible on both sides of the
scooter to minimize imbalance or
instability.

Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the scooter before
riding. Check accessory mounts
and cargo restraints frequently.

Never attach any large or heavy
items to the handlebar, front fork,
or front fender. Such items can
create unstable handling or a slow
steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot test
all other accessories that may be avail-
able, you must personally be responsi-
ble for the proper selection, installationand use of non-Yamaha accessories.
Use extreme caution when selecting
and installing any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.


Never install accessories or carry
cargo that would impair the perfor-
mance of your scooter. Carefully
inspect the accessory before using
it to make sure that it does not in
any way reduce ground clearance
or cornering clearance, limit sus-
pension travel, steering travel or
control operation, or obscure lights
or reflectors.

Accessories fitted to the handle-
bar or the front fork area can
create instability due to improper
weight distribution or aerody-
namic changes. If accessories
are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.

Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodynamiceffects. Wind may attempt to lift
the scooter, or the scooter may
become unstable in cross
winds. These accessories may
also cause instability when
passing or being passed by
large vehicles.

Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the free-
dom of movement of the opera-
tor and may limit control ability,
therefore, such accessories are
not recommended.

Use caution when adding electri-
cal accessories. If electrical acces-
sories 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.

If the multi-function display indicates er-
ror code 52, this could be caused by
transponder interference. If this error
appears, try the following.
1. Use the code re-registering key to
start the engine.
NOTE:

Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the engine
from starting.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take thevehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.
If the multi-function display indicates
any error codes, note the code number,
and then have a Yamaha dealer check
the vehicle.

Sidestand
The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.
NOTE:

The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation of
the ignition circuit cut-off system.)
WARNING

EWA10240
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly as described
below and have a Yamaha dealer re-pair it if it does not function proper-
ly.
EAU15371
Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.

It prevents starting when the side-
stand is up, but neither brake is ap-
plied.

It prevents starting when either
brake is applied, but the sidestand
is still down.

It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.
WARNING

EWA10250
If a malfunction is noted, have a
Yamaha dealer check the system be-
fore riding.

EAU34172
Checking the spark plug
The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
To remove the spark plug
1. Open the rider seat. (See
page 3-14.)
2. Pull up the storage compartment
mat, and then remove the spark
plug cover by removing the
screws.3. Remove the spark plug cap.
4. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.
To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the vehicle is
ridden normally).
NOTE:

If the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to
diagnose such problems yourself. In-
stead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if

3. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove itagain to check the oil level.
NOTE:

The engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil (with or
without oil filter element replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.
