Main switch/steering lock
The main switch/steering lock con-
trols the ignition and lighting systems,
and is used to lock the steering.
NOTE:
Be sure to use the standard key
(black bow) for regular use of the
vehicle. To minimize the risk of losing
the code re-registering key (red bow),
keep it in a safe place and only use it
for code re-registering.

Adjusting the shock
absorber assemblies
Each shock absorber assembly is
equipped with a spring preload adjus-
ting ring.

CAUTION:
Never attempt to turn an adjusting
mechanism beyond the maximum
or minimum settings.

WARNING
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability may
result.
Adjust the spring preload as follows.
1. Adjusting ring 2. Position indicator
To increase the spring preload and
thereby harden the suspension, turn
the adjusting ring on each shock
absorber assembly in direction (a). To
decrease the spring preload and the-
reby soften the suspension, turn the
adjusting ring on each shock absor-
ber assembly in direction (b).
NOTE:
Align the appropriate notch in the
adjusting ring with the position indica-
tor on the shock absorber.

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

WARNING
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand 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. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.

3. Fully charge the battery before
installation.
4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals.
ECA10630
CAUTION:
Always keep the battery char-
ged. Storing a discharged bat-
tery can cause permanent bat-
tery damage.
To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a Yamaha
dealer charge your battery.

Replacing the fuses
The main fuse and the fuse box,
which contains the fuses for the indi-
vidual circuits, are located behind
cowling B. (See page 6-6.)
If a fuse is blown, replace it as
follows.
1. Turn the key to “OFF” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.ECA10640
CAUTION:
Do not use a fuse of a higher ampe-
rage rating than recommended to
avoid causing extensive damage to
the electrical system and possibly a
fire.
3. Turn the key to “ON” and turn on
the electrical circuit in question to
check if the device operates.
4. If the fuse immediately blows
again, have a Yamaha dealer
check the electrical system.

Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition sys-
tems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your scooter
require any repair, take it to a Yamaha
dealer, whose skilled technicians
have the necessary tools, experience,
and know-how to service the scooter
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
