Adjusting the shock
absorber assemblies
1. Spring preload adjusting ring
2. Position indicator
Each shock absorber assembly is
equipped with a spring preload adjus-
ting ring.

CAUTION:
Never attempt to turn an adjusting
mechanism beyond the maximum

WARNING
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability may
result.
Adjust the spring preload as follows.
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.

Sidestand
1. Sidestand switch
2. Sidestand
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.
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
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.
EAU15361
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the
sidestand is up, but neither brake
is applied.
It prevents starting when either
brake is applied, but the sides-
tand 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.
EWA10260

WARNING
The vehicle must be placed on
the centerstand during this ins-
pection.
If a malfunction is noted, have
a Yamaha dealer check the
system before riding.

The condition of a vehicle is the
owner’s responsibility. Vital compo-
nents 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 follo-
wing points before each ride.
NOTE:
Pre-operation checks should be
made each time the vehicle is used.
Such an inspection can be accom-
plished in a very short time; and the
added safety it assures is more than
worth the time involved.

WARNING
If any item in the Pre-operation
check list is not working properly,
have it inspected and repaired
before operating the vehicle.

WARNING
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thoroughly
understand.
Never start the engine or ope-
rate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of cons-
ciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
For safety, always start the
engine with the centerstand
down.

Starting a cold engine
ECA10250
CAUTION:
See page 5-3 for engine break-in
instructions prior to operating the
vehicle for the first time.
1. Turn the key to “f”.
2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the
front or rear brake.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank theengine more than 10 seconds on any
one attempt.
ECA11040
CAUTION:
For maximum engine life, never
accelerate hard when the engine is
cold!

WARNING
Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the follo-
wing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING

GRAPHICAL LOCATION, AND INDIVI-
DUAL USE, THE MAINTENANCE
INTERVALS MAY NEED TO BE
SHORTENED.
