(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting knob in di-
rection (b).
Compression damping force
To increase the compression dampingforce and thereby harden the compres-
sion damping, turn the adjusting knob
in direction (a). To decrease the com-
pression damping force and thereby
soften the compression damping, turn
the adjusting knob in direction (b).
NOTE:

Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary.
WARNING

EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understand
the following information before
handling the shock absorber. The
manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.

Do not tamper with or attempt to
open the gas cylinder.

Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.

Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.

Always have a Yamaha dealer
service the shock absorber. Rebound damping setting:
Minimum (soft):
20 clicks in direction (b)*
Standard:
12 clicks in direction (b)*
Maximum (hard):
3 clicks in direction (b)*

Luggage strap holders
There are four luggage strap holders
below the passenger seat, two of which
can be turned out for easier access.
EAU15300
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. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the op-
erator in fulfilling the responsibility
of raising the sidestand before start-
ing off. Therefore, check this systemregularly as described below and
have a Yamaha dealer repair it if it
does not function properly.

Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch, clutch
switch and neutral switch) has the fol-
lowing functions.

It prevents starting when the trans-
mission is in gear and the side-
stand is up, but the clutch lever is
not pulled.

It prevents starting when the trans-
mission is in gear and the clutch le-
ver is pulled, but the sidestand is
still down.

It cuts the running engine when the
transmission is in gear and the sid-
estand 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.

EAU15591
The 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 inspec-
tion, to check the following points before each ride.
NOTE:

Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very short
time; and the added safety it assures is more than worth the time involved.
WARNING

EWA11150
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating
the vehicle.

OPERATION AND IMPORTANT RIDING POINTS
EAU15950
WARNING

EWA10270

Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.

Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.

Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.
EAU16380
Starting the engine
In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:

The transmission is in the neutral
position.

The transmission is in gear with
the clutch lever pulled and the sid-
estand up.
WARNING

EWA10290

Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-19.

Never ride with the sidestand
down.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
CAUTION:

ECA11310
The oil level warning light and en-
gine trouble warning light should
come on for a few seconds, then gooff. If a warning light does not go off,
see page 3-3 for the corresponding
warning light circuit check.
2. Shift the transmission into the neu-
tral position.
NOTE:

When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a Yama-
ha dealer check the electrical circuit.
3. Start the engine by pushing the
start switch.
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 the en-
gine more than 10 seconds on any one
attempt.
CAUTION:

ECA11040
For maximum engine life, never ac-
celerate hard when the engine is

cold!
NOTE:

The engine is warm when it quickly re-
sponds to the throttle.
EAU16671
Shifting
Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc.
The gear positions are shown in the il-
lustration.
NOTE:

To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it.
CAUTION:

ECA10260

Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.

Always use the clutch while
changing gears to avoid damag-
ing the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Recommended shift points (for
Switzerland only)

acceleration are shown in the table be-
low.

NOTE:

When shifting down two gears at a
time, reduce the speed accordingly
(e.g., down to 35 km/h (22 mi/h) when
shifting from 5th to 3rd gear).
EAU16810
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Shift up swiftly, and avoid high en-
gine speeds during acceleration.

Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.

Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16841
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU17100
0–1,000 km (0–600 mi)
Avoid prolonged operation above 4,000
r/min.
1,000–1,600 km (600–1,000 mi)
Avoid prolonged operation above 6,000
r/min.
CAUTION:

ECA11150
After 1,000 km (600 mi) of operation,
the engine oil must be changed, and Shift up points:
