Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing ring, a rebound damping force ad-
justing dial and a compression
damping force adjusting screw.
NOTICE

ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Spring preload
Spring preload adjustment should be
made by a Yamaha dealer, since this
service requires special tools and tech-
nical skills. The specified settings are
listed below.
The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter the dis-
tance A is, the higher the spring pre-
load; the longer distance A is, the lower
the spring preload.
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting dial in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting dial in di-
rection (b).
Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw
in direction (a). To decrease the com-
pression damping force and thereby
soften the compression damping, turn

TIP

To obtain a precise adjustment, it is ad-
visable to check the actual total number
of clicks or turns of each damping force
adjusting mechanism. This adjustment
range may not exactly match the spec-ifications listed due to small differences
in production.
WARNING

EWA10221
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.

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

Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.

Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.

Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamaha
dealer for any service.
EAU41940
EXUP system
This model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that regu-
lates the diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.
NOTICE

ECA15610
The EXUP system has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.

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.
TIP

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.
EAU44892
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.

OPERATION AND IMPORTANT RIDING POINTS
EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING

EWA10271
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.
EAU46632
TIP

This model is equipped with:

a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the multi-function display in-
dicates error code 30, but this is
not a malfunction. Turn the key to
“OFF” and then to “ON” to clear the
error code. Failing to do so will pre-
vent the engine from starting even
though the engine will crank when
pushing the start switch.

an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. In this case,
the multi-function display indicates
error code 70, but this is not a mal-
function. Push the start switch to
clear the error code and to restart
the engine.
EAU45123
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.
See page 3-19 for more informa-
tion.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
The following warning lights
should come on for a few seconds,
then go off.

Fuel level warning light

Coolant temperature warning light

Engine trouble warning light
NOTICE

ECA15482
If a warning light does not go off, see
page 3-2 for the corresponding
warning light circuit check.
2. Shift the transmission into the neu-
tral position. (See page 5-2.) The

neutral indicator light should come
on. If not, ask a Yamaha dealer to
check the electrical circuit.
3. Start the engine by pushing the
start switch.
NOTICE:
For maxi-
mum engine life, never acceler-
ate hard when the engine is
cold!

[ECA11041]

If the engine fails to start, release
the start switch, wait a few sec-
onds, and then try again. Each
starting attempt should be as short
as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one at-
tempt.
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.
TIP

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.
NOTICE

ECA10260

Even with the transmission inthe 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.

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.
EAU17023
0–1000 km (0–600 mi)
Avoid prolonged operation above 1/3
throttle.
NOTICE:
After 1000 km (600
mi) of operation, the engine oil must
be changed, and the oil filter car-
tridge or element replaced.

[ECA11282]

1000–1600 km (600–1000 mi)
Avoid prolonged operation above 1/2
throttle.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE

ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
