Adjusting rear shock
absorber preloadThis shock absorber is equipped with a
spring preload adjusting nut. Use the
special wrench located in the owner’s
tool kit to adjust the spring preload.
1. Loosen the locknut.2. Turn the adjusting nut in
direction
a to increase spring pre-
load and in direction
b to de-
crease spring preload. The spring
preload is determined by the
spring set length.
Shortening the spring set length
increases spring preload, length-
ening the spring set length de-
creases spring preload.

WARNING
@ This shock absorber contains high-
ly pressurized nitrogen gas. Read
and understand the following infor-
mation before handling the shock
absorber. The manufacturer cannot
be held responsible for property
damage or personal injury that may
result from improper handling.l
Do not tamper with or attempt to
open the cylinder assembly.
l
Do not subject the shock ab-
sorber to an open flame or other
high heat source. This may
cause the unit to explode due to
excessive gas pressure.
l
Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
l
Take your shock absorber to a
Yamaha dealer for any service.

SidestandThis model is equipped with an ignition
circuit cut-off system. The motorcycle
must not be ridden when the sidestand
is down. The sidestand is located on
the left side of the frame. (Refer to
page 5-1 for an explanation of this sys-
tem.)
EW000044
WARNING
@ This motorcycle must not be operat-
ed with the sidestand in the down
position. If the stand is not properly
retracted, it could contact the
ground and distract the operator, re-
sulting in a possible loss of control.
Yamaha has designed into this
motorcycle a lockout system to as-
sist the operator in fulfilling the re-
sponsibility of retracting the
sidestand. Please check carefully
the operating instructions listed be-
low and if there is any indication of a
malfunction, return the motorcycle
to a Yamaha dealer immediately for
repair. @

WheelsTo ensure maximum performance,
long service, and safe operation, note
the following:l
Always inspect the wheels before
a ride. Check for cracks, bends or
warpage of the wheel. Be sure the
spokes are tight and undamaged.
If any abnormal condition exists in
a wheel, consult a Yamaha dealer.
Do not attempt even small repairs
to the wheel. If a wheel is de-
formed or cracked, it must be re-
placed.
l
Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics, and short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.

WARNING
@ l
Check the brake lever free play.
Be sure the brake is working
properly.
l
A soft or spongy feeling in the
brake lever can indicate the
presence of air in the brake sys-
tem. This air must be removed
by bleeding the brake system
before the motorcycle is operat-
ed. Air in the system will cause
greatly diminished braking ca-
pability and can result in loss of
control and an accident. Have a
Yamaha dealer inspect and
bleed the system if necessary.

Inspecting the brake fluid
levelInsufficient brake fluid may let air enter
the brake system, possibly causing the
brakes to become ineffective.
Before riding, check that the brake fluid
is above the minimum level and replen-
ish when necessary.
Observe these precautions:l
When checking the fluid level,
make sure the top of the master
cylinder is level by turning the han-
dlebars.
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake perfor-
mance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
Have a Yamaha dealer check the
cause if the brake fluid level goes
down.
