Sidestand
This 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
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 mo-
torcycle a lockout system to assist
the operator in fulfilling the respon-
sibility of retracting the sidestand.
Please check carefully the operating
instructions listed below and if there
is any indication of a malfunction,
return the motorcycle to a Yamaha
dealer immediately for repair.

EAU00683
Operating the motorcycle with ex-
cessively worn tires decrease riding
stability and can lead to loss of con-
trol. Have excessively worn tires re-
placed by a Yamaha dealer
immediately. Brakes, tires, and re-
lated wheel parts replacement
should be left to a Yamaha Service
Technician.
EAU00687
Wheels
To ensure maximum performance,
long service, and safe operation, note
the following:
lAlways inspect the wheels before
a ride. Check for cracks, bends, or
warpage of the wheels. If any ab-
normal condition exists in a wheel,
consult a Yamaha dealer. Do not
attempt even small repairs to the
wheel. If a wheel is deformed or
cracked, it must be replaced.
lTires 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.
lRide at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.

Inspecting the brake fluid
level
Insufficient 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 fill
when necessary.
Observe these precautions:
lWhen checking the fluid level,
make sure the top of the master
cylinder is level by turning the han-
dlebars.
1. Minimum level mark
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake perfor-
mance.
NOTE:
If DOT 4 is not available, DOT 3 can be
used.Recommended brake fluid: DOT 4
lRefill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
lBe 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.
lBrake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
lHave a Yamaha dealer check the
cause if the brake fluid level goes
down.

EAU00769
Drive chain lubrication
The chain consists of many parts which
work with each other. If the chain is not
maintained properly, it will wear out
quickly. Therefore, the chain must be
serviced regularly. This service is es-
pecially necessary when riding in dusty
areas. This motorcycle is equipped
with a sealed type chain. Steam clean-
ing, high-pressure washes, and sol-
vents can damage chain so do not use
these for cleaning it. Use only kerosene
to clean the drive chain. Wipe it dry,
and thoroughly lubricate it with SAE 30
~ 50W motor oil. Do not use any other
lubricants on the drive chain. They may
contain solvents that could damage the
sealed chain.
EC000097
CAUTION:
Be sure to oil the chain after wash-
ing the motorcycle or riding in the
rain.
