cornering (insufficient lean angle
for the speed). Never travel faster
than warranted by conditions.

Ride cautiously in unfamiliar ar-
eas. You may encounter hidden
obstacles that could cause an ac-
cident.

The posture of the operator is im-
portant for proper control. The op-
erator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the motorcy-
cle.

Never ride under the influence of
alcohol or other drugs.

Be sure the transmission is in neu-
tral before starting the engine.
Protective apparel
The majority of fatalities from motorcy-
cle accidents are the result of head in-
juries. The use of a safety helmet is the
single most critical factor in the preven-
tion or reduction of head injuries.

Always wear an approved helmet.

Wear a face shield or goggles.
Wind in your unprotected eyescould contribute to an impairment
of vision that could delay seeing a
hazard.

The use of a jacket, heavy boots,
trousers, gloves, etc., is effective in
preventing or reducing abrasions
or lacerations.

Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, or wheels
and cause injury or an accident.

Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust sys-
tem become very hot during or af-
ter operation and can cause burns.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing car-
bon monoxide can cause headaches,
dizziness, drowsiness, nausea, confu-
sion, and eventually death.
Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be
present even if you do not see or smell
any engine exhaust. Deadly levels of
carbon monoxide can collect rapidlyand you can quickly be overcome and
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poison-
ing, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.

Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.

Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.

Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
Adding accessories to your motorcycle
can adversely affect stability and han-
dling if the weight distribution of the mo-
torcycle is changed. To avoid the

9Tire information
This motorcycle is equipped with spoke
wheels and tube tires.
WARNING

EWA10461
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, which
could lead to an accident.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
WARNING

EWA14390

Have a Yamaha dealer replace
excessively worn tires. Operat-
ing the motorcycle with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.

The replacement of all
wheel-and brake-related parts,
including the tires, should be
left to a Yamaha dealer, who has
the necessary professional
knowledge and experience.

It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
very carefully and replace it as
soon as possible with a
high-quality product.
EAU21940
Spoke wheels
To maximize the performance, durabil-
ity, and safe operation of your motorcy-
cle, note the following points regarding
the specified wheels.

The wheel rims should be checked
for cracks, bends or warpage, and
the spokes for looseness or dam-
age before each ride. If any dam-
age is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.

The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.

Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics.

Adjusting the brake pedal free
play
The brake pedal free play should mea-
sure 10.0–20.0 mm (0.39–0.79 in) at
the brake pedal end as shown. Period-
ically check the brake pedal free play
and, if necessary, adjust it as follows.
To increase the brake pedal free play,
turn the adjusting nut at the brake rod in
direction (a). To decrease the brake
pedal free play, turn the adjusting nut in
direction (b).
WARNING

EWA10680

After adjusting the drive chain
slack or removing and installing
the rear wheel, always check the
brake pedal free play.

If proper adjustment cannot be
obtained as described, have a
Yamaha dealer make this ad-
justment.

After adjusting the brake pedal
free play, check the operation of
the brake light.
EAU41052
Checking the front and rear
brake shoes
The front and rear brake shoes must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
TIP

The wheels must be removed to check
brake shoe lining thickness.

To remove the front wheel: See
page 6-23.

To remove the rear wheel: See
page 6-25.

If the lining thickness of a brake shoe is
less than 1.5 mm (0.06 in), have a
Yamaha dealer replace the brake
shoes as a set.
TIP

Be sure to measure the brake lining at
the thinnest portion.
EAU22760
Drive chain slack
The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU22773
To check the drive chain slack
1. Place the motorcycle on the side-
stand.
TIP

When checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.
2. Shift the transmission into the neu-
tral position.
3. Move the rear wheel by pushing
the motorcycle to locate the tight-
est portion of the drive chain, and
then measure the drive chain slack
as shown.4. If the drive chain slack is incorrect,
adjust it as follows.
EAU40111
To adjust the drive chain slack
1. Loosen the brake pedal free play
adjusting nut, axle nut, and locknut
at each end of the swingarm.
Drive chain slack:
40.0–53.0 mm (1.57–2.09 in)

2. To tighten the drive chain, turn the
drive chain slack adjusting nut at
each end of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting nut at each end
of the swingarm in direction (b),
and then push the rear wheel for-
ward.
NOTICE:
Improper drive
chain slack will overload the en-
gine as well as other vital parts
of the motorcycle and can lead
to chain slippage or breakage.
To prevent this from occurring,
keep the drive chain slack with-in the specified limits.

[ECA10571]

TIP

Using the alignment marks on each
side of the swingarm, make sure that
both adjusting nuts are in the same po-
sition for proper wheel alignment.
3. Tighten both locknuts and the axle
nut to the specified torques.4. Adjust the brake pedal free play.

NOTICE

ECA10590
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or re-
pair it.
EAU23282
Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the operation
of the steering must be checked as fol-
lows at the intervals specified in the pe-
riodic maintenance and lubrication
chart.
1. Place a stand under the engine to
raise the front wheel off the
ground. (See page 6-1 for more in-
formation.)
WARNING! To avoid
injury, securely support the ve-
hicle so there is no danger of it
falling over.
[EWA10751]

2. Hold the lower ends of the front
fork legs and try to move them for-
ward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the steering.
