Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
motorcycle with excessively
worn tires decreases riding
stability and can lead to loss of
control.
The replacement of all wheel-
and brake-related parts, inclu-ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.
It is not recommended to patch
a punctured tube. If unavoida-
ble, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.
EAU21942
Spoke wheelsEWA10610
The wheels on this model are not
designed for use with tubeless
tires. Do not attempt to use tube-
less tires on this model.
To maximize the performance, durabi-
lity, and safe operation of your
motorcycle, note the following points
regarding the specified wheels.
The wheel rims should be chec-
ked for cracks, bends or warpa-
ge, and the spokes for looseness
or damage before each ride. If
any damage is found, have a
Yamaha dealer replace the whe-
el. Do not attempt even the sma-
llest repair to the wheel. A defor-
med 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
handling characteristics, and a
shortened tire life.

Drive chain slack
The drive chain slack should be chec-
ked before each ride and adjusted if
necessary.
EAU22783
To check the drive chain slack
1. Drive chain slack
1. Place the motorcycle on the
sidestand.
TIP
When checking and adjusting the dri-
ve chain slack, there should be no
weight on the motorcycle.
2. Shift the transmission into the
neutral position.3. Move the rear wheel by pushing
the motorcycle to locate the tigh-
test portion of the drive chain,
and then measure the drive chain
slack as shown.
4. If the drive chain slack is inco-
rrect, adjust it as follows.
TIP
When checking the drive chain slack,
the chain tensioner should not be tou-
ching the drive chain.
EAU34316
To adjust the drive chain slack
1. Loosen the axle nut and the lock-
nut on each side of the swin-
garm.
1. Wheel axle
2. Drive chain slack adjusting bolt
3. Locknut
4. Alignment marks
2. To tighten the drive chain, turn
the drive chain slack adjusting
bolt on each side of the swin-
garm in direction (a). To loosen
the drive chain, turn the adjusting
bolt on each side of the swin-
garm in direction (b), and then
push the rear wheel forward.
NOTICE: Improper drive chain
slack will overload the engine
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 wit-
hin the specified limits.

Cleaning and lubricating the
drive chain
The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly
wear out, especially when riding in
dusty or wet areas. Service the drive
chain as follows.
ECA10583
The drive chain must be lubricated
after washing the motorcycle,
riding in the rain or riding in wet
areas.
1. Clean the drive chain with kero-
sene and a small soft brush.
NOTICE: To prevent damaging
the O-rings, do not clean the
drive chain with steam clea-
ners, high-pressure washers or
inappropriate solvents.
[ECA11121]
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant. NOTICE: Do not use
engine oil or any other lubri-cants for the drive chain, as
they may contain substances
that could damage the O-rings.

Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the opera-
tion of the steering must be checked
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
1. Place a stand under the engine to
raise the front wheel off the
ground. (See page 6-35 for more
information.) WARNING! To
avoid injury, securely support
the vehicle so there is no dan-
ger of it falling over.
[EWA10751]
2. Hold the lower ends of the front
fork legs and try to move them
forward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the stee-
ring.

Since this model is not equipped with
a centerstand, follow these precau-
tions when removing the front and
rear wheel or performing other main-
tenance requiring the motorcycle to
stand upright.
Check that the motorcycle is in a sta-
ble and level position before starting
any maintenance. A strong wooden
box can be placed under the engine
for added stability.
To service the front wheel
1. Stabilize the rear of the motorcy-
cle by using a motorcycle stand
or, if an additional motorcycle
stand is not available, by placing
a jack under the frame in front of
the rear wheel.
2. Raise the front wheel off the
ground by using a motorcycle
stand.
To service the rear wheel
Raise the rear wheel off the ground by
using a motorcycle stand or, if a
motorcycle stand is not available, byplacing a jack either under each side
of the frame in front of the rear wheel
or under each side of the swingarm.

Troubleshooting
Although Yamaha motorcycles recei-
ve a thorough inspection before ship-
ment from the factory, trouble may
occur during operation. Any problem
in the fuel, compression, or ignition
systems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcy-
cle require any repair, take it to a
Yamaha dealer, whose skilled techni-
cians have the necessary tools, expe-
rience, and know-how to service the
motorcycle properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
EWA15141
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
