 Bran d-new tires can have a rel-
atively poor g rip on certain roa d
surfaces until they have  been

Cast wheelsTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
 The wheel rims should be
checked for cracks, bends, warp-
age or other damage before each
ride. If any damage is found, have
a Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A de-
formed 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.

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU60046
To check the  drive chain slack
1. Place the motorcycle on the side- stand.TIPWhen checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.2. Shift the transmission into the neutral position.
3. Push down on the drive chain un- der the end of the drive chain
guard.
4. Measure distance A between the drive chain guard and the center
of the chain as shown. 5. If distance A is incorrect, adjust it
as follows.  NOTICE: Improper
d rive chain slack will overloa d
the en gine as well as other vital
parts of the motorcycle an d can
lea d to chain slippa ge or b reak-
a g e. If d istance A is more than
58.0 mm (2.28 in), the chain can
d amag e the frame, swin garm,
an d other parts. To prevent this
from occurrin g, keep the  drive
chain slack within the specifie d
limits.

Consult a Yamaha dealer before ad-
justing the drive chain slack. 1. Loosen the locknut at each end of the swingarm, and then loosen the
axle nut.
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),

Checkin g the front forkThe condition and operation of the
front fork must be checked as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
To check the con dition
Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.  WARNING! To avoi d injury,
securely support the vehicle so
there is no  dan ger of it fallin g
over.

2. While applying the front brake, push down hard on the handle-
bars several times to check if the
front fork compresses and re-
bounds smoothly.

If any d amage is foun d or the front
fork  does not operate smoothly,
have a Yamaha  dealer check or re-
pair it.

Checkin g the steerin gWorn 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
periodic maintenance and lubrication
chart.
1. Raise the front wheel off the ground. (See page 6-35.)

the battery lead connections need to
be checked and, if necessary, tight-
ened.

Supportin g the motorcycleSince this model is not equipped with a
centerstand, use maintenance stands
when removing the front or rear wheel
or when performing other maintenance
that requires the motorcycle to stand
up right.
Check that the motorcycle is in a stable
and level position before starting any
maintenance.
EAU25872
Trou bleshootin gAlthough Yamaha motorcycles receive
a thorough inspection before shipment
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 motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, 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.
WARNING
EWA15142
When checkin g the fuel system,  do
not smoke, an d make sure there are
no open flames or sparks in the ar-
ea, inclu din g pilot lig hts from water heaters or furnaces. Gasoline or

Some mo dels are equipped  with

sure to consult a Yamaha  dealer for
a d vice on what prod ucts to use be-
fore cleanin g the vehicle. Usin g a

CareWhile the open design of a motorcycle
reveals the attractiveness of the tech-
nology, it also makes it more vulnera-
ble. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go un-
noticed on a car, however, it detracts
from the overall appearance of a mo-
torcycle. Frequent and proper care
does not only comply with the terms of
the warranty, but it will also keep your
motorcycle looking good, extend its
life and optimize its performance.
Before cleanin g
1. Cover the muffler outlet with a plastic bag after the engine has
cooled down.
2. Make sure that all caps and cov- ers as well as all electrical cou-
plers and connectors, including
the spark plug caps, are tightly in-
stalled.
3. Remove extremely stubborn dirt, like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod- ucts onto seals, gaskets, sprock-
ets, the drive chain and wheel
axles. Always rinse the dirt and
degreaser off with water.
Cleanin g
NOTICE
ECA10773
Avoi d usin g stron g aci dic wheel
cleaners, especially on spoked
wheels. If such pro ducts are
use d on har d-to-remove  dirt,  do
not leave the cleaner on the af-
fected  area any lon ger than in-
structed . Also, thorou ghly rinse
the area off with water, immed i-
ately  dry it, an d then apply a cor-
rosion protection spray.
 Improper cleanin g can d amage
plastic parts (such as cowlin gs,
panels, win dshiel ds, hea dlig ht
lenses, meter lenses, etc.) an d
the mufflers. Use only a soft,
clean cloth or spon ge with wa-
ter to clean plastic. However, if
the plastic parts cannot  be thor-
ou ghly cleaned  with water,  di-
lute d mil d d eter gent with water
may  be used . Be sure to rinse

plenty of water, as it is harmful
to plastic parts.
 Do not use any harsh chemical
prod ucts on plastic parts. Be
sure to avoi d using  cloths or
spon ges which have  been in
contact with stron g or a brasive
cleanin g prod ucts, solvent or
thinner, fuel ( gasoline), rust re-
movers or inhi bitors,  brake flui d,
antifreeze or electrolyte.
 Do not use hi gh-pressure wash-
ers or steam-jet cleaners since
they cause water seepa ge an d
d eterioration in the followin g ar-
eas: seals (of wheel an d swin g-
arm  bearin gs, fork an d b rakes),
electric components (couplers,
connectors, instruments,
switches an d lig hts),  breather
hoses an d vents.
 For motorcycles equippe d with
a win dshield : Do not use stron g
cleaners or har d spon ges as
they will cause  dullin g
 or
scrat
ching . Some cleanin g
compoun ds for plastic may
leave scratches on the win d- shield
. Test the pro duct on a
small hidden part of the win d-
shield  to make sure that it  does
not leave any marks. If the win d-
shield  is scratche d, use a quality
plastic polishin g compoun d af-
ter washin g.
After normal useRemove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
After riding in the rain, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on roads
during winter are extremely corrosive
in combination with water, carry out
the following steps after each ride in
the rain, near the sea or on salt-
sprayed roads.
TIPSalt sprayed on roads in the winter
may remain well into spring.1. Clean the motorcycle with cold
water and a mild detergent, after
the engine has cooled down.
NOTICE:  Do not use warm wa-
ter since it increases the corro-
sive action of the salt.
 [ECA10792]
2. Apply a corrosion protection spray on all metal, including chrome-
and nickel-plated, surfaces to pre-
vent corrosion.
After cleanin g
1. Dry the motorcycle with a chamois or an absorbing cloth.
2. Immediately dry the drive chain and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
