EAU01008Troubleshooting
Although Yamaha motorcycles
receive a rigid inspection before ship-
ment from the factory, trouble may
occur during operation.
Any problem in the fuel, compres-
sion, or ignition systems can cause
poor starting and loss of power. The
troubleshooting chart describes a
quick, easy procedure for making
checks.
If your motorcycle requires any
repair, bring it to a Yamaha dealer.
The skilled technicians at a Yamaha
dealership have the tools, experi-
ence, and know-how to properly ser-
vice your motorcycle. Use only gen-
uine Yamaha parts on your
motorcycle. Imitation parts may look
like Yamaha parts, but they are often
inferior. Consequently, they have a
shorter service life and can lead to
expensive repair bills.

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Open the radiator cap as follows. Wait until the
engine has cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over
the radiator cap and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual
pressure to escape. When the hissing sound has stopped, press down on the cap while turning counterclock-
wise and remove it.
NOTE:
If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the rec-
ommended coolant as soon as possible.

Wait until the engine
has cooled.
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system. Check the coolant level in the
reservoir tank and/or radiator.

Care
The exposure of its technology
makes a motorcycle charming but
also vulnerable. Although high-quality
components are used, they are not
all rust-resistant. While a rusty
exhaust pipe may remain unnoticed
on a car, it does look unattractive on
a motorcycle. Frequent and proper
care, however, will keep your motor-
cycle looking good, extend its life and
maintain its performance. Moreover,
the warranty states that the vehicle
must be properly taken care of. For
all these reasons, it is recommended
that you observe the following clean-
ing and storing precautions.Before cleaning
1. Cover up the muffler outlet with a
plastic bag.
2. Make sure that all caps and cov-
ers as well as all electrical cou-
plers and connectors, including
the spark plug cap, are tightly
installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
tooth or bottle brush, but never
apply such products onto seals,
gaskets, sprockets, the drive
chain and wheel axles. Always
rinse the dirt and degreaser off
with water.Cleaning
After normal use
Remove dirt with warm water, a neu-
tral detergent and a soft clean
sponge, then rinse with plenty of
clean water. Use a brush for hard-to-
reach parts. Tougher dirt and insects
will come off more easily if the area is
covered with a wet cloth for a few
minutes before cleaning.

Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If you do use
such products for hard-to-
remove dirt, do not leave it on
any longer than instructed,
then thoroughly rinse it off
with water, immediately dry
the area and apply a corrosion
protection spray.

Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent
and water to clean plastic.
8 8
Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abra-
sive cleaning products, sol-
vent or thinner, fuel (gasoline),
rust removers or inhibitors,
brake fluid, antifreeze or elec-
trolyte.8 8
Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel bearings, swingarm
bearings, forks and brakes),
electric components (cou-
plers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
8 8
For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure they
do not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.After riding in the rain, near the sea
or on salt-sprayed roads
Since sea salt or salt sprayed on the
roads in the winter are extremely cor-
rosive in combination with water,
carry out the following steps after
each ride in the rain, near the sea or
on salt-sprayed roads. (Salt sprayed
in the winter may remain on the roads
well into spring.)
1. Clean your motorcycle with cold
water and soap after the engine
has cooled down.
ECA00012
cC
Do not use warm water since it
increases the corrosive action of
the salt.
2. Be sure to apply a corrosion pro-
tection spray on all (even
chrome- and nickel-plated) metal
surfaces to prevent corrosion.

After cleaning
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
induced discoloring of stainless-
steel exhaust systems can be
removed through polishing.)
4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all (even
chrome- and nickel-plated) metal
surfaces.
5. Use spray oil as a universal
cleaner to remove any remaining
dirt.
6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry complete-
ly before storing it or covering it.EWA00001
w
Make sure that there is no oil or
wax on the brakes and tires. If
necessary, clean the brake discs
and linings with a regular brake
disc cleaner or acetone, and wash
the tires with warm water and mild
soap. Then, carefully test the
motorcycle for its braking perfor-
mance and cornering behavior.

Apply spray oil and wax spar-
ingly and wipe off any excess.
8 8
Never apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care
product.
8 8
Avoid using abrasive polish-
ing compounds as they wear
away the paint.
NOTE:
Consult a Yamaha dealer for advice
on what products to use.

Storage
Short-term
Always store your motorcycle in a
cool, dry place and, if necessary, pro-
tect it against dust with a porous
cover.
ECA00014
cC
8
8
Storing the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp while it is
still wet will allow water and
humidity to seep in and cause
rust.
8 8
To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Drain the carburetor float cham-
ber by loosening the drain bolt;
this will prevent fuel deposits
from building up. Pour the
drained fuel into the fuel tank.
3. Only for motorcycles equipped
with a fuel cock which has an
“OFF” position: Turn the fuel
cock to “OFF”.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.a. Remove the spark plug cap and
spark plug.
b. Pour a teaspoonful of engine oil
into the spark plug bore.
c. Install the spark plug cap onto
the spark plug and place the
spark plug on the cylinder head
so that the electrodes are
grounded. (This will limit spark-
ing during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
e. Remove the spark plug cap from
the spark plug, install the spark
plug and then the spark plug
cap.
EWA00003

When turning the engine over, be
sure to ground the spark plug elec-
trodes to prevent damage or injury
from sparking.

6. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
7. Check and, if necessary, correct
the tire air pressure, then raise
the motorcycle so that both of its
wheels are off the ground.
Alternatively, turn the wheels a
little every month in order to pre-
vent the tires from becoming
degraded in one spot.
8. Cover up the muffler outlet with a
plastic bag to prevent moisture
from entering.9. Remove the battery and fully
charge it. Store it in a cool, dry
place and recharge it once a
month. Do not store the battery
in an excessively cold or warm
place (less than 0°C or more
than 30°C). For more informa-
tion, see “Battery storage” in the
chapter “PERIODIC MAINTE-
NANCE AND MINOR
REPAIRS”.
NOTE:
Make any necessary repairs before
storing the motorcycle.
