Troubleshooting
Although Yamaha motor\fy\fles re\feive
a thorough inspe\ftion before shipment
from the fa\ftory, trouble may o\f\fur
during operation. Any problem in the
fuel, \fompression, or ignition systems,
for example, \fan \fause poor starting
and loss of po\ber.
The follo\bing troubleshooting \fharts
represent qui\fk and easy pro\fedures
for \fhe\fking these vital systems your-
self. Ho\bever, should your motor\fy\fle
require any repair, take it to a Yamaha
dealer, \bhose skilled te\fhni\fians have
the ne\fessary tools, experien\fe, and
kno\b-ho\b to servi\fe the motor\fy\fle
properly.
Use only genuine Yamaha repla\fe-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter servi\fe life and
\fan lead to expensive repair bills.
EWA15141
W\fRNING0
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from wa-
ter heaters or furnaces. Gasoline or
gasoline vapors can ignite or ex-
plode, causing severe injury or
property damage.

●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 cau\Mse serious injury. Be sure to wait until th\Me engine has coole\Md.
●\ffter removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.

Care
While the ope\f desig\f o\b a motorcycle
reveals the attractive\fess o\b the tech-
\fology, it also makes it more vul\fera-
ble. Rust a\fd corrosio\f ca\f develop
eve\f i\b high-quality compo\fe\fts are
used. A rusty exhaust pipe may go u\f-
\foticed o\f a car, however, it detracts
\brom the overall appeara\fce o\b a mo-
torcycle. Freque\ft a\fd proper care
does \fot o\fly comply with the terms o\b
the warra\fty, but it will also keep your
motorcycle looki\fg good, exte\fd its
li\be a\fd optimize its per\borma\fce.
Before cleaning 1. Cover the mu\b\bler outlet with a plastic bag a\bter the e\fgi\fe has
cooled dow\f.
2. Make sure that all caps a\fd cov- ers as well as all electrical cou-
plers a\fd co\f\fectors, i\fcludi\fg
the spark plug cap, are tightly i\f-
stalled. 3. Remove extremely stubbor\f dirt,
like oil bur\ft o\fto the cra\fkcase,
with a degreasi\fg age\ft a\fd a
brush, but \fever apply such prod-
ucts o\fto seals, gaskets, sprockets,
the drive chai\f a\fd wheel axles. Al-
ways ri\fse the dirt a\fd degreaser
o\b\b with water.
Cleaning
ECA10772
NOTICE
●Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If such prod-
ucts are used on hard-to-re-
move dirt, do not leave the
cleaner on the affected area
any longer than instructed. Al-
so, thoroughly rinse the area
off with water, immediately dry
it, and then apply a corrosion
protection spray.
●Improper cleaning can damage
plastic parts (such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc.) and
the mufflers. Use only a soft,
clean cloth or sponge with wa- ter to clean plastic. However, if
the plastic parts cannot be
thoroughly cleaned with water,
diluted mild detergent with wa-
ter may be used. Be sure to
rinse off any detergent residue
using plenty of water, as it is
harmful to plastic p\5arts.
●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 abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.
●Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the fol-
lowing areas: seals (of wheel
and swingarm bearings, fork
and brakes), electric compo-
nents (couplers, connectors,
instruments, switches and
lights), breather hoses and
vents.

●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 plastic may
leave scratches on the wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure that it does
not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing\ .After normal use
Remove d\frt w\fth warm water, a m\fld
deter\bent, and a soft, clean spon\be,
and then r\fnse thorou\bhly w\fth clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn d\frt
and \fnsects w\fll come off more eas\fly \ff
the area \fs covered w\fth a wet cloth for
a few m\fnutes before clean\fn\b.
After r\fd\fn\b \fn the ra\fn, near the sea
or on salt-sprayed roads
S\fnce sea salt or salt sprayed on roads
dur\fn\b w\fnter are extremely corros\fve
\fn comb\fnat\fon w\fth water, carry out
the follow\fn\b steps after each r\fde \fn
the ra\fn, near the sea or on salt-
sprayed roads.
TIP
Salt sprayed on roads \fn the w\fnter
may rema\fn well \fnto spr\fn\b.
1. Clean the motorcycle w\fth cold water and a m\fld deter\bent, after
the en\b\fne has cooled down. NO-
TICE: Do not use warm water
since it increases the corrosive
action of the salt. 2. Apply a corros\fon protect\fon
spray on all metal, \fnclud\fn\b
chrome- and n\fckel-plated, sur-
faces to prevent corros\fon.
\ffter cleaning 1. Dr y the motorcycle w\fth a chamo\fs or an absor\db\fn\b cloth.
2. Immed\fately dry the dr\fve cha\fn and lubr\fcate \ft to prevent \ft from
rust\fn\b.
3. Use a chrome pol\fsh to sh\fne chrome, alum\fnum and sta\fnless-
steel parts, \fnclud\fn\b the exhaust
system. (Even the thermally \fn-
duced d\fscolor\fn\b of sta\fnless-
steel exhaust systems can be re-
moved throu\bh pol\fsh\fn\b.)\d
4. To prevent corros\fon, \ft \fs recom- mended to apply a corros\fon pro-
tect\fon spray on all metal, \fnclud-
\fn\b chrome- and n\fckel-plated,
surfaces.
5. Use spray o\fl as a un\fversal clean- er to remove any rema\fn\fn\b d\frt.
6. Touch up m\fnor pa\fnt dama\be caused by stones, etc.
7. Wax all pa\fnted surfaces.

Long-term
Before storing your motorcycle for se\f-
eral months:\b. Follow all the instructions in the “Care” section of this ch\lapter.
2. Fill up the fuel tank and add fuel stabilizer (if a\failable) to pre\fent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to protect the cylinder, piston rings,
etc. from corrosion.a. Remo\fe 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 then place
the spark plug on the cylinder
head so that the electrodes
are grounded. (This will limit
sparking during the next step.)
d. Turn the engine o\fer se\feral times with the starter. (This will
coat the cylinder wall with oil.)
e. Remo\fe the spark plug cap from the spark plug, and then
install the spark plug and the
spark plug cap. W\fRNIN\b! To prevent damage or injury
from sparking, make sure to
ground the spark plug elec-
trodes while turning the en-
gine over.
4. Lubricate all control cables and the pi\foting points of all le\fers
and pedals as well as of the side-
stand/centerstand.\l
5. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alter-
nati\fely, turn the wheels a little
e\fery month in order to pre\fent
the tires from becoming degraded
in one spot.
6. Co\fer the muffler outlets with plastic bags to pre\fent moisture
from entering them. 7. Remo\fe the battery and fully
charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessi\fely cold or warm place [less
than 0 °C (30 °F) or more than 30
°C (90 °F)]. For more information
on storing the batter y, see
page 7-3\b.
TIP
Make any necessary repairs before
storing the motorcycle.
