6 Battery storage
When the motorcycle is not used for a
month or longer, remove the battery,
fully charge it and store it in a cool, dry
place.
EC000102
CAUTION:@ l
Completely recharge the bat-
tery before storing. Storing a
discharged battery can cause
permanent battery damage.
l
Use a battery charger designed
for a sealed-type (MF) battery.
Using a conventional battery
charger will cause battery dam-
age. If you do not have a sealed-
type battery charger, contact
your Yamaha dealer.
l
Always make sure the connec-
tions are correct when reinstall-
ing the battery.

Fuse replacementOne fuse box is located under the rid-
er’s seat and the other is located be-
hind cowling B. (See page 6-5.) If any
fuse is blown, turn off the main switch
and the switch of the circuit in question.
Install a new fuse of specified amper-
age. Turn on the switches and see if
the electrical device operates. If the
fuse immediately blows again, consult
a Yamaha dealer.

CAUTION:@ Do not use fuses of higher amper-
age rating than those recommend-
ed. Substitution of a fuse of
improper rating can cause extensive

TroubleshootingAlthough Yamaha motorcycles receive
a rigid inspection before shipment from
the factory, trouble may occur during
operation.
Any problem in the fuel, compression,
or ignition systems can cause poor
starting and loss of power. The trouble-
shooting 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, experience, and know-
how to properly service your motor-
cycle. Use only genuine Yamaha parts
on your motorcycle. Imitation parts may
look like Yamaha parts, but they are of-
ten inferior. Consequently, they have a
shorter service life and can lead to ex-
pensive repair bills.

Engine overheating
EW000070
WARNING
@ 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 counterclockwise 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 recom-
mended coolant as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir tank and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See NOTE.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system.

7a. Remove the spark plug caps and
spark plugs.
b. Pour a teaspoonful of engine oil
into each spark plug bore.
c. Install the spark plug caps onto the
spark plugs and place the spark
plugs on the cylinder head so that
the electrodes are grounded. (This
will limit sparking during the next
step.)
d. Turn the engine over several times
with the starter. (This will coat the
cylinder walls with oil.)
e. Remove the spark plug caps from
the spark plugs, install the spark
plugs and then the spark plug
caps.
EWA00003
WARNING
@ 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. Alterna-
tively, turn the wheels a little every
month in order to prevent 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 information, see
“Battery storage” in the chapter
“PERIODIC MAINTENANCE AND
MINOR REPAIRS”.
NOTE:@ Make any necessary repairs before
storing the motorcycle. @
