6 2. Use the spark plug wrench in the
tool kit to remove the spark plugs
as shown.Inspection
The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate
the condition of the engine.
Normally, all spark plugs from the
same engine should have the same
color on the white insulator around the
center electrode. The ideal color at this
point is a medium-to-light tan color for a
motorcycle that is being ridden normal-
ly. If one spark plug shows a distinctly
different color, there could be some-
thing wrong with the engine.Do not attempt to diagnose such prob-
lems yourself. Instead, take the motor-
cycle to a Yamaha dealer. You should
periodically remove and inspect the
spark plugs because heat and deposits
will cause any spark plug to slowly
break down and erode. If electrode ero-
sion becomes excessive, or if carbon
and other deposits are excessive, you
should replace the spark plug with the
specified plug.

MOTORCYCLE CARE AND STORAGE

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. @
