Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN,
GEOGRAPHICAL LOCATION, AND
INDIVIDUAL USE, THE MAINTE-
NANCE INTERVALS MAY NEED TO
BE SHORTENED.

Checking the spark plugsThe spark plugs are important engine
components, which are easy to
check. Since heat and deposits will
cause any spark plug to slowly erode,
the spark plugs should be removed
and checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plugs can reveal the condition
of the engine.
To remove a spark plug
1.Remove the spark plug cap.1.Spark plug cap

To install a spark plug
1.Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
2.Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3.Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.

2.Remove the spark plug as
shown, with the spark plug
wrench included in the ownerÕs
tool kit.1.Spark plug wrench
Specified spark plug:
CR7HSA (NGK) or
U22FSR-U (DENSO)
To check the spark plugs
1.Check that the porcelain insulator
around the center electrode on
each spark plug is a medium-to-
light tan (the ideal color when the
motorcycle is ridden normally).
2.Check that all spark plugs
installed in the engine have the
same color.NOTE:
If any spark plug shows a distinctly
different color, the engine could be
defective. Do not attempt to diagnose
such problems yourself. Instead,
have a Yamaha dealer check the
motorcycle.3.Check each spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and
replace it if necessary.

NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4Ð1/2 turn past finger tight.
However, the spark plug should be
tightened to the specified torque as
soon as possible.4.Install the spark plug cap. Tightening torque:
Spark plug:
12.5 Nm (1.25 m0kg)

Engine oil and oil filter
elementThe engine oil level should be
checked before each ride. In addition,
the oil must be changed and the oil
filter element replaced at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the engine oil level
1.Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:
Make sure that the motorcycle is
positioned straight up when checking
the oil level. A slight tilt to the side
can result in a false reading.2.Start the engine, warm it up for
several minutes, and then turn it
off.3.Wait a few minutes until the oil
settles, and then check the oil
level through the check window
located at the bottom-right side
of the crankcase.
NOTE:
The engine oil should be between the
minimum and maximum level marks.4.If the engine oil is below the min-
imum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
