Checking the spark plugs The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal col-
or when the motorcycle is ridden nor-
mally), and all spark plugs installed inthe engine should have the same color.
If any spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the motorcycle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.
Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
NOTE:@ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible. @

CAUTION:@ Do not use any tools to remove or
install the spark plug cap, otherwise
the ignition coil coupler may get
damaged. The spark plug cap may
be difficult to remove because the
rubber seal on the end of the cap fits
tightly. To remove the spark plug
cap, simply twist it back and forth
while pulling it out; to install it, twist
it back and forth while pushing it in. @

Engine oil and oil filter
cartridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied 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 posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. @2. Remove the rider seat. (See page
3-12 for rider seat removal and in-
stallation procedures.)3. Start the engine, warm it up until
the engine oil has reached a nor-
mal temperature of 60 °C, let it
continue to idle for ten seconds,
and then turn the engine off.
NOTE:@ To achieve the proper engine oil tem-
perature for an accurate oil level read-
ing, the engine must have first
completely cooled down, and then
warmed up again for several minutes to
normal operating temperature. @4. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.NOTE:@ The engine oil should be between the
minimum and maximum level marks. @

65. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
NOTE:@ When adding oil, be careful not to over-
fill the engine; the oil level rises faster
starting from the half level portion on
the dipstick. @6. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
7. Install the rider seat.

curely tightened, otherwise oil may

running. @

6 To change the engine oil
(with or without oil filter cartridge
replacement)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the oil tank
to collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the oil tank.
NOTE:@ Skip steps 4–8 if the oil filter cartridge is
not being replaced. @4. Place an oil pan under the engine
to correct the used oil.
5. Remove the engine oil drain bolt to
drain the oil from the crankcase.
6. Remove the oil filter cartridge with
an oil filter wrench.NOTE:@ An oil filter wrench is available at a
Yamaha dealer. @
7. Apply a thin coat of engine oil to
the O-ring of the new oil filter car-
tridge.NOTE:@ Make sure that the O-ring is properly
seated. @8. Install the new oil filter cartridge,
and then tighten it to the specified
torque with a torque wrench.

69. Install the engine oil drain bolts,
and then tighten them to the spec-
ified torque.
10. Pour only 2.5 L of the specified
amount of recommended engine
oil through the filler hole, insert the
dipstick, and then tighten the oil
filler cap.
11. Start the engine, rev it several
times, and then turn it off.
12. Remove the engine oil filler cap,
and then gradually fill the oil tank
with the remaining oil quantity
while regularly checking the oil
level on the dipstick.
EC000072
CAUTION:@ l
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives with
the oil or use oils of a higher
grade than “CD”. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
l
Make sure that no foreign mate-
rial enters the crankcase.

13. Install the engine oil filler cap.
14. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
15. Turn the engine off, and then
check the oil level and correct it if
necessary. Tightening torque:
