Spark plug inspectionThe spark plug is an important engine
component and should be inspected
periodically, preferably by a Yamaha
dealer. The condition of the spark plug
can indicate the condition of the en-
gine.
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. The spark
plugs should be periodically removed
and inspected because heat and de-
posits will cause any spark plug to
slowly break down and erode. If elec-
trode erosion becomes excessive, or if
carbon and other deposits are exces-
sive, the spark plug should be replaced
with the specified plug.
Before installing any spark plug, mea-
sure the electrode gap with a wire
thickness gauge and adjust it to specifi-
cation.When installing a spark plug, the gas-
ket surface should always be cleaned
and a new gasket used. Any grime
should be wiped off from the threads
and the spark plug tightened to the
specified torque.
NOTE:@ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4 to 1/2 turn
past finger tight. The spark plug should
be tightened to the specified torque as
soon as possible. @

Engine oilOil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. Warm up the engine for seve-
ral minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings. @2. Stop the engine and wait for a few
minutes. Check the oil level
through the level window located
at the lower part of the right side
crankcase cover.NOTE:@ Wait a few minutes until the oil level
settles before checking. @
3. The oil level should be between
the maximum and minimum
marks. If the level is low, fill the en-
gine with sufficient recommended
oil to reach the specified level.Engine oil and oil filter cartridge re-
placement
1. Warm up the engine for several
minutes.
2. Stop the engine. Place an oil pan
under the engine and remove the

NOTE:@ An oil filter wrench is available at a
nearby Yamaha dealer. @5. Reinstall the drain bolt and tighten
it to the specified torque.
6. Apply a light coat of engine oil to
the O-ring of new oil filter.NOTE:@ Make sure the O-ring is seated properly. @

CAUTION:@ l
Do not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.
l
Be sure no foreign material en-
ters the crankcase.

9. Start the engine and warm it up for
several minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.NOTE:@ After the engine is started, the oil level
indicator light should go off if the oil is at
the specified level. @

CAUTION:@ If the indicator light flickers or re-
mains on, immediately stop the en-
gine and consult with a Yamaha
dealer. @

Coolant1. Remove panel C. (See page 7-8
for removal and installation proce-
dures.)
2. Check the coolant level in the res-
ervoir tank when the engine is cold
as the coolant level will vary with
engine temperature. The coolant
level should be between the maxi-
mum and minimum marks.3. If the level is low, remove the rider
seat, open the reservoir tank cap,
and add coolant or distilled water
to the specified level. (See page
3-15 for rider seat removal and in-
stallation procedures.)
4. Install the reservoir tank cap and
rider seat.
5. Install the panel.

CAUTION:@ Hard water or salt water is harmful
to the engine. You may use distilled
water if you can’t get soft water. @NOTE:@ l
If water is added, have a Yamaha
dealer check the antifreeze con-
tent of the coolant as soon as pos-
sible.
l
Have a Yamaha dealer change
the coolant every two years.

pletely automatic. It is switched on
