6Installation
1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the gasket surface. Wipe off
any grime from the threads.3. Install the spark plug and tighten it
to the specified torque.
NOTE:@ If a torque wrench is not available when
you are installing a spark plug, a good
estimate of the correct torque is 1/4 to
1/2 turn past finger tight. Have the
spark plug tightened to the specified
torque as soon as possible. @
EAU01703
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. @

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
oil filler cap.
3. Remove the drain bolt and drain
the oil.
4. Remove the oil filter by using an oil
filter wrench.
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 proper-
ly. @

67. Install the new oil filter and tighten
it to the specified torque with an oil
filter wrench.
NOTE:@ When installing the oil filter, tighten it to
the proper torque by using a torque
wrench. @
8. Fill the engine with sufficient rec-
ommended oil. Install the oil filler
cap and tighten it.
EC000066
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.
EC000067
CAUTION:@ If the indicator light flickers or re-
mains on, immediately stop the en-
gine and consult with a Yamaha
dealer. @
