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. @4. Install the spark plug caps.

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 sev-
eral 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. @

the oil level through the level win-
dow 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
maximum and minimum marks. If
the level is low, fill the engine with
sufficient oil to reach the specified
level.Engine oil and oil filter cartridge re-
placement
1. Remove cowling A. (See page 6-5
for removal and installation proce-
dures.)
2. Remove the cowling stay.
3. Warm up the engine for several
minutes.
4. Stop the engine. Place an oil pan
under the engine and remove the
oil filler cap.
5. Remove the drain bolt and drain
the oil.6. Remove the oil filter by using an oil
filter wrench.
NOTE:@ An oil filter wrench is available at a
nearby Yamaha dealer. @7. Reinstall the drain bolt and tighten
it to the specified torque.

68. Apply a light coat of engine oil to
the O-ring of the new oil filter.
NOTE:@ Make sure the O-ring is seated proper-
ly. @9. Install the oil filter and tighten it to
the specified torque with an oil fil-
ter wrench.NOTE:When installing the oil filter, tighten it to
the proper torque by using a torque
wrench.
10. Fill the engine with sufficient oil to
reach the specified level. Install
the oil filler cap and tighten it.

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.
@
11. 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. @12. Install the cowling stay and cowl-
ing.

l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake perfor-
mance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
Have a Yamaha dealer check the
cause if the brake fluid level goes
down.
EAU00742
Brake fluid replacementThe brake fluid should be replaced only
by trained Yamaha service personnel.
Have the Yamaha dealer replace the
following components during periodic
maintenance or when they are dam-
aged or leaking:l
oil seals (every two years)
l
brake hoses (every four years)

@ Securely support the motorcycle so
there is no danger of it falling over. @Check for scratches or damage on the
inner tube and excessive oil leakage
from the front fork.
Operation check
1. Place the motorcycle on a level
place.
2. Hold the motorcycle in an upright
position and apply the front brake.
3. Push down hard on the handle-
bars several times and check if the
fork rebounds smoothly.

ment is found with the front fork,
consult a Yamaha dealer. @
