* Since these items require special tools, data and technical skills, they should be serviced by a Yamaha dealer.
EAU02970*
NOTE:@ l
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
l
Hydraulic brake system
• When disassembling the master cylinder or caliper cylinder, always replace the brake fluid. Check the brake fluid level
regularly and fill as required.
• Replace the oil seals on the inner parts of the master cylinder and caliper cylinder every two years.
• Replace the brake hoses every four years or if cracked or damaged.

6 2. Use the spark plug wrench in the
tool kit to remove the spark plugs
as shown.Inspection
The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate
the condition of the engine.
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. You should
periodically remove and inspect the
spark plugs because heat and deposits
will cause any spark plug to slowly
break down and erode. If electrode ero-
sion becomes excessive, or if carbon
and other deposits are excessive, you
should replace the spark plug with the
specified plug.

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. @4. Install the spark plug caps.
EAU01765*
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.

Cooling system1. Remove the seat. (See page 3-14
for seat removal and installation
procedures.)
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, add coolant or
distilled water to raise it to the
specified level.
4. Install the seat.

CAUTION:@ Hard water or salt water is harmful
to the engine. You may use soft wa-
ter if you can’t get distilled 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
The radiator fan operation is com-
pletely automatic. It is switched on
or off according to the coolant tem-
perature in the radiator.

and clean it with solvent. After
cleaning, squeeze the air filter to
remove the remaining solvent.7. Apply recommended oil to the en-
tire surface of the filter and
squeeze out the excess oil. The air

Carburetor adjustmentThe carburetors are important parts of
the engine and require very sophisti-

should be left to a Yamaha dealer who
has the professional knowledge and
experience to do so. However, the idle
speed may be adjusted by the owner
as part of routine maintenance.

CAUTION:@ The carburetors were set at the
Yamaha factory after many tests. If
they are changed, poor engine per-
formance and damage may result. @
