Checking the spark plugs The spark plugs are important engine
components, which are easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plugs 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.
To remove a spark plug
1. Remove the spark plug cap.2. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.To check the spark plugs
1. Check that the porcelain insulator
around the center electrode on
each spark plug is a medi-
um-to-light tan (the ideal color
when the motorcycle is ridden nor-
mally).
2. Check that all spark plugs installed
in the engine have the same color.
NOTE:_ 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. _

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. Start the engine, warm it up for sev-
eral minutes, and then turn it off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-right side of the
crankcase.NOTE:_ The engine oil should be between the
minimum and maximum level marks. _4. 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.To change the engine oil (with or
without oil filter cartridge replace-
ment)
1. Remove cowling A. (See page 6-5
for cowling removal and installa-
tion procedures.)
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Place an oil pan under the engine
to collect the used oil.1. Engine oil level check window

then tighten it to the specified
torque.
9. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.
ECA00105
CAUTION:_

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 grade “CD”
or higher. In addition, do not
use oils labeled “ENERGY CON-
SERVING II” or higher.


Make sure that no foreign mate-
rial enters the crankcase.
_
10. 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.NOTE:_ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. _
EC000067
CAUTION:_ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. _11. Turn the engine off, and then
check the oil level and correct it if
necessary.
12. Install the cowling. Tightening torque:
Engine oil drain bolt:

Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_

The coolant level must be checked
on a cold engine since the level
varies with engine temperature.


Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.
_
2. Check the coolant level in the
coolant reservoir.NOTE:_ The coolant should be between the
minimum and maximum level marks. _3. If the coolant is at or below the
minimum level mark, remove the
seat (See page 3-11 for seat re-
moval and installation proce-
dures.), and then open the coolant
reservoir cap.
4. Add coolant or distilled water to
raise the coolant to the specified
level, close the coolant reservoir
cap, and then install the seat.
EC000080
CAUTION:_

If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.


If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.


If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.

stalling the bolts.
16. Pour the specified amount of rec-
ommended coolant into the radia-
tor and reservoir.
ECA00041
CAUTION:_ Hard water or salt water is harmful
to the engine. You may use soft wa-
ter if you can’t get distilled water. _17. Install the radiator cap and the
coolant reservoir cap, start the en-
gine, let it idle for several minutes,
and then turn it off.
18. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap.
19. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
20. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
21. Install the right air intake duct, and
then tighten the clamp screws.22. Place the fuel tank in the original
position, and then install the bolts.
23. Install the cowlings.

to the entire surface of the sponge
material, and then squeeze the ex-
cess oil out.
NOTE:_ The air filter element should be wet but
not dripping. _8. Insert the air filter element into the
air filter case.
EC000082*
CAUTION:_

Make sure that the air filter ele-
ment is properly seated in the
air filter case.


The engine should never be op-
erated without the air filter ele-
ment installed, otherwise the
pistons and/or cylinders may
become excessively worn.
_9. Install the air filter case cover by
installing the screws.
10. Place the fuel tank in the original
position, and then install the bolts.
EW000072
WARNING
_

Before installing the fuel tank,
make sure that the fuel hoses
are not damaged. If any fuel
hose is damaged, do not start
the engine but have a Yamaha
dealer replace the hose, other-
wise fuel may leak.


Make sure that the fuel hoses
are properly connected and
routed, and not pinched.
_11. Install the seat.
EAU00626
Checking the air vent hose Periodically check the air vent hose for
dust or water that may be deposited in
the hose. If dust or water is found, re-
move the air vent hose, thoroughly
clean it, and then install it.
EC000093
CAUTION:_ Do not operate the motorcycle with
the air vent hose removed. _

Air intake duct Check that the screen of the intake

necessary.
EAU00630
Adjusting the carburetors The carburetors are important parts of
the engine and require very sophisti-
cated adjustment. Therefore, most car-
buretor adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience. The adjustment described in
the following section, however, may be
serviced by the owner as part of routine
maintenance.
EC000095
CAUTION:_ The carburetors have been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine. _
EAU00632
Adjusting the engine idling
speed The engine idling speed must be
checked and, if necessary, adjusted as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine and warm it up for
several minutes at 1,000–
2,000 r/min while occasionally rev-
ving it to 4,000–5,000 r/min.NOTE:_ The engine is warm when it quickly re-
sponds to the throttle. _
