Removing and installing
cowlings and panels
The cowlings and panels shown need
to be removed to perform some of the
maintenance jobs described in this
chapter. Refer to this section each time
a cowling or panel needs to be re-
moved and installed.
EAU18991
Cowlings A and B
To remove one of the cowlings
Remove the cowling screws and the
quick fastener, and then pull the cowl-
ing off as shown.
TIP

To install the cowling
Place the cowling in the original posi-
tion, and then install the screws and the
quick fastener.TIP

To install the quick fastener, push the
center pin out so that it will protrude
from the fastener head, insert the fas-
tener into the cowling, and then push
the protruding pin in until it is flush with
the fastener head.

Panels A and B
To remove one of the panels
1. Remove the corresponding cowl-
ing A or B. (See page 6-7.)
2. Remove the seat. (See
page 3-16.)
3. Remove the screw, and then take
the panel off.To install the panel
1. Place the panel in the original po-
sition, and then install the screw.
2. Install the seat and the cowling.

EAU19642
Checking the spark plugs
The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they 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.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.

Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
TIP

If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible.
EAU19836
Engine oil and oil filter
element
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart. A slight tilt to the side can
result in a false reading.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
2. Start the engine, warm it up for 15
minutes, and then turn it off.
3. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in and with the arrow
mark pointing upward as shown),
and then remove it again to check
the oil level.
WARNING! Never re-
move the engine oil tank cap af-
ter high-speed operation,
otherwise hot engine oil could

[EWA10361]
NOTICE:
Do not operate the ve-
hicle until you know that the en-
gine oil level is sufficient.
[ECA10011]

TIP

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.
5. Install the oil filler cap.
TIP


The engine oil tank is located be-
hind the cylinders.

The engine oil should be between
the minimum and maximum level
marks.
To change the engine oil (with or
without oil filter element replace-
ment)
1. Place the vehicle on a level sur-
face.
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.
4. Remove the engine oil filler cap,
the engine oil drain bolts and their
gasket to drain the oil from the
crankcase.

TIP

Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
NOTICE

ECA11620

In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Donot use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING 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, im-
mediately turn the engine off and
check for the cause.
11. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU20070
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.
EAU38583
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
TIP


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

Make sure that the vehicle is posi-
tioned 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 cool-
ant reservoir.
TIP

The coolant should be between the
minimum and maximum level marks.

Engine oil drain bolt A:
35 Nm (3.5 m·kgf, 25 ft·lbf)

3. If the coolant is at or below the
minimum level mark, remove pan-
el B for TDM900 or panel A for
TDM900A (See page 6-7.), re-
move the reservoir cap, add cool-
ant to the maximum level mark,
and then install the reservoir cap
and the panel.
WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.

[EWA15161]

NOTICE:
If
coolant is not available, use dis-
tilled water or soft tap water in-
stead. 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 coolant as soon as possi-
ble, otherwise the cooling sys-
tem will not be protected against
frost and corrosion. If water has
been added to the coolant, have
a Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.

Replacing the air filter element
The air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the seat. (See
page 3-16.)
2. Remove cowlings A and B as well
as panels A and B. (See
page 6-7.)
3. Remove the fuel tank bolts.
TIP

For TDM900, skip steps 4 and 12.
4. Remove the rear brake fluid reser-
voir holder by removing the bolt.
For TDM900A
5. Lift the fuel tank away from the air
filter case, but do not disconnect
the fuel hoses.
WARNING! Make
sure that the fuel tank is well
supported. Do not tilt or pull the
fuel tank too much, otherwise
the fuel hoses may come loose,
which could cause fuel leakage
and a fire hazard.

7. Pull the air filter element out.
8. Insert a new air filter element into
the air filter case.
NOTICE:
Make
sure that the air filter element is
properly seated in the air filtercase. The engine should never
be operated without the air filter
element installed, otherwise the
piston(s) and/or cylinder(s) may
become excessively worn.

[ECA10481]

9. Install the air filter case cover by in-
stalling the screws.
10. Place the fuel tank in its original
position. Make sure that the fuel
hoses are properly connected and
routed, and are not pinched. Be
sure to place the fuel tank breather
hose and the overflow hose in their
original position.
WARNING! Be-
fore 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, creating a
fire hazard.

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.
The engine should be warm before
making this adjustment.
Check the engine idling speed and, if
necessary, adjust it to specification by
turning the idle adjusting screw. To in-
crease the engine idling speed, turn the
screw in direction (a). To decrease the
engine idling speed, turn the screw in
direction (b).
TIP

If the specified idling speed cannot be
obtained as described above, have a
Yamaha dealer make the adjustment.
