2008 YAMAHA TZR50 drain bolt

1. Spark plug wrench
3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
NOTE:
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. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
4. Install the spark plug cap.
5. Install the cowling.EAUM1270
Transmission oil
The transmission oil level should be
checked before each ride. In addition,
the oil must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
To check the transmission oil level
1. Place the vehicle on a level surface
and hold it in an upright position.
NOTE:
Make sure that the vehicle is positio-
ned straight up when checking the oil
level. A slight tilt to the side can result
in a false reading.

2. Remove the oil check bolt, andthen check the oil level.
NOTE:
The oil should be at the brim of the
check hole.
3. If the oil is below the brim of thecheck hole, remove the oil filler
cap, add sufficient oil of the
recommended type to raise it to
the correct level, and then install
the oil filler cap.
4. Install the oil check bolt, and then tighten it to the specified torque.
To change the transmission oil 1. Place an oil pan under the trans- mission oil case to collect the
used oil.
2. Remove the drain bolt and the oil check bolt to drain the oil.
3. Install the drain bolt and the check bolt, and then tighten them
to the specified torque. 4. Remove the oil filler cap, add the
specified amount of the recom-
mended transmission oil, and
then install and tighten the oil
filler cap.

CAUTION:
Make sure that no foreign material
enters the transmission case.
5. Start the engine and let it idle for several minutes while checking
the transmission oil case for oil
leakage. If oil is leaking, imme-
diately turn the engine off and
check for the cause.

The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.

The coolant must be changed at the
intervals specified in the periodic

Have a Yamaha dealer change the
coolant.

NOTE:
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle 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, open thereservoir cap, add coolant to the
maximum level mark, and then
close the reservoir cap.

NOTE:
If the engine overheats, see page
6-33 for further instructions.

To change the coolant
1. Place the vehicle on the centers-
tand and let the engine cool if
necessary.
2. Remove cowlings A and B. (See
page 6-5.)
3. Place a container under the engi-
ne to collect the used coolant.

5. Remove the coolant drain bolt to
drain the cooling system.
6. After the coolant is completely
drained, thoroughly flush the
cooling system with clean tap
water.

NOTE:
Check the washer for damage and
replace it if necessary.
8. Pour the recommended coolant
into the radiator until it is full.
ECA10470
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 coo-
lant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the coo-
ling system will not be protec-
ted 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 possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.
9. Install the radiator cap, start the
engine, let it idle for several minu-
tes, and then turn it off.
10. Remove the radiator cap to
check the coolant level in the
radiator. If necessary, add suffi-
cient coolant until it reaches the
top of the radiator, and then ins-
tall the radiator cap.
11. Check the coolant level in the
reservoir. If necessary, remove
the coolant reservoir cap, add
coolant to the maximum level
mark, and then install the cap.12. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yama-
ha dealer check the cooling sys-
tem.
13. Install the cowlings.
Recommended antifreeze:

freeze containing corrosion inhibi-
tors for aluminum engines

Storage
Short-term
Always store your motorcycle in a
cool, dry place and, if necessary, pro-
tect it against dust with a porous
cover.
ECA10810
CAUTION:
Storing the motorcycle in a
poorly ventilated room or cove-
ring it with a tarp, while it is still
wet, will allow water and humi-
dity to seep in and cause rust.
To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Turn the fuel cock lever to “OFF”.
3. Drain the carburetor float cham-
ber by loosening the drain bolt;
this will prevent fuel depositsfrom building up. Pour the drai-
ned fuel into the fuel tank.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap and
spark plug.
b. Pour a teaspoonful of engine oil
into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit sparking
during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
e. Remove the spark plug cap from
the spark plug, and then install
the spark plug and the spark plug
cap.
