Engine break-in
WARNING
EWA10321
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer performservice.1. Before starting the engine, fill the fuel tank with the fuel.
2. Start and warm up the engine. Check the operation of the controls
and the engine stop switch. (See
page 3-7.) Then, restart the engine
and check its operation within no
more than 5 minutes after it is re-
started.
3. Operate the motorcycle in the low- er gears at moderate throttle open-
ings for five to eight minutes. Stop
the engine.
4. Check how the engine runs when the motorcycle is ridden with the
throttle 1/4 to 1/2 open (low to me-
dium speed) for about one hour. 5. Start the engine and check the op-
eration of the motorcycle through-
out its entire operating range.
Restart the motorcycle and ride it
for about 10 to 15 more minutes.
The motorcycle will now be ready
to ride normally.
After the engine break-in period, thor-
oughly check the motorcycle for loose
parts, oil leakage and any other prob-
lems. Be sure to inspect and make ad-
justments thoroughly, especially cable
and drive chain slack and loose
spokes. In addition, check all fittings
and fasteners for looseness, and tight-
en if necessary.
NOTICE
ECA15560

When any of the following parts
have been replaced, they must
be broken in.
Cylinder or crankshaft:
About one hour of break-in op-
eration is necessary.
Piston, rings or transmission
gears:
These parts require about 30
minutes of break-in operation at
half-throttle or less. Observe the condition of the engine carefully
during operation.

If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-cle.

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.
TIPIf 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.

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 several minutes, and then turn it
off.
3. Wait a few minutes until the oil set- tles, remove the oil tank cap, wipe
the dipstick clean, insert it back
into the oil tank (without screwing it
in), and then remove it again to
check the oil level. WARNING!
Never remove the engine oil
tank cap after high-speed oper-
ation, otherwise hot engine oil
could spout out and cause dam-
age or injury. And do not touch
