EAU16830
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1,000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU17010
0–500 km (0–300 mi)
Avoid prolonged operation above 1/3
throttle.
500–1,000 km (300–600 mi)
Avoid prolonged operation above 1/2
throttle.
CAUTION:

ECA11150
After 1,000 km (600 mi) of operation,
the engine oil must be changed, and
the oil filter element replaced.
1,000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.
CAUTION:

ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
EAU17200
Parking
When parking, stop the engine, and
then remove the key from the main
switch.
WARNING

EWA10310

Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them.

Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn.

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.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
NOTE:

Make sure that the vehicle is positioned
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
several 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 element replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engineto collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:

Skip steps 4–6 if the oil filter element is

not being replaced.
4. Remove the oil filter element cover
by removing the bolts.
5. Remove and replace the oil filter
element and O-ring.6. Install the oil filter element cover by
installing the bolts, then tightening
them to the specified torque.
NOTE:

Make sure that the O-ring is properly
seated.
7. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
8. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.
CAUTION:

ECA11620

In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not 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.
