OPERATION AND IMPORTANT RIDING POINTS

EAU16821
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
Avoid high engine speeds with no
load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16842
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 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.
EAU34322
0–1000 km (0–600 mi)
Avoid prolonged operation above 4000
r/min. NOTICE: After 1000 km (600
mi) of operation, be sure to replace
the engine oil, final transmission oil
and the oil filter element.
[ECA12932]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 6000
r/min.1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10311
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

TIPEngine air filters and V-belt air filter
• This model’s engine air filters are equipped with disposable oil-coated paper elements, which must not be cleaned
with compressed air to avoid damaging them.
• The engine air filter elements need to be replaced and the V-belt air filter element needs to be serviced more fre-
quently when riding in unusually wet or dusty areas.21*Cooling system• Check coolant level and vehicle
for coolant leakage.√√√√√

Engine oil and oil filter ele-
mentThe 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 and when the oil change
indicator comes on.
To check the engine oil level
1. Place the vehicle on the center-
stand. 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, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.TIPThe engine oil should be between the
tip of the dipstick and the maximum
level mark.
4. If the engine oil is not between the
tip of the dipstick and the maxi-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil (with or
without oil filter element replace-
ment)
1. Place the vehicle on the center-
stand.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 bolt and its
gasket to drain the oil from the
crankcase.
TIPSkip steps 5…7 if the oil filter element is
not being replaced.5. Remove the oil filter element cover
by removing the bolts. NOTICE:

ment cover, the compression

6 spring will fall out. Take care not
to lose the compression spring.
[ECA12912]
6. Remove and replace the oil filter
element and O-rings.7. Install the compression spring and
oil filter element cover by installing
the bolts, then tightening them to
the specified torque.
TIPMake sure that the O-rings are properly
seated.8. Install the engine oil drain bolt and
its new gasket, and then tighten
the bolt to the specified torque.9. Refill with the specified amount of
the recommended engine oil, and
then install and tighten the oil filler
cap.
TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.NOTICE
