●
Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
●
Always use the clutch while
changing gears to avoid damag-
ing the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:●
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
●
Do not rev the engine while shifting
down, and 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 traffic
lights or at railroad crossings).
EAU16841
Engine break-in There 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 follow-
ing 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.
EAU17113
0–1000 km (0–600 mi)
Avoid prolonged operation above 2500
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil and
transfer case oil must be changed,
and the oil filter cartridge or element
replaced.
[ECA10892]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 3500
r/min.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE
ECA10310
●
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.

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.
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.
Specified spark plug:
NGK/DPR8EA-9
DENSO/X24EPR-U91. Spark plug gapSpark plug gap:0.8–0.9 mm (0.031–0.035 in)
Tightening torque:

Engine oil and oil filter car-
tridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Remove the rider seat. (See page 3-16.)
3. Start the engine, warm it up until the engine oil has reached a nor-
mal temperature of 60 °C (140 °F),
let it continue to idle for ten sec-
onds, and then turn the engine off.TIPTo achieve the proper engine oil tem-
perature for an accurate oil level read-
ing, the engine must have first completely cooled down, and then
warmed up again for several minutes to
normal operating temperature.
4. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the engine oil dipstick clean, insert
it back into the oil filler hole (with-
out screwing it in), and then re-
move it again to check the oil level.TIPThe engine oil should be between the
minimum and maximum level marks.
5. If the engine oil is at or below theminimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.TIPWhen adding oil, be careful not to over-
fill the engine oil tank; the oil level rises
faster starting from the half level portion
on the dipstick.6. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
7. Install the rider seat.

of recommended engine oil
through the filler hole, insert the
dipstick, and then ti ghten the oil fill-
er cap.
13. Start the engine, rev it several times, and then turn it off.
14. Remove the engine oil filler cap, and then gradually fill the oil tank
with the remaining oil quantity
while regularly checking the oil lev-
el on the dipstick.
TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
