accelerate hard when the engine is
cold!The engine is warm when it quickly
responds to the throttle.

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 distances.
The transmission is properly
lubricated only when the engine
is running. Inadequate
lubrication may damage the
transmission.

Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:l
Shift up swiftly, and avoid high
engine speeds during acceleration.
l
Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.
l
Turn the engine off instead of letting
it idle for an extended length of time
(e.g., in traffic jams, at traffic lights
or at railroad crossings).
EAU16841
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
following 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-throttle
operation or any condition that might
result in engine overheating must be
avoided.
EAU17100
0-1000 km (0-600 mi)
Avoid prolonged operation above 5000
r/min.
1000-1600 km (600-1000 mi)
Avoid prolonged operation above 6000
r/min.
ECA11150
After 1000 km (600 mi) of operation,
the engine oil must be changed, and
the oil filter element replaced.
1600 km (1000 mi) and beyond
The vehicle can now be operated
normally.

PERIODIC MAINTENANCE AND MINOR REPAIR
EAU17240
Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in the
safest and most efficient condition
possible. The most important points of
inspection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING ON
THE WEATHER, TERRAIN,
GEOGRAPHICAL LOCATION, AND
INDIVIDUAL USE, THE
MAINTENANCE INTERVALS MAY
NEED TO BE SHORTENED.
EWA10320
If you are not familiar with
maintenance work, have a Yamaha
dealer do it for you.

Checking the spark plugl
The spark plug is an important
engine component, which is easy
to check. Since heat and deposits
will cause any spark plug to slowly
erode, the spark plug should be
removed and checked in
accordance with the periodic
maintenance and lubrication chart.
In addition, the condition of the
spark plug can reveal the condition
of the engine.
To remove the spark plug 1. Remove cowling. (See page 6-6.)
1. Spark plug cap2. Remove the spark plug cap.
3. Remove the spark plug as shown, with the spark plug wrench included
in the owner’s tool kit.
1. Spark plug wrenchTo check the spark plug1. Check that the porcelain insulator around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the
motorcycle is ridden normally).If the spark plug shows a distinctly
different color, the engine could be
defective. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the motorcycle.2. Check the spark plug for electrodeerosion and excessive carbon or
other deposits, and replace it if
necessary.
