OPERATION AND IMPORTANT RIDING POINTS
Tips for reducing fuel
consumptionYour Motorcycle's fuel consumption
depends to a large extent on your
riding style. The following tips can
help reduce fuel consumption:
1. Warm up the engine before riding.
2. Move the strater Lever to “Off” as
soon as possible.
3. Shift up swiftly and avoid high
engine speeds during
acceleration.
4. Do not double-clutch or rev the
engine while shifting down and
avoid high engine speeds with no
load on the engine.
5. Turn off the engine instead of
letting it idle for an extended
length of time, i.e. in traffic jams, at
traffic lights or rail- road crossings.
6. Do not drive with excessive load
on the Motorcycle.
7. Plan your route in advance.
Running-inThere is never a more important
period in the life of your Motorcycle
than the period between zero and
1,000 kms. For this reason we ask
that you carefully read the following
material. Because the engine is brand
new, you must not put an excessive
load on it for the first 1,000 kms. 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 which
might result in excessive heating of
the engine, must be avoided.Be sure to replace the engine
oil as per recommended
schedule.
1,000 kms and below :
Avoid prolonged full-throttle
operation. Vary speed
occasionally.
5-3
CAUTION :
8. Avoid frequent braking.
9. Always maintain your tyre
pressure as per recommendation
10. Get your motorcycle serviced
periodically after every 2000 kms.
If any engine trouble should occur
during the "Running-in" period,
consult a YAMAHA dealer
immediately.

power.
Clean Element Air Cleaner after

The Element Air Cleaner should
be cleaned and lubricated more
frequently (every 1000 kms), if
Motorcycle is operated in very
dusty (e.g. unpaved, dust laden
roads) conditions.
Carburetor adjustmentThe carburetor is a vital part of the
engine and requires very sophisti-
cated adjustments. Most adjust-
ments should be left to a YAMAHA
dealer who has the professional
knowledge and experience to do so.
However, the following may be
serviced by the owner as part of
routine maintenance.
The carburetor is set at the
YAMAHA factory after many
tests. If the settings are changed,
poor engine performance and
damage may result.

WARNING1. It is dangerous to ride with a
worn-out tyre. When a tyre
tread begins to show lines,
have a YAMAHA dealer replace
the tyre immediately.
WheelsTo ensure maximum performance,
long service, and safe operation,
note the following:
1. Always inspect the wheels before
a ride. Check for cracks, bends or
warpage of the wheel. Be sure the
spokes are tight and undamaged.
If any abnormal condition exists in
a wheel, consult a YAMAHA
dealer. Do not attempt even small
repairs to the wheel. If a wheel is
deformed or cracked, it must be
replaced.
2. Tyres and wheels should be
balanced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse
handling characteristics, and
shortened tyre life.3. Ride at moderate speeds after
changing a tyre since the tyre
surface must first be broken in for
it to develop its optimal
characteristics.PERIODIC MAINTENANCE AND MINOR REPAIR
