deteriorate quickly and unexpectedly- even if it remains unused (for instance, if it is exposed to the elements). Any

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.
