6.5. ENGINE BREAK-IN
There is never a more important period in the life of
your machine than the period between zero and 20
hours.
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
20 hours; 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
engine heating must be avoided.
However, momentary (2~3 seconds maximum) full
throttle operation under load does not harm the
engine.
Each full throttle acceleration sequence should be
followed with a substantial rest period for the engine
by cruising at lower r/min so the engine can rid itself
of the temporary buildup of heat.
If any abnormality is noticed during this period,
consult a KYMCO dealer.
1. 0~10 hours:
Avoid continuous operation above half
throttle. Allow a cooling off period of five to
ten minutes after every hour of operation.
Vary the speed of the machine from time to
time. Do not operate it at full throttle position.
2. 10~20 hours:
Avoid prolonged operation above 3/4 throttle.
Rev the machine freely through the gears but
do not use full throttle at any time.
3. After break-in:
Avoid prolonged full throttle operation. Vary
speeds occasionally.
