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 build up 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.
