6.4. 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.
