Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1,000 km. For this rea-
son, you should read the following ma-
terial carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,000 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full-throttle oper-
ation or any condition that might result
in engine overheating must be avoided.
