Engine break-in

There is never a more important pe-
riod in the life of your engine than
the period between 0 and 1,000 km
(600 mi). For this reason, you should
read the following material carefully.

Since the engine is brand new, do
not put an excessive load on it for
the first 1,000 km (600 mi). The vari-
ous parts in the engine wear and
polish themselves to the correct op-
erating clearances. During this pe-
riod, prolonged full-throttle opera-
tion or any condition that might re-
sult in engine overheating must be
avoided.
