During manufacture only the best possible materials
are used and all machined parts are finished to a
very high standard but it is still necessary to allow
the moving parts to "BREAK-IN" before subjecting
the engine to maximum stresses. The future
performance and reliability of the engine depends
on the care and restraint exercised during its
early life. The general rules are as follows:
BREAK-IN PROCEDURE
Keep to these break-in gine speed limits: en
Upon reaching an odometer reading of 1,600 km
you can subject the motorcycle to full throttle
operation.
However, do not exceed 10,000 r/min at any
time.
Do not maintain constant engine speed for an
extended time period during any portion of the
break-in. Try to vary the throttle position.
