GENERAL INFORMAT1ON 1-2
BREAKING-IN PROCEDURES
During manufacture only the best possible materi-
als 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 subject-
ing 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:
Keep to these
b
reakingin engine speed limits:
Upon reaching an odometer reading of 1,600 krn
(1,000 miles) you can subject
the
motorcycle
to
full throttle operation,
However, do not exceed
9,000
rlmin at
any
time.
Do
not
maintain constant engine speed for
an
A
extended time period during any portion of the
break-in. Try to vary the throttle position.
CYLINDER IDEMTI FTCATION
The four cylinders
of
this engine are identified as
Na. 1,
No.
2, No. 3 and No. 4 cylinder, ascounted
from left to right (as viewed by the rider on the
seat).
SPECIAL FEATURES
BLOWBY GAS RECYCLING
Blowby gases in the crankcase are constantly
drawn into the chain chamber provided in the
middle section
of
the cylinder block. The top
section of this chamber is cannmed with the air
chamber assembly through
a
rubber tube. In the
air chamber, the gases merge with incoming air and
thus are
recycled to the engine through the normal
intake system.
