BREAKING IN
|
|
|
|
In the process of manufacture 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 "bed 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.
|
|
|
|
For the first 500 miles throttle openings should
be limited to about one-third of twist grip
movement and the cruising speed should be varied as
much as possible within this limit. Provided the
engine is not allowed to labour, the actual road
speed is relatively unimportant, but throttle
control should be smooth and the gearbox used to
the full to enable the engine to cope with the
prevailing conditions without undue stress. This
will all times avoid violent acceleration.
|
|
|
|
After the 500 miles service the amount of
throttle opening can be increased progressively but
the cruising speed should still be varied. Full
throttle should not be used until the machine has
covered at least 1,000 miles and even then only for
short bursts until 1,500 miles has been covered,
whereupon maximum performance may be sought
whenever desired.
|
|
|
|
During the "break-in" period, a certain amount
of adjustment will be necessary as the components
bed in. Attention should be given to valve rocker
adjustment, chain tension, contact breaker points
gap and brakes, all of which tend to settle down.
|
|
|
|
Do not allow the oil tank level to fall too low,
as with the reduced amount in circulation the oil
will become unduly hot.
|
|
|
|
On motorcycles equipped with the disc brake, it
is most essential to avoid glazing of the friction
surfaces during the first few miles of use. During
the first 50 miles only it is necessary to apply
the disc brake gently to mate the friction
surfaces. After 50 miles of use, the brake will be
fully bedded down and ready for maximum
application.

This section tables the maintenance periods for
various operations, co-relates these operations to
other sections of this manual and details those
operations not falling within the normal scope of
the overhaul sections.
