RUNNING IN
After the
first 500 kms.
(300 miles)
Every 500 kms.
(300 miles)
During the first 1600 kms. (1000 miles), a
new or overhauled machine ought
to be used
with some intelligence as the efficiency, per-
formance,
and life of the engine are largely
dependant
on how it is run in.
The engine should never be allowed to reach
a high number
of revolutions before it has
had a chance to warm up sufficiently. Never
ride the machine at the highest permissible
speeds
for each gear before the machine has
been well broken in.
Should the engine speed drop
off considera·
bly on an uphill grade, a lower gear should
be immediately engaged. In case of overheat-
ing,
it is best to stop and allow the engine
to cool down.
Under
no circumstances whatever should the
following speeds
be exceeded in the running
in period.
Maximum permissible speeds:
Distance: up to 800 kms. (500 miles):
in low gear. 45 kms. (28 miles)
in second gear
65 kms. (40 miles)
in third gear
85 kms. (53 miles)
in fourth gear
100 kms. (62 miles)
in top gear
115 kms. (72 miles)
from 800 to 1600 kms. (500 to 1000 miles):
in low gear. 55 kms. (34.5 miles)
in second gear .
80 kms. (50 miles)
in third gear. . 105 kms. (65 miles)
in fourth gear .
120 kms (75 miles)
in top gear
.. 140 kms. (87,5 miles)
From
1600 to 3000 kms. (1000 to 1800 miles)
the speed
can be gradually increased up to
the maximum permissible limits.
Change the engine oil.
Tighten all nuts
and bolts.
Check valve clearance.
Check
distributor points.
Chek oil level. Correct level is in between
the minimum and maximum mark
on the
filler cap dipstick.
