During the first 1600 kms. (1000 miles) a
new or overhauled machine should be used
intelligently since the efficiency,
performance,
a.nd life of the engine are largely dependant
on how it is used.
The englne
should never be allowed to reach
a high
number of revolutions before it has
had a chance to sufficiently warm up.
Never ride the machine
at the highest speeds
permitted for each gear before the machine
has been well broken in.
Should the engine speed drop off considerably
on an uphill grade, a lower gear
should be im.
mediately engaged. In case of overheating, it
is best to stop the engine and allow it to cool
down.
Under
no circumstances whatever should the
Following speeds be exceeded while a machine
is being run in.
Maximum permissible speed:
Distance covered:
Up to 800 kms. (500 miles) :
in low gear
in second gear
in third gear
45 (28 miles)
65 (40.5 miles)
85 (53 miles)
in high gear 110 ( 68 miles)
From
800 to 1600 kms. (500 to 1000 miles) :
in low gear 55 (34.5 miles)
in second gear 80 (50 miles)
in third gear IDS (65 miles)
in high gear 135 (84 miles)
From 1600 to
3000 kms. (1000 to 1800
miles) :
Gradually increase the speed up to the ma-
ximum permissible limit.
