RUNNING IN
During the first 1600 kms. 11,000 miles). a new or overhauled machine ought to be used
with some intelligence as the efficiency, performance, end life of the engine are largely
dependent on how it is run in.
The engine should never be allowed to reach 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 considerably on an uphill grade, a lower gear should be
immediately engaged. In case of overheating, 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. (40.5 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 1400 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.
After the first 500 kms. (300 miles)
Change the engine oil.
Tighten all nuts and bolts.
Check valve clearance.
Check distributor points.
Every 500 kms. (300 miles)
