Inspection should be performed
with
sufficient
attention because wrong lubrication decreases per-
formance of the engine, and causes seizure, noise
and other trouble.
B. Operation of oil filter
In CB 125 and 160, trouble concerning the engine
oil is prevented by double filtering, wire mesh and
filter.
(Refer to Fig. 3. 73)
Before being sucked up by the pump, oil is filtered
by the filter screen and oil impurities are eliminated
by separation filtering using centrifugal force.
This oil filter at the same time collects oil impuri-
ties at the ribs of the oil filter cap by gravity, gives
collective flow to oil, and supplies clean oil to each
unit.
