Description of camshaft
The camshaft of this engine has a cam sprocket
at the center and polished cam sections at the right
and left sides. The bearing sections are a logical
type which. are supported by the side cover and point
base.
The cam sprocket is driven by the cam chain from
the gear shift at
1
/2 transmission gear ratio.
(Refer
to Fig. 25)
The cam provides a damping curve over a fairly
large range between the base circle and the cam
unit, and damps the shock generated when the rocker
hits the lift curve ; this prevents noise.
(Refer to Fig.
