7.2 Shift Mechanism C.D.I.
The C.D.I. is located underneath the front hood cover. It includes the
shift control system. Replace it if the control system is functioning
improperly. There is also a speed-limit adjuster in the corner.
Adjust speed-limited as follows:
Sensor
Inspect wire for break or damage and check the contact. Measure sensor dimension (fig-1) after removing the
sensor.
If the length of the sensor is below 30mm (1.18 in), it must be
replaced.
SERVICE LIMITS: 30 mm (1.18 in)
7.3 Automatic Variable Speed Transmission (C.V.T.)
This transmission is a combination of an automatic centrifugal clutch
and V-belt continuous variable transmission, which changes the
transmission ratio automatically.
When engine speed increases, the drive pulley will push the belt by
centrifugal force from six rollers. This causes the pitch circle of the
belt in the drive pulley to increase. The belt at the driven pulley is
forced to move to the center of the shaft, causing the radius of the
pitch circle to decrease.
The transmission ratio is therefore altered by the alteration of the
pitch circle’s radius.
(NOTE: In the drawing, “H” means high speed; “L” means low
speed.)
