Adjusting the spring tension of
the throttle control
Fig 9:4
Back off screw B about 1-11/2 turns. Grip sleeve C with
a pair of pliers.
Slacken stop screw D and hold the throttle control firmly.
Rotate sleeve C in the direction of the arrow to increase
the spring tension.
Do not adjust by more than a 1/4-turn at a time as the
spring may otherwise be damaged.
Adjust the throttle control cable as above.
If it is not possible to adjust the spring tension it may be
because the spring has Jumped out of position or has
become deformed in such case disconnect the throttle
control cable from the handlebar and remove sleeve C.
Inspect the return spring and fit a replacement if neces-
sary.
Then carry out adjustment as described above.
