Carburetor Connections

A connection to the throttle linkage on the carburetor is needed for the servo actuator cable to

pull upon. This may be done with a "bellcrank", which is an extension arm attached to the

throttle. The cruise control installation manual says to "match the actuator pull to throttle travel,

so to be greater than 40 mm, but less than 45 mm, to avoid a condition where the actuator is

pulling past the full throttle stop and introducing the possibility of damaging the linkage."

Alternative 1: Downward Bellcrank For Forward Pulling Actuator

Advantages Disadvantages

• Short design is less susceptible to

bending

•

Full 50º rotation of throttle pulley

•

Provides less than the recommended

40-45 mm throw of CC actuator cable

•

Short throw requires the use of a higher

vacuum sensitivity setting, which may

result in sharp throttle responses that

could jerk the rider.

•

Actuator must pull harder to achieve

the same throttle rotation as a longer

bellcrank

•

Potential for actuator cable or bead

chain rubbing or snagging on engine

shroud

To accommodate the forward-pulling actuator, a bellcrank attached to the throttle must extend

downward. Because of the limited space created by the engine shroud, the bellcrank cannot be

much more than 1" to 1-1/2" inches long. Full rotation of the throttle is about 50º, so a 1" (25

mm) bellcrank will have a throw of about 22 mm. Thus, full rotation of the throttle can be

achieved, but only with about half the throw recommended for the CC actuator.

Reshape the "throttle mounting bracket (#28)" in the

CCS100 kit. Cut it to length with a saw and rough

shape with a bench grinder or file. Drill the mounting

hole larger, and then shape with a small flat file to fit

the flattened shaft for the throttle pulley. Use a round

"rattail" file to make indentations to fit the

projections on the throttle pulley. This makes for a

very secure linkage by having the bellcrank closely

fit around the throttle pulley's projections.
