Handlebar throttle control must operate freely. If a control becomes stiff and hard to adjust, parts must be removed and cleaned of caked grease, gum and dirt. A kinked control wire or cap must be replaced.


1. Disconnect control coil and wire at carburetor.

2. Insert a large screwdriver through hole in end of grip (Figure 2-28) and loosen handlebar end screw (1). Handlebar end screw and spring (2) will remain inside grip. Remove grip sleeve assembly (3), exposing working parts.

Figure 2-29. Removing Handlebar Control (Spiral Type)

3. Slip two rollers (5) off roller pin (4) and remove roller pin from plunger (6). Plunger with control wire (8) may be pulled through handlebar. If the control wire is broken, remove lower end at carburetor or circuit breaker. The control wire is fastened into the end of the plunger by means of set screw (7).

4. If control coil is to be removed, loosen the lock screw under the horn or starter button retainer on the handlebar that positions the coil end plug (9) in handlebar. The throttle end plug lock screw is exposed on the underside of the right handlebar. After loosening, control coils and end plugs may be pulled out of handlebar ends.
