HANDLEBAR THROTTLE CONTROL
GENERAL

Control must operate freely and carburetor throttle must return to closed (idle) position with friction adjusting screw (10, figure 2-22) backed off. If control becomes stiff and does not return properly, it should be disassembled, cleaned and inspected.
DISASSEMBLING THROTTLE CONTROL (Figure 2-22)

To disassemble and inspect throttle control assembly, remove the two screws (1) holding the upper throttle clamps (2) to the lower throttle clamp (3). Unhook ferrule (4) from ball on end of cable (5) and from throttle grip (6). Disconnect opposite end of cable from carburetor.

Turn out the hex fitting securing the cable (5) to the lower clamp (3) and remove cable assembly from motorcycle.

Remove the friction spring (7), set screw (8), spring (9) and adjusting screw (10) from lower clamp.
INSPECTION AND CLEANING

Clean all metal parts in non-flammable cleaning solvent. Blow dry with compressed air. Replace any broken, cracked, or worn parts. Replace cable assembly if it is frayed, kinked, or bent.
ASSEMBLING THROTTLE CONTROL

After inspection, position cable assembly (5) on motorcycle. Apply a light coat of graphite to handlebar (11) and inside surface of clamps (2 and 3). Attach lower throttle clamp (3) to cable assembly. Insert set screw (8). adjusting screw (10) and spring (9) in lower clamp. Place friction spring (7) in clamp. Be sure hole in spring (7) engages adjusting screw (10).

Place ridge of throttle (6). positioned on handlebar, into groove of lower throttle clamp (3). Position ferrule (4) over ball of cable (5) and seat in throttle notch. Secure with upper clamp (2) and two screws (1). Tighten screws (1) to 12 to 16 in-lbs torque.
ADJUSTMENT

1. When turned by hand and then released, the throttle lever must return throttle grip (6) to the closed or idle position. If throttle grip (6) does not return to idle position freely, back off of adjusting screw (10) until this is accomplished. If the throttle grip turns stiffly, it should be disassembled, cleaned and inspected thoroughly.
