Control must operate freely and carburetor throttle must return to closed (idle) position with friction adjusting screw (12, Figure 2-31) backed off. If control becomes stiff and does not return properly, it should be disassembled, cleaned and inspected.


Remove two control coil clamp screws (1), upper clamp (2), lower clamp (3). Unhook ferrule end of control wire (9) from grip assembly (4) which is free to come off handlebar end (17).

To remove cable (9), disconnect it at carburetor throttle lever, unsolder or cut off ferrule (16) and pull wire out ol lower clamp (3). Parts 5, 6, 7, 8 and 10 are now removable. Replace a worn or bent control wire with a new one through parts 5, 6, 7 and 8 and install in casing (10) applying graphite grease to wire. Solder ferrule on wire flush with end of wire.

Apply a light coat of graphite grease to handlebar (17) end and inside surfaces of clamps (2 and 3).

Connect ferrule end of wire to notch in drum and assemble grip (4) on handlebar between clamps. Be sure hole in friction spring (13) is in place on end of screw (12).

After assembling parts and connecting wire end to throttle lever, check for proper operation - that is, with friction screw (12) loosened, torsion spring on carburetor throttle shaft must return parts to closed throttle (idle) position.

With handgrip turned to throttle fully opened position, adjust stop screw (11) using 2 MM hex (Allen) wrench to limit travel. Important! This should be done to prevent excessive pull, and possible wire ferrule breakage
