Throttle Requirements
NOTE: S&S Super E & G carburetors require the use of a two cable, pull open - pull closed throttle assembly. All models equipped with a single cable throttle
mechanism must be converted to the two cable, pull open - pull closed type. S&S offers a variety of these throttle assemblies.
Single, braided wire cable throttle mechanisms cannot mechanically close the throttle. If the throttle inadvertently sticks in the open
position, loss of control of motorcycle and personal injury to you or others may result.
Any motorcycle equipped with single cable throttle system must be converted to a two cable system. Kits with 36" (91cm), 39" (99cm), 42" (107cm),
48" (122cm), or 52" (132cm) length cables are available. Throttle assembly kits may be ordered separately. See descriptions below.
Two cable throttle systems designed for a butterfly type carburetor have cable fittings that can simply be “plugged in” to the S&S Super E or G
carburetor throttle linkage.
Optional S&S Two Cable Throttle Kits
Kits fit 1” (25.4mm) O.D. handlebars and can be used on most chassis. An adapter sleeve is available for use with handlebars having 7/8” (22.2mm)
ends. Fittings on provided cables readily “plug in” to S&S® Super E, G, or stock H-D 1981 and later butterfly type carburetors. Kits include one opening
side cable, one closing side cable, left and right handlebar grips, and handlebar clamps.

NOTE: 1981 to 1990 OEM style cables may be used as replacement cables for throttle kits above.
5- Throttle/Cables
A- Install new throttle assembly.
I- Install new throttle assembly and cables. Position grip and cables so cables can be angled towards carb for easy adjustment and free
operation.
II- Apply light coat of clean cable lubricant to cables and fittings. Loosen cable adjustment locknuts and turn adjusting screw so half of
the threads are exposed.
6- Throttle/Cable Assembly
A- Install throttle cables on carburetor.
I- Remove throttle cable housing bracket, PN 11-2339.
II- Install opening side throttle cable barrel fitting and throttle cable in throttle linkage on appropriate side of throttle cable housing
bracket. Opening side cable housing outside diameter is smaller and measures .190” (4.826mm).
III- Repeat step II for closing side throttle cable. Closing side cable has a spring around inner cable wire.
IV- Reinstall throttle cable housing bracket on carburetor.
B- Turn throttle cable adjusters to remove excessive free play. Test the throttle to ensure it opens and closes freely. The throttle should snap
shut when released. Turn handlebars to extreme left and open and close throttle, then turn bars to extreme right and repeat. If throttle
binds, loosen cable adjusters to put more free play in cables. Tighten the adjusting screw locknuts after final adjustments are made.
NOTE: Throttle grip assembly must be assembled correctly and work freely to prevent possible sticking during operation. Cable routing must be free of
tight bends to minimize cable to cable housing friction. Throttle must not bind and must snap shut to fully closed position when released.
Incorrect cable adjustment may cause throttle to stick open, causing loss of control of motorcycle, serious injury or death.
