On current backplates, the pivot point for the enrichener does
not have a screw holding it; a boss has been cast onto the
backplate to replace this.
3- Throttle Preparation
NOTE: Throttle grip assembly must be assembled correctly and work
freely to prevent possible sticking during operation. Throttle must
snap closed when released. Cable routing must be free of tight bends
to minimize friction between cable and housing.
If throttle does not work freely, it may inadvertently stick
open possibly causing loss of control of motorcycle and
personal injury to operator or others.
A- Install new throttle assembly - Motorcycles not equipped
with two cable pull open-pull closed type throttle
assembly.
1- Remove existing throttle cables and throttle grip
assembly. Note routing of stock cables.
2- Install new throttle assembly and throttle cables.
Position grip and cables so cables can be angled back
toward carb for easy adjustment and free operation.
3- Apply light coat of cable lubricant to cables/fittings.
4- Loosen cable free play adjustment locknuts and
thread adjusting screw so half of threads are
exposed. See Picture 6.

B- Prepare existing throttle assembly - 1981-1985 Harley-
Davidson® Sportster® and 1981-1984 big twin chassis
equipped with two cable pull open-pull closed type
throttle assembly.
1- Loosen cable free play adjustment locknuts and
thread adjusting screw so half of threads are
exposed. See Picture 6.
2- Clean grease and dirt off cables, cable housings and
cable fittings.
3- Apply light coat of cable lubricant to cables and
fittings.
4- Install New Manifold and Mounting Hardware
NOTE: When applicable, all carburetor mounting brackets and
hardware supplied in kit must be installed to secure carburetor and
air cleaner backplate assembly or air horn rigidly to engine.
Improperly mounted carburetor could loosen unexpectedly,
resulting in air leak, poor performance and possible damage
to engine or carburetor.
Incorrect combinations of mounting hardware may cause
mounting bolts to bottom out in holes or inadvertently
contact other parts possibly causing damage to engine or
carburetor components.
Improperly mounted carburetor may break free in event of
collision or other vehicle accident creating a fire hazard with
potential personal injury to operator/others.
A- All models: Clean intake ports on cylinder heads to insure
proper manifold to head seal.
NOTE: Cylinder heads for knucklehead engines 1936-'47 and
panhead engines 1948-'54 must be converted to o-ring style
manifold and seals. Conversion kits are available from S&S®. See the
Vintage section of the S&S Catalog.
B- All models: Install S&S® intake manifold. If applicable,
vacuum advance fitting must point upward. Do not
completely tighten manifold clamps.
