INTRODUCTION
S&S® Super E Shorty carburetors are designed for big twin and Harley-Davidson® Sportster® models as well as other American v-twin engines. They
are butterfly type carburetors with an accelerator pump for improved throttle responses and a variable enrichment/fast idle device for improved
engine starting and warm ups.
The Super E has a 17⁄8" (47.6mm) bore and 19⁄16" (39.6mm) venturi. It is identified by an "E" cast into the throttle linkage side of the body below the
letters "S&S SUPER".
Picture 1
NOTE: S&S carburetors are jetted at the factory to meet noise and exhaust emissions when properly installed. It is illegal to run the bike without the noise
reducers installed. Operating the motorcycle without the noise reducers will also cause engine damage. The user shall determine the suitability of the
product for his or her use and shall assume all risk and liability in connection therewith.
Kit Contents:
Each complete carburetor kit includes:
One S&S Super E gas carburetor
One S&S teardrop air cleaner assembly with noise reducer
One manifold with noise restrictor
Mounting hardware
Fuel line, fuel line insulator, clamps and overflow line
VOES tubing and additional hardware (when applicable)

CHROME PLATING THE CARBURETOR
NOTE: S&S does not recommend chrome plating the Super E carburetor. Preparation requires polishing with abrasive buffing compounds. These materials
invariably plug air and/or fuel passages and other orifices regardless of precautions taken.
CAUTION
The chrome plating process can alter critical operating tolerances in several areas. Additionally, chrome may obstruct fuel passages,
possibly altering the fuel mixture and causing engine damage. All manufacturer warranties become void if any part of the carburetor is
polished, chrome plated or otherwise altered.
THROTTLE REQUIREMENTS
NOTE: S&S Super E and G carburetors require the use of a two cable, pull open - pull closed throttle assembly. All 1980 and earlier stock H-D® models
equipped with a single cable throttle mechanism must be converted to the two cable, pull open-pull closed type. S&S offers these throttle assemblies but
does not include them with any carburetor kit because of the multitude of chassis designs and fitment requirements.
WARNING
WARNING -Single, braided wire cable throttle mechanisms cannot mechanically close the throttle. If throttle inadvertently sticks in open
position, loss of control of motorcycle and personal injury to operator or others may result.

1981 to Present Big Twin Models
Stock big twin models from 1981 to 1989 have two cable throttle system designed for stock, butterfly type carburetors. Big twins from 1990 to
present have a two cable throttle system designed for the stock, constant velocity (CV) type carburetor. In spite of the differences in throttle cables
for these year groups, stock throttle cables on all 1981 to present big twin models can be installed on the S&S Super E throttle linkage with no cable
modification. S&S® Super E carburetor kits for 1936 to 1989 big twins contain a throttle cable guide designed for butterfly type throttle cables, and
kits for 1990 and later big twins contain a taller throttle cable guide designed for CV type throttle cables. See Picture 2. The two throttle cable guides
are interchangeable on the carburetor body, and can be changed very easily to update older carburetors or to accommodate custom throttle cables
which are not stock for a particular year chassis.
Picture 2
1981 to Present Harley-Davidson® Sportster® Models
Stock Sportster models from 1981 to 1987 have two cable throttle system designed for butterfly type carburetors. 1988 to present models have a
two cable throttle system designed for use with the stock constant velocity (CV) type carburetor. Since the taller cable guide bracket can not be
used on a Sportster chassis due to insufficient frame clearance, throttle cables on motorcycles originally equipped with a CV type carburetor must
be changed to butterfly style cables. S&S can supply the correct style throttle cables. See S&S Throttle Cable Application Chart 1.

Chart 1
S&S THROTTLE KITS
S&S throttle kits fit 1" handlebars and can be used on most chassis. (An adapter sleeve is available for use with earlier, 7⁄8" OEM handlebars originally
equipped with internal throttle cable). Barrel fittings on S&S® cables readily "plug in" to S&S Super E, G, and stock H-D® 1981-'90 butterfly type
carburetor throttle linkage. Kits include one opening and one closing side cable, left and right grips, and handlebar clamps. Kits with 36", 39", 42", or
48" length cables are available. Length specified refers to overall cable length. Vinyl covered outer housing is 4" shorter than overall length.
NOTE: Cables supplied with above kits are interchangeable with 1981-'90 stock H-D butterfly style throttle cables.
3
S&S® Throttle Cables for 1996 and Later Chassis
These throttle cables feature the "plug in" cable fastener to fit 1996 and later throttle grips, and the correct length inner cable for use with S&S
butterfly style carburetors with the shorter cable bracket. These cables must be used in 1996 and later Sportster installations. These cables may be
used on 1996 and later big twin installations if the S&S carburetor is equipped with the short cable guide bracket.
CARB INSTALLATION
Read instructions thoroughly to familiarize yourself with all procedures before beginning installation.
NOTE: Installation of S&S Super E carburetor kits on certain models is easier with gas tanks removed. Some owners may elect to perform installation
without removing gas tanks. This is left to individual discretion. If installer elects to remove tanks or other stock parts, S&S recommends referring to
appropriate Harley-Davidson® service manual for correct removal procedure as necessary.
1. Remove Old Carburetor
••
••
••
WARNING
Gasoline is extremely flammable and explosive under certain conditions. Do not smoke around gasoline. Gasoline fumes are toxic
when inhaled. Perform installation in a well ventilated area away from open flames or sparks. Any gasoline leak or spill constitutes a
health and fire hazard.
If motorcycle has been running, wait until engine and exhaust have cooled to avoid getting burned during installation.
Electrical sparks can ignite explosive gasoline fumes. Failure to disconnect battery while working on motorcycle can also result in
inadvertent engagement of starter and personal injury.
A. Shut off fuel petcock and disconnect battery.
B. Remove air cleaner assembly. Drain fuel from existing carburetor. Remove carburetor, manifold, choke cable and any carburetor mounting
hardware.
NOTES: Removing and tightening hard to reach Allen bolts like carburetor mounting bolts and manifold flange bolts can be greatly simplified by using
some special tools. The S&S rocker cover wrenches work very well for this application. See Picture 3. Allen ball-end drivers are also very helpful and are
available at most automotive and tool supply houses. See Picture 4. As an alternative a standard hex wrench can be shortened for convenience.

thread locking product such as Loctite® 242 must be applied, and screws properly tightened.
CAUTION
Failure to apply thread locking compound or properly tighten screws may cause screws to loosen and fall into engine, causing engine
damage not covered under warranty.
A. Harley-Davidson® Evolution® big twin 1984 to 1992 and Sportster® models 1986 to 1990
1. 1992 big twin models with crankcase breather vented from cases to air cleaner backplate - Install thread-sert in each cylinder head air
cleaner mounting bolt hole. This converts stock 1⁄2"-13 thread to 5⁄16"-18 thread. Surface of thread-sert should be just below surface of
cylinder head. See Picture 16.
Picture 16
NOTES:
•• Most 1992 big twins have crankcase breather routed from case to air cleaner backplate. However, some late 1992 engines have breather routed from
••
••
heads to air cleaner backplate through air cleaner mounting bosses. If crankcase breather is routed through heads, 1993 and later carburetor kit must be
installed. Follow instructions for installation on 1993 engine.
Thread-serts may be supplied with or without thread locking compound on threads. Loctite® 242 or equivalent should be applied to threads of threadserts not supplied with thread locking compound. Thread-serts should be installed in desired position and left in place.
Installing thread-sert in hole activates thread locking compound making it difficult to change position of thread-¬sert after installation.
CAUTION
Cylinder head vent passages in "head breather" type engine must not be plugged as oil leakage and engine damage may result. Same
applies to crankcase vent in "case breather" type engine.

NOTE: Backplate screws supplied with kit have pre-applied thread locking compound on threads. If screw without thread locking compound is used, a
thread locking compound such as Loctite® 242 must be applied to threads, and screws properly tightened. If screws are removed in future, Loctite 242 or
equivalent must be applied before reinstallation.
CAUTION
Failure to apply thread locking compound or properly tighten screws may cause screws to loosen and fall into engine, resulting in engine
damage not covered under warranty.
7. Final assembly and checks.
A. Check carburetor to manifold mounting bolts.
B. Check carburetor to air cleaner backplate mounting screws.
C. Check each of following that is applicable:
1. Carburetor mounting bracket to head bolts.
2. Mounting bracket to air cleaner backplate.
3. Mounting bracket to center case stud.
4. Mounting bracket to tappet guide bolt.
5. Mounting bracket to head breather vent fitting.
6. Air cleaner backplate to head mounting bolts.
D. Check fuel line connections and routing. Avoid hot surfaces.
E. Check vacuum operated ignition advance connections if applicable.
F. Check crankcase to backplate vent hose connections if applicable.
G. Check fuel overflow hose routing. Avoid hot surfaces.
H. Test throttle to be sure it opens and closes freely. Turn handlebars to extreme left and open and close throttle, then turn bars to extreme
right and check throttle. When released, throttle should snap closed in all positions.
I. Reassemble components that were removed or disassembled for carburetor installation. Consult authorized Harley-Davidson® service

L. Install air cleaner element, noise reducer, and air cleaner cover.
1. Install three cover mounts and washers on backplate cover supports. Use Loctite® 242 or equivalent on threads. See Picture 26.
2. Install noise reducer on backplate over supports. See Picture 27.
3. Flat side of pleated filter element goes against noise reducer. Insure that element goes around outside edge of locating tang at 9 o'clock
position on backplate. Rounded side of element with S&S® part number goes toward outside. Correctly installed element will remain in
place on backplate without support.
4. Install cover using the three 1⁄4" -20” mounting screws provided.
Picture 27
Picture 26
NOTE: Pleated air filter element supplied in carburetor kits for big twins and Harley-Davidson® Sportster® models goes on dry. Do not apply filter oil to
pleated filter. Foam filter element may be installed dry or foam type filter oil may be applied. Foam filter elements may be washed and reused, but pleated
elements must be replaced when they become dirty or clogged.
M. Fill gas tank.
INSTALLATION NOTES: In designing the S&S® Super E carburetor S&S has made every effort to keep overall assembled length as short as possible. Due to
the short installed length of the carburetor assembly, the air cleaner cover may contact the gas tank of four-speed shovelhead chassis. In such instances
an optional chromed, notched cover that will provide additional clearance can be ordered. If a new, undamaged Super E/G cover is shipped to S&S
prepaid, it will be exchanged for the difference in cover prices. See your authorized S&S dealer for this service.
An optional 1" spacer block can be installed between carburetor and manifold as an alternative, or existing air cleaner cover modified to provide 1⁄8"
minimum clearance.
CAUTION
Improperly mounted carburetor may loosen from engine resulting in gas or air leaks, poor performance and possible damage to
carburetor or other components.
WARNING
Any gasoline leak represents a potential health and fire hazard.
12
CARB OPERATION
1. Carburetor Starting Procedure
S&S® Super E carburetors do not have a conventional choke. Instead, a mixture enrichment/fast idle device is used for starting and engine warm-ups.
The enrichment device utilizes separate air and fuel pickup passageways and is engaged by pulling fast idle level upward. See Picture 28. Super
E carburetors also feature an accelerator pump which is actuated by quick throttle movements at partial throttle openings and can be used as an
additional starting aid.
Picture 28
ENRICHMENT DEVICE NOTES:
Enrichment/fast idle pickup tube located directly below fast idle plunger is pressed into carburetor body and must not be removed. See Picture 29.
••
Picture 29
CAUTION
Removal of enrichment/fast idle pickup tube from carburetor body may cause irreversible damage to carburetor.
•• Plunger nut, plunger spring, and plunger, may be removed for cleaning purposes.
•• If air cleaner backplate is removed, be sure fast idle lever and enrichment plunger are engaged properly when backplate is reinstalled. See Picture 17.
•• S&S® enrichment system operates on manifold vacuum. If throttle is opened while starting engine, vacuum will be reduced and enrichment system will
not function normally.
13
A. Cold Starts
1. Open fuel petcock.
2. NOTE: When motorcycle is not running, fuel petcock/shutoff valve should be turned off to prevent possible leakage should needle and
seat not seal properly.
CAUTION
Gasoline leaking past inlet needle may flood engine causing oil contamination and engine damage.
WARNING
Gasoline leaking past inlet needle may flood engine and surrounding area creating a potential health and fire hazard.
3. Prime engine with one or more squirts from accelerator pump. Ambient temperatures below 60° may require increased priming, up to
6-7 squirts depending upon exact temperature and carburetor jet size.
4. Lift fast idle lever, to fully raised position.
5. Turn on ignition.
NOTE: Some engines, especially those equipped with magnetos, will start easier if given two prime kicks BEFORE ignition is turned on. For reliable starting,
magneto should be equipped with kill button to disable ignition for prime kicks.
6. With throttle closed, kick engine through or engage electric starter.
7. If engine fails to start immediately, crack throttle enough to barely open butterfly and continue to kick or engage starter until
engine fires.
8. After engine starts, position lever to maintain rpm at approximately 1000-1200 rpm with throttle closed. Lever may gradually be pushed
down to closed position as engine warms. Engine should be warmed sufficiently to idle with fast idle lever off in 1 to 4 minutes or after
a few miles of riding.
NOTE: Operating engine with fast idle lever up for excessive time will result in fouled spark plugs. Push lever completely down as soon as engine will run
smoothly without enrichener.
B. Hot Starts
1.
2.
3.
4.
Open fuel petcock.
Turn on ignition.
With throttle closed, kick engine through or engage electric starter.
If engine fails to start immediately, open throttle slightly and continue to kick or engage starter until engine fires.
C. Troubleshooting Tips - engine will not start:
1. Fuel supply exhausted.
2. Weak or no spark - discharged battery, worn points, faulty condenser, ignition module, coil, spark plug wires, or magneto.
3. Plug gap too wide - S&S® uses .025" to .030" plug gap on engines with points type ignition and stock coil. Electronic ignitions and high
output coils can run wider plug gaps.
4. Improper ignition timing - Worn or poorly maintained mechanical advance units sometime stick in advanced position causing hard
starting, kick-back and erratic idle.
5. Tight tappet adjustment - If solid tappets are adjusted too tightly, valves may not seat properly, and the loss of compression may
prevent the engine from starting.
6. Improper idle mixture and/or engine idle rpm setting. If idle mixture is set incorrectly, throttle plate must be opened farther with the
idle speed screw in order to maintain idle speed. This reduces manifold vacuum and makes the enrichment circuit less effective. See
Adjusting Carburetor -Idle Circuit on page 15.
7. If the enrichment device feed hole in bowl is plugged then clear with compressed air.
CAUTION
Do not use wire or drill to clear hole. If size of hole is changed, starting system will be altered and carburetor bowl irreversibly
damaged.
14
WARNING
Compressed air and particles dislodged by compressed air are potentially harmful to eyes and body. Wear protective goggles when
using compressed air and always direct air stream away from yourself and others nearby.
8. Improper diagnosis of rich or lean mixture condition. If engine backfires in carburetor, mixture is usually lean and engine must be
reprimed. If there is no response after three kicks or if engine pops in exhaust pipes, mixture is probably too rich. Leave switch on and
slowly open throttle 1⁄4 turn with each successive kick until engine fires.
9. If engine was running properly before installation of carburetor, no other changes were made and carburetor settings were confirmed
as instructed previously, hard starting is likely caused by incorrect intermediate jet or starting routine. Remain calm and patient while
attempting to start motorcycle, and experiment with different starting procedures (throttle and enrichener position, number of squirts
from accelerator pump, etc.), especially with kickstart motorcycle. Carburetor tuning and ignition tuning and maintenance are critical
for kick start motorcycles.
Notes:
••If severe flooding is suspected, turn ignition off, slowly roll throttle to wide open position, and kick 6-8 times to clear engine. Then close throttle
to approximately 1⁄8 turn, turn ignition on and kick until engine starts.
••If insufficient fuel is suspected, remove air cleaner cover and confirm accelerator pump operation by snapping throttle open from closed position.
Fuel should exit accelerator pump nozzle directly behind main discharge tube in carburetor bore.
••No more than 2-3 squirts from accelerator pump should be required to start motorcycle with temperature 60°F or above. This may also be caused
by incorrect idle mixture adjustment or a manifold leak. Refer to following sections for additional information on tuning.
2. Adjusting Carburetor
The carburetor comes preset from S&S®. It is illegal to adjust the carburetor to settings other than those provided in the documentation included
with the engine. In the case maintenance is needed the idle emissions and idle speed may be reset to the specification in the documentation by the
following procedure.
A. Adjusting Idle Circuit for idle emission – The idle mixture screw regulates air/fuel mixture at idle speeds and has been angled out for greater
accessibility. See Picture 30. Engine rpm adjustment screw is located on boss on rear side of carburetor body. See Picture 31. During
assembly S&S adjusts both screws to settings that should work for your application.
Picture 31
Picture 30

4.
Start engine and allow it to fully warn up.
Adjust idle speed by turning rpm adjustment screw.
Adjust idle emissions by turning idle mixture screw.
Verify idle speed has not changed.

GENERAL INFORMATION NOTES:
Carburetor body has six drilled passages that are permanently sealed with drive plugs.
••
CAUTION
Removal of these plugs may cause irreversible damage to carburetor.
•• To insure proper seal so needle completely shuts off fuel supply entering bowl, float hinge, needle lift and needle must work freely and not bind. Float must
not contact bowl gasket. If problem is suspected, remove bowl and check float movement. If obvious misalignment, binding or sticking occurs, remove,
straighten and reinstall to obtain free movement. Reset float level and double check for free movement. To check, remove bowl (not accelerator pump
cap) and raise float until needle is in closed position and spring in top of needle is compressed. The top of the float opposite the needle and seat assembly
should be 1⁄8" to 3⁄16" below the bowl gasket surface. Float must not contact bowl gasket. See cut away bowl in Picture 32.
Picture 32
•• When motorcycle is not running, fuel shutoff valve should always be turned off to prevent possible leakage should needle and seat not seal completely.
CAUTION
Gasoline leaking past inlet needle may flood engine causing contamination of oil supply and damage to engine.
WARNING
Any gasoline leak constitutes a fire and health hazard.
•• Throttle plate and throttle shaft should be checked annually for signs of wear. Replace if necessary. If carburetor body throttle shaft bushings are worn,
••
carburetor must be returned to S&S® for repair. If throttle plate is removed, be sure to reinstall correctly. Beveled edges of plate must fit flat against
carburetor throat.
If accelerator pump cap is removed, lift cap slowly so small spring, checkballs, and o-rings are not lost.
