S&S Cycle Replacement Engine - Manual (Page 2)

2
Congratulations on purchasing an S&S® engine! Your new engine is designed and manufactured with the same care and attention to detail as those
used to set speed records and win races around the world.
This manual has been prepared to acquaint you with the operation, care, and required maintenance of your engine. It also notifies you of important
safety information and provides authorized service personnel with necessary emissions control specifications. Other S&S publications discuss
repairs and/or changes to the engine configuration. For information related to other components and systems on the motorcycle consult the
manufacturer’s manuals.
S&S Replacement Engines are legal for use in all 50-States as replacement engines in 1970-1998 Harley-Davidson® motorcycles originally equipped
with a carbureted, non-catalyst, big twin engine.
Per the tampering and defeat device prohibitions, under the Clean Air Act and California State law, it is illegal to remove or render inoperative any
device or element of an emissions control system, or to install any part or component that would bypass, defeat, or render inoperative any device or
element of design installed on the vehicle under the Clean Air Act or California State law regulations. This includes but is not limited to any changes
made to camshafts, fuel metering system, ignition, exhaust system or evaporative system.
ENGINE IDENTIFICATION NUMBER
The Engine Identification Number (EIN) is stamped on the left side of the crankcase below the front cylinder deck, and on the right side immediately
forward of the front tappet guide. It consists of a seven-character code (see example below). The first and last characters are stars (*). The second
character is a letter that designates the code for the model year of the engine. The final four characters before the star are the crankcase serial/
sequence number for that year. Some serial numbers will contain an eighth character between the year code and serial number.
Example: *G1234* represents crankcase sequence number 1234 that it was made in 2006.

CONTROLS AND GAUGES
The starter, key switch, engine-stop switch, throttle control grip, tachometer (if available), speedometer, oil pressure gauge, voltmeter, and fuel
gauge are discussed in detail in the motorcycle owner’s manual.
Enrichment Device
The carburetor uses a mixture enrichment device instead of a choke, but it is operated in a similar manner. During starting and operation before the
engine is warmed up, the lever located on the upper side of the air cleaner should be pulled up. When the engine is sufficiently warm, as described
in the OPERATION section, the enrichment device lever is pushed down.
Petcock
The petcock is located under the fuel tank as described in the motorcycle owner’s manual. On some motorcycles, the petcock operates automatically;
on others, manual operation is required.
Motorcycles with manual-operated petcock: petcock should always be closed when engine is not running to prevent accidental overflow
of gasoline and possible fire hazard or damage to engine.
Further information about the petcock may be found in the motorcycle owner’s manual.
