S&S Cycle T111 Engine Assembly - Manual (Page 6)

5 - Ignition System Installation
A- All Carbureted S&S T111 assemblies come with an S&S
IST (Intelligent Spark Technology) ignition. Use of this
ignition system is highly recommended. All aspects of
ignition timing- advance, retard, and curves are
handled automatically by the S&S IST ignition.
B- Once the IST ignition has been installed per the
included instruction sheet 51-1155, no other
adjustments are necessary
NOTES
G If the S&S IST ignition is not used, S&S recommends using
electronic ignition with adjustable advance curve in S&S
T111 engines. Adjustable curve permits slowing rate of
advance to control or eliminate pinging under heavy load
or when elevated temperatures or poor quality gasoline
encountered.
G All other ignition systems other than the included S&S IST
ignition install per manufacturers instructions.S&S
recommends setting the total ignition advance to 28
degrees. Timing degree recommendations given by S&S
take precedence over the ignition manufacturers
instructions.
Timing that is too advanced will result in detonation and
engine damage. Timing that is too retarded will result in
engine over-heating and engine damage. (This caution
applies only to installations other than the S&S IST Ignition)
If S&S determines that engine damage was caused by
improper ignition timing, repair will not be covered under
warranty.
Excessive ignition advance will cause engine to kick back
against the starter during start-up and “buck” when ridden at
steady speed with partial throttle. An advanced condition can
also cause pinging or ignition knock and possible piston
damage. These symptoms may not be noticed if electronic
ignition with “soft” advance curve is used.
Excessive ignition retard causes sluggish performance and
severe overheating with possible subsequent damage to the
engine, and must also be avoided. Immediate or rapid exhaust
pipe discoloration is usually a sign of retarded ignition timing.
6 - Fuel system installation and tuning
NOTES - S&S ® Engine assemblies are available with either
carbureted or fuel injected systems.
Assembled Engines are shipped with the carburetor or fuel
injection system installed. Refer to the included instructions for
operation and tuning .
A - Install fuel system.
1- Engine assemblies supplied with Super “E”
carburetors, refer to included instruction sheet
51-1012.
2- Engine assemblies supplied with fuel injection, refer
to included Induction System instruction Sheet.
B - Re-install and connect fuel tank.
1- Refer to appropriate service manual. Inspect fuel
lines and clamps - replace as necessary.
2- Check fuel line connections and routing. Avoid
hot surfaces. Make certain that the protective
cover has been placed over fuel line, and that it
is clear from sharp edges and abrasive surfaces.
3- Fill the fuel tank with a sufficient quantity of
gasoline for the initial start-up procedure.
4- Double check that all fuel line connections have
been made correctly and there is no gas leakage
at any point in the system.
