- If gap exists, fabricate shim just thick enough to
fill gap

- Install opposite corner shim and mounting bolt
and nut, and tighten identical to other bolt.
9- Check other corners with feeler gauge to confirm
thickness required is same as before. If not,
determine cause and correct.

T124V engine installation in 1984-1999 design
m
otorcycle frame is essentially the same as stock, although
additional clearancing and shimming may occasionally be
required. When this style of case is solid mounted instead of
rubber mounted, additional care must be taken in installing
the case. Main areas of concern are between cases and frame
motor mounts. Checking clearance around and between case
mounting bosses and frame is necessary to insure that
crankcase r
ests squarely on motor mount pad and no stress is
applied to crankcases when mounting bolts are tightened.
Shimming may be required to compensate for variances
between frames.
Replace all other motorcycle components removed for
engine installation. Consult authorized Harley-Davidson
®
service manual for installation procedure for stock parts
not covered in S&S instructions.
NOTE- On certain models it may be necessary to switch the
shift linkage to the outside of the shift lever. Make certain
that there is clearance between the shifter rod and the engine
crankcases.
5- Ignition System Installation
A-
All Carbureted S&S T124 and T124V 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, r
etard, 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 ar
e necessary
NOTES
If the S&S IST ignition is not used, S&S recommends using
electr
onic ignition with adjustable advance cur
ve in S&S
T124 and T124V engines. Adjustable cur
ve permits
slowing rate of advance to control or eliminate pinging
under heavy load or when elevated temperatures or poor
quality gasoline encounter
ed.
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 pr
ecedence over the ignition manufactur
ers
instructions.
Timing that is too advanced will result in detonation and
engine damage. Timing that is too retarded will result in
e
ngine 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
w
arranty.
E
xcessive ignition advance
w
ill 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 “G”
carburetors, refer to included instruction sheet
51-1012.
2-
Engine assemblies supplied with Super “D”
carburetors,refer to included Special Application
Racing Carburetor Supplement for additional
information.
3- Engine assemblies supplied with fuel injection, r
efer
to included Induction System instruction Sheet.
B- Re-install and connect fuel tank.
1- Refer to appropriate service manual. Inspect fuel
lines and clamps - r
eplace as necessar
y
.
2-
Check fuel line connections and r
outing. A
void
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 star
t-up pr
ocedure.
4-
Double check that all fuel line connections have
been made correctly and there is no gas leakage
at any point in the system.
