NOTE - S&S ® Cycle recommends the use of Harley-Davidson ® oil
filters, part numbers 63805-80A (black), or 63796-77A
(chrome),or equivalent. The use of an oil filter designed for a
Twin Cam 88
® is NOT recommended.
All reference to Harley-Davidson ® part numbers is for
identification purposes only. We in no way are implying that any
of S&S
® Cycle’s products are original equipment parts or that they
are equivalent to the corresponding Harley-Davidson ® part
number shown.
3. Locate and install oil tank vent hose to fitting above the oil
pump on crankcase. See Picture 36.
4. Verify location of oil pump feed fitting on the pump cover
and install oil supply hose from oil tank. See Picture 37.
5. Fill the oil tank to the proper level.
NOTE - S&S Cycle recommends the use of Mobil ® 1 V-Twin
20W-50 synthetic oil in our engines. If not using Mobil 1, see

FINAL ASSEMBLY
1. Refer to service manual for installation of foot rest
assemblies if removed for engine replacement.
2. Reassemble transmission shift linkage if necessary.
NOTE - On certain models it may be necessary to switch the shift
linkage to the outside of the shift lever. See Picture 38. Make
certain that there is clearance between the shifter rod and the
engine crankcases.
3. Reinstall and connect the fuel tank. Refer to appropriate
service manual. Inspect fuel lines and clamps - replace as
necessary.
a. 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.
b. Reassemble components that were removed or
disassembled for installation. Consult authorized Harley-
Davidson
® service manual for installation procedure for
stock parts not covered in S&S instructions.
c. Check fuel needle and seat assembly. Fill gas tank with
just enough fuel to test system. Lean motorcycle over
towards carburetor side, turn on fuel petcock and wait
20 seconds. If gas runs out end of carb or out overflow
hose, turn off petcock and check needle and seat.
d. Check fuel inlet fitting and fuel line connections for
leaks. Hose clamps must be tight.
NOTE - Fuel needle and seat assembly must completely shut off
fuel supply to carburetor bowl. Fuel inlet fittings and fuel line
connections must not leak.
Gasoline leaking past inlet needle may flood engine causing
contamination of oil supply and damage to engine.
Any gasoline leak represents a health and fire hazard.
INITIAL START-UP
1. Remove tappet screen plug and screen assembly from
crankcase. See Picture 39.
2. Remove wires from spark plugs. Ground plug wires to
cylinder head with either a jumper wire or through a
test plug.
It is possible to damage certain types of electronic ignitions if
the high-tension side of the ignition coil is left open. Always
ground the spark plug-side of ignition coil when turning
engine over.
3. Engage manual compression release, if applicable.
4. Turn ignition on and turn the engine over with the starter
motor until you get engine oil at the tappet screen port.
Avoid excessive time of starter engagement. Overheating of
starter motor will result in damage. After 30 seconds of
continuous starter running, allow 5 minutes for the starter
motor to cool.
