S&S Cycle Bore 4 1⁄8 V-Series Engines - Manual (Page 13)

b. Refer to the appropriate service manual for the torque
specifications of the inner primary housing transmission
mounting fasteners.
6. Tighten the four lower engine mounting fasteners to
35 ft-lbs.
7. Install the upper engine mounting bracket. Tighten bracket
to head to 35 ft-lbs. Refer to specific frame make/model year
service manual for torque specification of upper engine
mounting-to-frame fasteners.
8. Refer to the drive section of the appropriate service manual
for reassembly of the primary drive and case. Make certain
to install new chaincase lubricant if applicable.
IGNITION SYSTEM
NOTE - If installing the stock ignition from the removed engine,
refer to the ignition section of the appropriate service manual for
removal and installation.
1. Install the ignition timing sensor as per manufacturer’s
instruction, using provided ignition cover standoff screws.
Route ignition sensor wire through channel in lower part
of engine gearcase cover and secure with provided
retainer. If applicable, static time ignition as per
manufacturer’s instructions.
2. If applicable, install and connect the V.O.E.S. (Vacuum
Operated Electric Switch).
NOTE - V.O.E.S. - S&S ® Cycle does suggest the ignition system
selected for use with this 4 1 ⁄
8
" bore engine utilize the V.O.E.S.
(Vacuum Operated Electric Switch). Check the switch using a
hand vacuum pump with a gauge and set the switch to trip at 6
in. of vacuum-Mercury. See Picture 28.
3. Install the ignition manufacturer’s recommended spark
plugs.
a. Refer to ignition manufacturer’s suggested spark plug
gap and check spark plugs. Electronic ignitions generally
require a plug gap of between .038”-.043”.
b. Apply an anti-seize lubricant to spark plug threads,
install and torque to 11-18 ft-lbs.
4. Install and connect the ignition coil.
COMPRESSION RELEASES
1. Refer to included S&S Instruction Sheet #51-1065 or #51-1115
for wiring/cable routing of compression release mechanism,
if applicable.
EXHAUST SYSTEM
1. Install new woven-metal gasket into exhaust ports of
cylinder heads.
2. Inspect the exhaust pipe header flanges and retaining rings.
Replace if distorted, warped, or otherwise damaged.
3. Apply a high-temp. anti-seize lubricant to threads of exhaust
studs at cylinder heads.
4. Install exhausts to cylinder heads. Hand tighten exhaust
stud nuts.
5. Attach exhausts to lower mounting bracket. Shim if
necessary. Hand tighten mounting hardware.
6. Tighten exhaust flange nuts at head to 60-80 in-lbs.
7. Refer to specifications for the appropriate model and
tighten the remaining mounting hardware to the
recommended torque values.
In some instances, brake master cylinder must be spaced out
from frame to clear crankcase. UNDER NO CIRCUMSTANCES
SHOULD MASTER CYLINDER OR BRAKE LINE BE ALLOWED TO
CONTACT EXHAUST PIPE IN FINAL INSTALLATION. Heat
transferred to brake fluid may expand and cause brakes to
seize, resulting in possible fire hazard and loss of control of
motorcycle with injury or death to rider and others.
NOTE-Make certain that the exhaust system is not pre-loaded, or
in a bind, at the lower mounting points. Make all spacing
adjustments prior to final-tightening of the upper exhaust
mounting hardware at the cylinder heads. Failure to follow this
procedure may cause excessive vibration and result in failure of
exhaust pipes or mounting hardware.
