If the secondary breather passage is not used, cap it with the supplied
7/16" black cap. See Picture 3.
Brackets for S&S Super E & G carburetors will have a brass barb fitting
on the back of the bracket. See Picture 3. Attach the supplied rubber
tubing to the brass barb fitting. See Picture 4. Route the hose under
the gas tank or in an area of undisturbed air. Make sure the hose points
down and towards the rear of the motorcycle to prevent water from
entering. Make sure the hose does not kink.
4- Measure and record the bracket standoff thickness using a caliper
against a flat surface. If a caliper is not available then skip this step
and go to the next. See Picture 5, below.
5- Fasten the bracket and gasket to the carburetor or throttle body
face using the three supplied ¼" - 20 x 1/2" socket head cap screws
(torque to 90-110 in-lbs). There are two gaskets included in some
kits. One for S&S carbs and one for stock carbs or throttle bodies.
Verify that the threads of the screws have pre-applied threadlock.
NOTE: The gasket must be positioned evenly around the S&S® Super E or G
carburetor bore. If the gasket is too low then it may not seal at the bottom
of the bore and poor performance may result. See Picture 6, below .
6- The slots of the bracket standoffs must be aligned with the cylinder
head mounts. If the bracket is not aligned then determine if there is
enough intake manifold flexibility to position the bracket correctly.
If there is not enough flexibility then loosen the intake manifold
and adjust accordingly. See Picture 7.
NOTE: Make certain the intake manifold is fastened tightly before
continuing.
7- Measure and record the distance from the bracket standoff outer
face to the cylinder head mount face using a caliper. Calculate
the required shim thickness (shim thickness = bracket-to-head
distance – bracket standoff thickness) and select the shims that are
equal to, or no less than 0.020" of the calculated shim thickness. If a
caliper is not available then select and test different sized shims. An
assortment of shim thicknesses are supplied with each bracket kit.
Combine the appropriate shims to fill the gap between the bracket
and the cylinder head mount surface. See Picture 8.
CAUTION
If the shims used are too thick or not thick enough then damage
to the intake manifold and the carburetor or throttle body may
result. This can potentially cause leaks in the system.
8- Choose the supplied bracket mounting fasteners and washers
that fit your cylinder head mounts. The choices are 5/16" – 18 x 1-¼"
button head cap screws, 3/8" – 16 x 1-¼" breather screws or 1/2" – 13 x
1-¼" breather screws. Use the appropriate supplied washers for the
5/16" and 3/8" screws. Apply a drop of blue threadlock to the selected
screws. Install the screws while supporting the shims and torque to
15 ft-lbs. See Picture 9.
