9- If the breather screws are used then the supplied breather hoses
are needed. The breather hose has a 90-degree bend with one end
longer than the other. Insert the longer end onto the barb fitting
of the breather screw. Insert the shorter end onto the barb fitting
of the bracket. The breather hose may need to be trimmed to fit on
some applications. See Picture 10.
10- If the button head cap screws are used then the supplied ¼" black
caps are needed. Insert the black caps onto the barb fittings of the
bracket. These caps prevent contaminants from entering the air
flow to the engine. See Picture 11.
11- Install the supplied O-Ring into the O-Ring groove on the face of
the bracket. The O-Ring may need to be stretched or compressed
to fit in the O-Ring groove. The O-Ring will increase in size when
heated above room temperature. See Picture 12.
NOTE: If the O-Ring is removed from a hot engine then the O-Ring may
need to cool before reinstalling it.
12. Locate the single bore tuned intake assembly, two 5/16" – 18 x 5/8" flat
head socket cap screws and the two air filters with clamps. Apply a
drop of blue threadlock to the screws. Verify that the O-Ring stays
in the O-Ring groove. Align the single bore tuned intake assembly
and torque the screws to 15 ft-lbs. See Picture 13.
13. Install the air filters and clamps onto the single bore tuned intake
assembly. Press the air filters on approximately 1-inch from the
tube ends. Tighten the clamps towards the end of the air filter
flange. See Picture 14.
NOTE: If the motorcycle is equipped with faring lowers then it may be
necessary to remove the glove-box from the faring lowers. See Picture 15.
