1. Remove existing air cleaner assembly and
related hardware including cylinder head
breather fittings if applicable. Refer to
authorized Harley-Davidson Service Manual as
needed.
NOTE - Hose barb on rear cylinder head breather fitting
must be removed. To remove fitting from cylinder head,
a cut-off wheel or similar tool is used to cut barb off.
Care must be taken that no metal chips get into the
breather fitting. S&S recommends packing fitting with
grease. An alternative is to grasp barb with pliers and
snap off.

NOTE - Breather fitting o-rings are easily damaged. It
is suggested that replacements be obtained prior to
removing breather fittings in future.
4. Repeat for other breather screw.
5. Pass breather screws through breather fittings
#17-0337 and OEM support bracket. Do not
tighten at this time.
NOTE - At least one .125” shim must be installed
between breather fitting and cylinder head. Otherwise
breather screw may bottom out in cylinder head,
resulting in oil leak and possible damage to head or
screw. (See Picture 4 Item B)
6. Install backplate on carb.
NOTE - Backplate screws supplied with this kit have
thread locking compond on threads. If screw without
thread locking compound is used, a thread locking
compound such as Loctite 242 must be applied, and
screws properly tightened.
7. Remove backplate and breather screw
assemblies, then install shims and reinstall
breather screw assemblies. Do not tighten at
this time.
8. Align breather fitting outlets to permit installation
of T-hose.
9. Install rubber T-hose #17-0339 over cylinder
head breather fittings with hose tee toward rear
of engine. Hose must not be kinked or otherwise
obstructed, and should be trimmed to length
as needed to align tee with backplate cut out.
Once proper fit is obtained, secure T-hose to
breather fittings with black tie-wraps or clamps
provided.(See Picture 4 Item C)

equivalent to threads, install nuts and
lockwashers.
14. Tighten all mounting hardware.
15. Install filter element and air cleaner cover. Secure
with three air cleaner cover screws #50-0072 to

WARNING - Vent hose must not contact hot or
moving surfaces that could damage it and expose
brakes or tires to crankcase oil/air mist. Oil on these
components could result in loss of control of
motorcycle with death or severe injury to operator
and others.
16. Start motorcycle, inspect for leaks, and test ride.
Engine should run smoothly after proper warm-
up. Surging or misfire may indicate lean
