6- Install Air Cleaner Backplate

NOTE: Air cleaner backplate screws supplied with kit have thread locking compound on threads. If screw without thread locking compound is used, a

thread locking product such as Loctite® 242 must be applied, and screws properly tightened.

Failure to apply thread locking compound or properly tighten screws may cause screws to loosen and fall into engine, causing engine

damage not covered under warranty.

NOTES:

 Most 1992 big twins have crankcase breather routed from case to air cleaner backplate. However, some late 1992 engines have breather routed from

heads to air cleaner backplate through air cleaner mounting bosses. If crankcase breather is routed through heads, 1993 and later carb kit must be

installed. Follow instructions for installation on 1993 engine.

 Thread-serts may be supplied with or without thread locking compound on threads. Loctite® 242 or equivalent should be applied to threads of thread-

serts not supplied with thread locking compound. Thread-serts should be installed in desired position and left in place.

 Installing thread-sert in hole activates thread locking compound making it dicult to change position of thread-sert after installation.

Cylinder head vent passages in "head breather" type engine must not be plugged as oil leakage and engine damage may result. Same

applies to crankcase vent in "case breather" type engine.
