See Figure 1 and Figure 2. Some vehicle configurations have a different air cleaner assembly. Refer to Table 1 and check the VIN on the motorcycle to determine its configuration.
Rain Sock: Models Except APC
See Figure 1. For models with an exposed air filter element, water intrusion could occur in rainy conditions. When parked, water intrusion could result in internal engine damage. When running, water intrusion could result in engine misfire.
Install the rain sock over the air filter element in wet or rainy conditions to prevent water intrusion.
Removal
1. Remove air cleaner trim insert.
a. APC models: See Figure 2. Pull on front edge of trim insert to remove. When removing insert, only pull on the front edge without pushing in the middle. Otherwise the trim could be damaged.
b. Other models: See Figure 1. Remove two screws. Remove trim insert.
2. Remove screw to release cover. Remove cover and rubber seal (if equipped).
3. Remove three screws to release filter element. Remove filter element and bracket (if equipped).
4. APC models: Inspect the breather tube and fittings for cuts, tears, holes or signs of deterioration.
WARNING
Do not use gasoline or solvents to clean filter element. Flammable cleaning agents can cause an intake system fire, which could result in death or serious injury. (00101a)
WARNING
Compressed air can pierce the skin and flying debris from compressed air could cause serious eye injury. Wear safety glasses when working with compressed air. Never use your hand to check for air leaks or to determine air flow rates. (00061a)
5. Clean filter element.
a. Wash the paper/wire mesh filter element (and breather tubes) in lukewarm water with a mild detergent. Do not strike filter element on a hard surface to dislodge dirt.
b. Allow filter element to air dry or use low pressure compressed air blowing from the inside. Do NOT use air cleaner filter oil on the Harley-Davidson paper/wire mesh air filter element.
c. Hold the filter element up to a strong light source. The element is sufficiently clean when light is uniformly visible through the media.
d. Replace the filter element if damaged or if filter media cannot be adequately cleaned.
Installation
NOTE
APC models: Air cleaner mounting without installation of the breather tubes allows crankcase vapors to vent into the atmosphere. This violates emissions regulations.
