Abstract: An adapter assembly includes an adapter body extending from an adapter inlet to an adapter outlet, a canister mount for securing the adapter body to an air filter canister, and an adapter joint for securing the adapter body to the canister mount. The canister mount includes a collar that is secured about the air filter canister. The adapter joint allows the adapter body to be moved away from the air filter canister for air filter replacement without having to disconnect the adapter body from the air filter canister. Precleaners are airtightly securable to the adapter body inlet, and the air filter canister is airtightly securable to the adapter body outlet. Air cleaned by the precleaners before reaching the air filter has less contamination to be filtered by the air filter before the air flows into an engine. Precleaning significantly extends the life of air filters.

Abstract: A device for securing a motorcycle to a surface such as a trailer bed includes a base assembly attached to the surface and including a base plate and a pair of eccentric pivot support brackets, a pin assembly, an eccentric pivot rotatably mounted to each of the eccentric pivot support brackets and having an aperture formed therein such that the height of the aperture is adjustable by rotating the eccentric pivot, and a pin bracket attached to a motorcycle. The motorcycle is secured to the surface by positioning the motorcycle with the attached pin bracket over the base assembly attached to the surface and using the pin assembly to connect the pin bracket to the apertures in the eccentric pivots. The rotatable eccentric pivots allow the device to be adjusted for use with motorcycles having various ride heights. Locking structures are provided for locking the rotational position of the eccentric pivots with respect to the eccentric pivot support brackets after such an adjustment is made.
