Abstract: An operator-controllable valve opens or closes an idle air bypass passage in a motorcycle, allowing an operator astride the motorcycle to set an idle position manually. A handle permits a first adjustment by the operator without use of a screwdriver or other hand tool. An additional interface enables a wider range of adjustment using a hand tool. Both interfaces vary depth of an air mixture screw of the valve within an idle air bypass passage of a throttle body. Dual cylindrical members of the valve rotate relative to one another and relative to a base of the valve, each cylindrical member driven by one of the interfaces. Locking the cylindrical members together such that both rotate in tandem upon the operator moving the handle is accomplished by either tightening the handle or tightening a nut coupling the handle to the valve. A handlebar adjustment lever may couple with the handle.

Abstract: A mirror assembly for mounting to a handlebar of a motorcycle or other cycle vehicle, including a handle enabling an operator of the motorcycle to rotate the mirror without requiring the operator to remove a hand from the handlebar. The rotation swivels the mirror from a view to the rear to a position with a view to the side. Upon releasing the handle, a compression spring within the assembly returns the mirror to its original position. The mounting arrangement for the assembly includes two portions rotatable perpendicularly to one another, permitting the mirror arrangement to be adjusted after coupling with the handlebar such that the stem of the mirror is plumb. This ensures that when the handle is engaged rotating the mirror, the orientation of the mirror is maintained such that the top edge of the mirror remains level during rotation and that the mirror stem remains plumb.
