Abstract: The objective of the present invention is to use the principle of an air jet to draw hot air away from the rear of a motorcycle engine for improved cooling, while shielding the leg of the rider from engine and exhaust heat. By reducing heat buildup, the present invention prevents heat discoloration of the intake manifold and carburetor and improves fuel atomization within the carburetor.

Abstract: Method for safely inspecting an atmospheric storage tank, located above ground or on a floating vessel, without having to empty the tank.
