The “Power Tube” from Yost Performance Products adds performance to S&S and Keihin carburetors. It works by atomizing the incoming fuel to a fine mist. The result is better combustion, crisper throttle response and a smoother running engine. The solid brass construction is compatible with all fuels and comes complete with easy-to-follow instructions.
