The Racing Beat-designed Foam Air Filter Element for all 1971-85 Rotaries (except 1984-85 GSL-SE) consists of a polyurethane foam over a metal screen form that interchanges exactly with the stock element. The foam element can be re-used by periodically cleaning in solvent and re-oiling. While the element offers no significant increase in air flow when compared to a clean, stock paper element, as the paper element collects dirt its air flow capacity decreases dramatically while the foam element is nearly unaffected.
Racing Beat Air Filter Housing, Stock without Filter
Racing Beat’s dyno-proven Power Pulse Air Filter Assembly, for all 1971-85 Stock Carburetor Bodies, is designed specifically for performance. While the assembly uses the same Racing Beat foam air filter element that fits the stock canister, the design of the Power Pulse canister both improves air flow into the carburetor and limits the introduction of dirt particles into the filter element. The spun aluminum canister pieces are powder-coated white for added durability.
There is no provision for emission control valve hose/air pump hose connections on this assembly; however, there is a position available to connect a crankcase breather tube if needed.
