S&S Cycle jets are precision-produced jetting components for the S&S Super E and Super G carburettors that are among the most widely fitted performance carburettors on Harley-Davidson Big Twin and Sportster machines. The jet selection determines fuel delivery at various throttle positions, and finding the correct main jet and slow jet combination for a given engine and exhaust specification is the process that transforms a new S&S carburettor from adequate to optimally tuned. S&S supplies jets across a wide size range to allow builders to tune their Harley-Davidson carburettor precisely for their air cleaner, exhaust, compression ratio, and altitude. Starting lean and stepping up through jet sizes is the standard approach; having the correct S&S jets on hand makes the tuning process practical rather than a multi-week parts sourcing exercise.
