S&S Jets

25 products — part of all Jets

S&S Cycle jets provide precisely calibrated fuel delivery for Harley-Davidson performance builds, giving riders and tuners the tools to extract the full potential from their S&S carburettors. Available through Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, S&S jets are engineered specifically for the Super B, D, E and G carburettor series that have equipped high-performance Harley-Davidson V-twin builds for decades. When you fit an S&S carburettor to a Harley-Davidson Evolution Big Twin, Twin Cam or Sportster engine, dialling in the correct jet sizing is fundamental to achieving the idle quality, mid-range response and top-end power that the carburettor is capable of delivering. S&S jets are machined to precise orifice tolerances that match the flow characteristics of the S&S carburettor body, ensuring that fuel delivery remains consistent whether you are tuning for street riding or higher-performance use. Using brand-matched jets removes a significant variable from the tuning process and ensures the calibration aligns with the carburettor's original engineering intent.
