11-2055 Throttle plate, B/E carbs

This S&S throttle plate is designed specifically for use in 1-7/8 inch diameter B and E series carburetors. As a central component of the throttle body, this brass plate regulates airflow into the engine, directly impacting idle stability and power delivery. The precision-stamped brass construction ensures a perfect seal against the carburetor bore when closed, while providing smooth rotation throughout the throttle range. S&S throttle plates are manufactured to strict tolerances to maintain the performance characteristics that Harley-Davidson riders expect from these iconic carburetors. This replacement plate is sold individually and is a necessary component for restoring the functionality of older B and E series units.
