The upgraded versions of the proven HS40 flat slide carburetor deliver optimized performance for high-output Harley-Davidson engines. The main difference from the predecessor is the enlarged intake bore, available in 42 mm and 45 mm diameters, which significantly increases cylinder filling. The 45 mm version is specifically designed for large-displacement engines from 98 cui upwards or for racing applications.
Technical enhancements such as the two-piece flat slide running on precision stainless steel roller bearings ensure improved throttle response. A refined return spring offers smoother throttle operation and enhances rider comfort. Additional features include an idle mixture adjustment screw, enlarged needle valve, bigger float bowl, and an adjustable accelerator pump.
The result: excellent starting behavior, powerful torque delivery, and enhanced rideability across the entire RPM range. Installation is straightforward with the included mounting and tuning instructions. The original Harley-Davidson choke cable remains compatible.
