HSR Series

Going fast has never been so easy! The number one performance carburetor for Harley-Davidsons and American Big Twins now slips onto any late model Harley-Davidson using the original throttle cables. Mikuni’s Twin Cam, Big Twin and Sportster / Buell Easy Kits even use Harley’s existing manifold, choke cable and air filter. Keep a Harley’s stock factory look and fit with better throttle response, improved acceleration, increased power and torque. Mikuni’s smoothbore, flatslide throttle with roller bearings, and accelerator pump technology delivers peak performance from idle to Wide Open Throttle. Available in 42, 45, and 48mm throttle bores for use with stock, mild, and highly modified engines.
