Mikuni American offers a HSR Performance Carburetor Kit for any Harley-Davidson, American Big Twin and other custom applications. The Mikuni HSR42 Carb Kit offers a 25 percent increase in power and torque for Sportsters, Buells and stock Big Twins when used with an aftermarket exhaust system. More mildly modified Big Twin engines with aftermarket cams and big bore kits can benefit from the extra induction flow provided by the larger Mikuni HSR45 Carburetor Kit, while the HSR48 Carburetor can satisfy the needs of the hottest tuned race motors.

All Mikuni HSR 42/45/48mm  smoothbore carburetors offer the highest air flow possible while providing highly accurate fuel metering, more power, and Mikuni’s renowned precision throttle response.carburetors are designed with an 8-roller bearing flat throttle slide assembly that allows an unobstructed venturi at full throttle to flow more air, while it carburetes more precisely at all throttle settings. Mikuni’s roller bearing throttle slide offers smoother throttle control and allows the use of a lighter throttle return spring for reduced throttle effort. And the Mikuni adjustable accelerator pump provides instant throttle response in any riding or performance application. While a high capacity float bowl prevents fuel starvation even under full throttle applications.
