The Mikuni HSR48 Flat Slide Racing Smoothbore carburetor for Big Twins is described by the company as "the must-have for any highly tuned, increased displacement Big Twin motorcycle engine."
Mikuni claims it offers the highest airflow possible while providing highly accurate fuel metering, more power and "Mikuni’s renowned precision throttle response. A new extended main jet and larger fuel valve assure ample fuel supply for very powerful and larger displacement engines."
Mikuni say their HSR48 offers all the same features and big performance gains as their popular HSR42 and HSR45 carburetors for stock and mildly modified Harley-Davidson and other V-twins. All their HSR 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 mixes fuel more precisely at all throttle settings.
Mikuni’s roller bearing throttle slide is designed to offer smoother throttle control and allows the use of a lighter throttle return spring for reduced throttle effort. The 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."
Ships complete with rubber mounting flange, choke cable, remote idle adjuster and additional jetting.
