The HSR48 offers all the same features and big performance gains as the popular Mikuni HSR42 & HSR45 Carburetors for stock and mildly modified Harley-Davidson and other V-Twins. All 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 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. The new HSR48 comes complete with rubber mounting flange, choke cable, remote idle adjuster and additional jetting.
