Mikuni HSR48 American V-Twin Carb Kit

American Big Twin Carburetors

The Mikuni high performance HSR48 Flat Slide Racing Carburetor is the must have for highly tuned increased displacement American Big Twin motor, such as Harley-Davidson.

This smooth-bore carburetor offers the highest air flow possible while providing highly accurate fuel metering, more power, and the renowned precision throttle response offered by Mikuni.

A new extended main jet and larger fuel valve assure ample fuel supply for very powerful and larger displacement Twin engines.

The Mikuni 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. Contact your local dealer to order and visit MikuniPower.com for more information. Mikuni American Corporation, 8910 Mikuni Avenue, Northridge, CA 91324.
