Mikuni: Performance V-Twin Carburetor Kits

Mikuni HSR42/458 Carburetor Kits

Mikuni American’s popular HSR42 and HSR45 Smoothbore Carburetor Kits are known world-wide as the best performing carburetors for American V-Twins, such as Harley-Davidson.

The popular Mikuni HSR42 Carb Kit is already an industry performance standard for Harley-Davidson Sportsers, Buells and stock Big Twins by offering a 25-percent increase in power and torque 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 large bore Mikuni HSR45 Carburetor Kit.

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 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. Mikuni HSR Carb Kits are designed especially for Harley-Davidson applications and bolt up easily to the engine’s stock intake manifold and use the stock cables and airbox.

Mikuni HSR42/45 Carburetors Kits for all model Harley-Davidsons and American V-Twins come complete and ready to run, usually without any re-jetting, however, additional jetting is included if needed.
