The popular Mikuni HSR42 Performance Carburetor Kits are the industry performance standard for Harley-Davidson Sportsters, Buells and Big Twins by offering a 25% increase in power and torque when used with an aftermarket exhaust system. All Mikuni HSR 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 for smooth throttle control with reduced effort, that allows an unobstructed venturi at full throttle to flow more air, while it meters fuel more precisely at all throttle settings. 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 offers two different HSR42 Performance Carburetor Kits for for Sportsters and Buells. One Kit, just for Sportsters includes a special airbox backing plate as shown to work with the stock oval cover and a Screamin’ Eagle high flow replacement filter. The other Kit, without the backing plate, works on both Buells and Sportsters with an aftermarket performance air filter assembly. The Mikuni Kits work with the stock push-pull throttle cable assembly.
