Harley Davidson HSR42 Mikuni Easy Kit

 Mikuni HSR42 Carburetor Easy Kits
Mikuni American’s popular HSR42mm Series Smoothbore Carburetors are available in easily installed “Easy Kits” for all late model Harley-Davidson and other American V-Twin applications. Included are kits for 1990 to present 1340cc Big Twin engines, together with 1994 to present 1200cc Sportster and Buell S2 models. HSR42 Kits come complete with a properly jetted Mikuni HSR42 carburetor, installation instructions, and works with your stock throttle cables. Included is a special adapter that allows you to retain your stock airbox or use the higher flowing Screamin’ Eagle performance filter kit for an additional performance gain.

The HSR42 Mikuni flows more air at full throttle to produce more peak power than other carburetors with bigger venturi bores. While at smaller throttle openings the Mikuni's smaller, yet higher velocity flowing venturi, together with its advance fuel metering system provides a stronger overall powerband with improved rideability. On a stock engine without any other modifications you can expect the Mikuni HSR42 Carburetor Easy Kit to provide a significant 10% increase in power and torque, and up to a 25% increase in power and torque when matched to a higher flowing intake and exhaust system.
