Simple installation and easy adjustments make the Mikuni "Easy Kit" one of the best and most popular ways to improve the performance of a Harley-Davidson motor. Easy Kits use the stock intake manifold and stock throttle cables making installation very simple.

The HSR's unmatched throttle response and excellent air/fuel mixture control gives it a clear advantage over its competition. The design evolution of the Mikuni HSR carburetors goes back more than 80 years and stands at the end of a long line of excellent motorcycle carburetor designs.

Easy Kits for the Twin Cam and Evolution models add both power and all around performance to stock or moderately modified engines. With a free-flowing air cleaner and mufflers a Twin Cam motor picks up a solid 15 Horsepower. A similar Evo gains 12 or more.

These kits are designed to work with your original Harley-Davidson intake manifold, choke cable, air cleaner and throttle cables. You can run other high performance air filters designed for the CV type carb by using the special adapter included in the kit.

Includes 42mm carb, air box adapter and instructions. Twin Cam uses the stock oval chrome cover. Evo uses the Screamin' Eagle air cleaner or most aftermarket air cleaner assemblies
