42mm Carburetor Kit

The Mikuni Harley Davidson HSR42 Easy Carburetor Kit is a performance-enhancing upgrade for 1994-2004 Harley-Davidson Sportster 1200 models. This 42mm carburetor is designed to integrate seamlessly with your motorcycle's original intake manifold, choke cable, air cleaner, and throttle cables, simplifying the installation process. The kit includes a special air box back plate, an adapter for other CV-type air filters, and requires the use of the stock oval cover and a Screamin Eagle high-flow replacement air filter. The precision engineering and 42mm bore size are intended to optimize fuel and air delivery for a noticeable power increase. This unit is manufactured in Japan, reflecting a commitment to quality components. Fitment is specific to Harley-Davidson Sportster 1200 models from 1994 to 2004, including variations such as Custom Anniversary (XLH1200C), Custom (XL1200C/XLH1200C), Roadster (XL1200R), Sport (XL1200S/XLH1200S), and standard XLH1200 models within these year ranges. It is noted that the kit is for use on motorcycles still fitted with the stock plastic air-filter backing plate, and on some earlier models, the poly air box can foul.
