Harley Davidson Carburetors
Mikuni HSR42 / 45 / 48 Carburetor Easy Kits
Mikuni HSR42 and HSR45, HSR48 Carburetors are the perfect carburetor performance upgrade kit for a Harley-Davidson Big Twin and other American V-Twin engines using a modified exhaust, cam kit, performance ignition, performance heads and possibly a big bore kit. The larger HSR45 Carburetor provides for significant more fuel mixture flow over Mikuni's very popular HSR42 Carburetor which is suited for stock and slightly modified engine where it allows a 25% performance gain.
