These uniquely designed kits utilize your stock throttle cables for a quick install, and to retain your motorcycle's original appearance. The HSR flatslide carburetors deliver excellent throttle response and control. The smoothbore allows the engine to reach its full power potential, so you accelerate and pass with confidence. You'll get good gas mileage and many years of dependable, carefree performance. Mikuni HSR Easy Kits are designed to work with your original Harley-Davidson intake manifold, choke cable, air cleaner, and throttle cables.
