For carbureted versions of the Harley-Davidson Road King, the carburetor is responsible for delivering the correct air and fuel mixture needed for smooth engine performance. Over time, fuel deposits, dirt, and varnish buildup can clog carburetor jets and passages, causing poor engine performance, rough idling, hesitation during acceleration, and difficulty starting.

Our Carburetor Cleaning & Fuel System Service restores proper fuel flow and engine performance by thoroughly inspecting, cleaning, and tuning the carburetor and related fuel system components.
