How to Change a Choke Cable on a Harley

Harley-Davidson always calls its choke cable the "enrichener." Pulling the enrichener knob out increases the percentage of fuel in the carburetors fuel/air mixture, which helps cold engines start. Pushing the knob in returns the fuel/air mixture to normal levels. This is a small and inexpensive component, but many riders hesitate to replace the enrichener themselves because written instructions for the procedure are non-existent. Replacing the cable assembly requires at least the partial removal of the carburetor. You can remove the carburetor completely, but if you leave the carburetor loosely attached to the intake manifold, the throttle cables and fuel line remain intact.

Instructions

1

Empty the carburetor of fuel by closing the petcock and starting the engine. Let the engine run until it stalls.

2

Remove the entire air cleaner assembly, including the air cleaner cover, the air cleaner and the air cleaner backing plate. Use an Allen wrench to remove the cover, Torx sockets or drivers to remove the air cleaner and a socket wrench to remove the backing plate. Disconnect the breather tubes by hand.

3

Detach the enrichener knob from the bracket above the horn.

4

Pull the carburetor partly out of the black, rubber seal ring that connects it to the intake manifold. Use a flashlight or shop light to locate the enrichener cable and find where it screws into the carburetor. Remove the old cable by unscrewing it.

5

Clip the knob end of the new enrichener assembly into the bracket above the horn. Snake the enrichener valve end of the new enrichener cable assembly under the gas tank to the back of the carburetor.

6

Insert the wire and ball end of the enrichener valve into the opening in the back of the carburetor. Thread and hand-tighten the black, plastic cable sealing cap on the end of the enrichener assembly to the back of the carburetor. Do not use a wrench.

7

Reseat the carburetor in the seal ring. Visually inspect the carburetor. Reattach the entire air cleaner assembly, including the breather tubes.
