I ride 2003 heritage softail. Is dying out at stop light when idles and takeoff. Does it intermittently. Is always cold blooded and choke on until warm up engine but dying out is a concern and will backfire right before it dies sometimes.

a "backfire" is an indication of an ignition fault.

an ignition fault can be caused by a problem with the ignition module or the voltage applied to it.

- IF you have a crane HI-4 ignition, replace it.

- if not, measure the battery voltage under the following conditions:

- ignition OFF

- ignition ON.

- with the start button depressed.

- with the engine at about 2,000 rpm (fast idle)

It was a carberator issue and float. No ignition fault was diagnosed.
Expert:  Steve replied 2 months ago.

a carburetor issue cannot cause a "backfire".

a backfire can ONLY because by an ignition issue.
