I have a roadking FLHRI and have low idle issues and sometimes dies at stops but cranks back up any suggestions on what to ck first?

 

Check for intake leak with carb cleaner first, If it's got the MM injection, pull the cover off and use carb cleaner to clean air bleeds at 10 and 2 in upper part of intake. You may have a hose in fuel tank leaking also. Mine was the air bleeds in intake dirty. Cleaned them, now idles cold about 1200 and warm between 950 and 1000 rpms.
