Hello I am from Russia. We are very bad with information on Harley. my bike is a sportster 1200 s. I was driving to work, the motorcycle began to twitch, at low speed I drove to the garage. The next day I started the motorcycle and saw black smoke. disassembled the carburetor, washed and blew, reassembled. the bike worked and then the spark began to disappear. At first it started up intermittently and then it stopped starting. as a result of the problem with the carburetor got a problem with the ignition. tell me where to start and what I might have done wrong. the bike is very simple with a minimum of wiring. keihin carburetor. sorry for my English))
On the ignition pick up in your nose cone. If the potting material is soft or looks like it is melted. It's a good sign it's bad. Ignition being weak will affect your mixture. I would address ignition and see if carb problem still exist.
