Ok I have an '89 electra glide classic with a stock 80 with no mods to exhaust or ignition system. When I start the bike in the morning it is hard starting and once it starts it runs terrible and the idle speed will surge and drop 300rpm and bounce back up. Once I have ridden it for about 15mins after letting it warm up first the bike runs great but until that point it coughs everytime I pull from a stop. I have done everything I can regarding the carb such as rebuilding it , new intake gaskets, and everything else fuel wise. Now I am beginning to wonder if I might have a problem electrically. What, if anything, could cause these problems.
