2002 HD soft tail Herritage Classic. At start up engine stalled frequently and has a cough or miss at cruizing speeds. appears like ignition may be cutting out. Had to run with enricher at 1/2 position even when engine was warm. Adjusted idle speed. Idle ok and can run with enricher in when warm, but still has cough at cruizing speed. Accelleration is fine.
Sounds like drumbanger is on the right track. If this bike ran ok in the past and you have not made exhaust or intake changes, the low speed jet may be partially plugged or you have developed an intake air leak. If this problem has always been there or you have changed something, consider going up a size or 2 on the low speed jet.
This sounds like your fuel jets need cleaned! also check ari fuel mix!
