Hi Group, New to the forum here. And my first cry for help. I just bought a 2002 Dyna Defender police bike with 2500 miles. It is completely stock. When i rode it, i noticed it would "cut out" whenever i was just maintaining speed or coming off of the throttle. It wouldnt stall, but it would sound like a "cough". But in the course of a mile lets say, it would do this often, never would do it when i would roll on the throttle and accelarate. I assumed since it had such low miles it may have done alot of sitting...so i have ran 5 tanks of gas through it, gave it sea foam gas treatment, and it still does it. I changed the plugs. The old ones were light tan and seemed fine. AT this point, i know i may need a dealer visit, but im thinking it may not be the carb but something electrical??? I did notice that the short plug wire doesnt feel real tight on the plug, even though you hear a click it still has alot of play. I also noticed that on the plug from that wire, the previous owner had a ton of dialetic grease on it. Could a faulty plug wire that doesnt fit real snug cause this type of problem?? As i said earlier, it runs great when getting on it, its just when at steady cruising speeds, it does that bucking, coughing, like something is not connected tightly. I know, its hard to diagnose, but any suggestions would be appreciated. Thank you for your time.
