I got a 71 Shovelhead Superglide that I have been riding for about 3 months now. Up until 2 days ago the bike ran perfect, but yesterday on my way to work the bike started to break up at around 25-3000 rpm or around 50-60 mph. I have an S&S carb and drag pipes, and the entire ignition is electronic. I’ll have a chance to dig into it tomorrow, but I was hoping for some advice. I was going to pull the carb and do a full cleaning (maybe a piece of debris) and change the spark plugs.

Thank you
Ron
