Hi to all, I have a 98 HD Dyna Wide Glide and it has new plugs and all the fluids have been changed, but still sometimes backfires or coughs when I accelerate, either at the first of a ride or anytime taking off during a ride, not all the time but sometimes. Could it be igniton problems or carb. problem? I don't know and any information would be apprecitated. Thanks, David McGraw Arlington, TX 98 Harley Davidson Dyna Wide Glide
