A Harley may backfire under acceleration due to an overly rich fuel mixture, which allows unburned fuel to enter the exhaust system and ignite. This can also occur if there are issues with the ignition timing or if the spark plugs are worn or fouled. Additionally, exhaust leaks can contribute to backfiring by disrupting the proper flow of exhaust gases. Regular maintenance and tuning can help prevent this issue.
