While riding the motorcycle, engine suddenly began making a loud clacking noise. Brought motorcycle in to Harley Davidson dealer and it was diagnosed that they cam chain tensior had become loose and was destroyed inside the engine causing small bits of metal to clog oil ports and damage the engine. The remedy was an engine replacement. Through deliberate research this appears to be an issue with the 2021-2023 model year Sportster S Harley-Davidson motorcycles and should be recalled to remedy the issue before engine failure due to manufacturing negligence.
