Possible Causes for Metal on Metal Clunk
Loose exhaust bolts can trigger a metal-on-metal clunking noise in your Harley Davidson when it reaches high temperatures. This issue isn't only annoying but can also indicate potential problems.
When experiencing a metal-on-metal clunk during hot restarts, compensator issues might be at play. Ensuring the compensator is functioning correctly is crucial to prevent this noise.
