Why is there a pinging noise in the motor of my 2007 Harley Davidson?

Pinking or pinging is caused by incorrect timing or incorrect gas type or gas/air mixture too weak. Always run on the recommended gas or an additive if the correct gas is not available. As a 2007 is fuel injected, it is near impossible to set up the timing and mixture without dealership workshop equipment.
