It could be detonation from low quality/low octane gas or ignition timing/advance, too. The engine tries to "pre-ignite" the fuel charge due to elevated temperatures in the cylinder. Maybe the spark plug tip remains hot enough to cause this condition?

I would check out your spark plugs and see if they have the appearance of the "OVERHEATED" spark plug in the photo attached.
