Tell me specifically, under what circumstances do you hear this noise? How fast is the engine going, what gear you're in, what you're doing with the throttle, stuff like that.

That's what I thought you would say. It isn't pinging. Most likely it's just the typical raucous clatter of a healthy YZF. Compare with another one.

Pinging will occur first at low RPM's in gear under a fairly heavy throttle load. Don't confuse it with chain slap.
