The guy that tuned my bike heard that too. He played around with the mapping to see if it was detonation but in the end, decided it was the cam chain.

well perhaps anyone can contribute with this one..

when you accelerate hard can you hear a metallic rattle coming perhaps from the valves which settles down after you keep the trottle steady at some specific rpm?

I'm afraid that this sound is probably pinging coming from detonation from starvation. With the akrapovic map is a little less but it's there.
