cam chain question?

[mrflagstaff]

ok so ive researched my problem and may have come to a diagnosis based on others experiences with the clunking: its rpm related but only between 4-6k rpm and it doesnt effect performance at all just a noise. so should i assume that it is the cam chain loose. its a metal to metal sound stays same rythm but goes away at certain rpm
