No, he is hearing the cam chain, alright.
I am hearing it too.... but it appears to be a normal characteristic. Don't think there is anything to be concerned about.
On my K8 (~3000 miles on the motor), the cam chain noise I am hearing is not obtrusively loud; it appears predicable and consistent. Having dealt with Genesis engines from Yamaha for many years, I am fairly sensitive to cylinder head noises/harmonics. What I am hearing from my K8 cam chain doesn't concern me at all.
