Normal engine sound?
I took a short video of my 2001 Road King , it has a big bore kit, gear drive S&S cams, etc.
I think the bike has always sounded like this, but is the noise in the top end area just normal operation? The bike is loud with true dual fishtails so i had to get right beside it to pick up the other sound.

Is this a new build that has been through break in and tuning? I can hear the noise; not normal and sounds like rocker arm noise from valve train lash. 2001 ran double wound straight springs and with hihger lift cams the springs could come in contact with the rocker cover. If roller rockers, for sure the rocker covers need to be clearance in the corners. Pull the rocker cover and look for witness marks from contact. I had to clearnce rocker covers for .600" lift cams in a 2002 motor because of contact.

In the video I took , the phone is right next to the rocker boxes. If I just start it and stand off to the side you cant hear anything unusual.

So, if you are far enough away and can't hear the "not normal" noise, it's OK to ride until something breaks and you can't ride and you have to spend money so you can ride again?
C'mon man, two of us have told you the noise is unusual and should be investigated and others will likely tell you the same. However, it's your ride so do what you want; I can only tell you what I would do in the same situation.
