The noise only happens at that time. Now when I say a "rip on the throttle" I'm not talking about redlining it or anything. If the noise only happens when I do that then that tells me that there is something underlying that could end up damaging something. That's what I am trying to avoid
I know what the "rip on the throttle" is, I hear it all the time from other riders and as a long time member of the Harley universe find it annoying. Trying to think on this logically, we have to think about what happens when you blip the throttle. The first thing that comes to mind is that the motor, which is rubber mounted, will move under throttle action. If the motor mount(s) are loose enough, the motor or something attached to the motor, could move enough to contact another part of the motorcycle. Jackie Paper as mentioned this possibility in a previous post. It would be a good idea to check the motor mount.
If you take the bike to the dealer, please let us know the outcome.

So they do have a wirr noise. Not like a car with steel running is softer bearings.
Be for warned. It's a statistic fact. Few dealer ships are honest.
It they take you for a easy cash cow, they may look for something. Just opening up cost big bucks today. If it's under warranty and Harley's footing it, that's probably different.
You can find it yourself.

If there was something really wrong, you would here it constantly and with a two ear mechanic stethoscope, it's very noticable as a rough rumble. Harley's are full of steel roller bearings with steel rolling on steel.

I see from your OP that you are a new member, welcome to the forum. I also see that you are a new Harley owner, welcome to the Harley universe, there is much to learn. If the bike is starting and running normally and this "clank" is the only issue you have, it is very unlikely that anything will be damaged. It is also very likely that the noise you hear has nothing to do with the mechanical operation of the motorcycle.
I know what the "rip on the throttle" is, I hear it all the time from other riders and as a long time member of the Harley universe find it annoying. Trying to think on this logically, we have to think about what happens when you blip the throttle. The first thing that comes to mind is that the motor, which is rubber mounted, will move under throttle action. If the motor mount(s) are loose enough, the motor or something attached to the motor, could move enough to contact another part of the motorcycle.

Thank you both for your thoughts. I know that there going to be tons of little noises to expect. I didn't think anything about it until it was someone in a car that noticed and said "what was that? Is something loose?" Thankfully it is under warranty and I have a friend that works at one of the shops as a parts manager so I really just want someone to hear the noise really

All of the above are good suggestions.
Here's an odd suggestion, though.......
Make sure the screws that attach the voltage regulator to the frame are installed and tightened to specs.......sometimes when the engine revs, and this is loose, it can clatter against the downtimes.
Just a thought

That's not the transmission. That motor sounds so smooth otherwise. Mine at 50 k makes so much racket at idle , you wouldn't here that if it did it.
That little shake from the hip is rattling something. Might be nothing loose . Just something thin enough to do that. Even a exhaust shield.
I'd be probing everything. I have 3 different length pipes that attach to my stethoscope . But I been working on car since the 60s.
Does your engine have the variable valve timing? There's also a anti black lash in your balance cam.

I guess I am really just looking for piece of mind, that noise isn't going to screw with anything major. And of course without getting it in front of someone that knows more than "push that to start, twist that to go and listen to the vroom" lol

That noise is not one I have ever heard before but does not sound like contact between components. I would like to see a video of holding the throttle open instead of just a quick twist and see how the noise presents.
