Noise From Tank After I Turn The Key In The Ignition

Hi all I have a 2019 street twin. I recently removed the tank to sand off the old paint and once I reinstalled it I am getting a noise when I turn the ignition to on (not the engine). The whiny noise doesn't stop until I turn the ignition to off.
See video, any ideas would be greatly appreciated.

 

Thanks for the reply Smilinjack. Before I removed the tank the fuel pump would prime for a few seconds as expected. Now I hear the fuel pump priming along side the noise in the video. The fuel pump noise stops but the other noise doesn't stop until I remove the key from the ignition. I'll add another video so you can hear both sounds.

 

I'm pretty sure I have them on the right way. I remember making a mental note (not that my mind is as sharp as it used to be) I'll double check but wouldn't that prevent the bike from starting? I can start it up with no problem.

 

Hi yes I just checked and the breather hose is on correctly as well as the two connectors. I had the tank leaning on my leg just now and turned the ignition and the noise is not coming from the tank, it seems like it is coming from whatever is behind the silver perforated plate just behind the engine. I'll have to look up the name for those parts.

 

You kidding? if it wasn't for you I would still think it's the tank! Really appreciate all the responses!

 

I was worried about taking it out because of that noise but I'll take it regardless. Thanks.

 

Took the twin out for a ride last night and the noise has not gone away. I took off the intake cover and found where the noise is actually coming from. Check the video out, the piece is called the "throttle body assembly".

 

Hi, my bike is still making that noise. I've ridden it a lot since and the bike runs fine but the noise does not go away. Have you always had that noise or, like me, is it something that started recently? I've had the bike close to a year and it never made that noise before.

 

If you listen to the video you can hear the fuel pump prime and then stop the other noise keeps going. I've had the bike close to a year and it never made that noise before...and yes my bike runs great also but I'm a little curious why this noise started out of the blue.

 

The noise I have sounds nothing like that. I actually took off the throttle body, inspected and cleaned it, and that didn't help.
