I had my seat off and saw the servo move when the bike started then went to the set position. I know the noise is coming from under the tank and it sounds like it's my throttle bodies. The throttle bodies make an adjusting noise when the bike turns on as well, but then they just keep ringing. No helmet on, its not too loud, but it's there.
I also related it to the throttle bodies because my bike idled for a minute the first time I started it up, then very very slowly died. The only way it didnt die is is I adjusted the position of the flaps with the screw on the side of the bike, and it runs fine now, but still has the humm
Side note, I did an engine swap, but didnt touch the position of the throttle bodies.
