Around the 14 second mark. It happens often but I'd like to know if it is normal or something to check out. It sounds as if it reached a maximum point and can't go any more. It eventually goes away when I speed up faster or slow down. Usually only happens when I'm at a stop, and pressing the gas gradually until you can hear that noise.
The other noise I have is more of a wind kind of noise. Sounds like a very low hum like someone left the door open a crack and the wind was gushing through. If that makes sense? It was hard to record it but I think you can hear it at a complete stop and max volume in the above video.
