High-pitched tone
 

Hey to everybody ... I have a brand new Vaquero 2017. When I shut it off and stand there I get a high pitch that rings for about 10 to 15 seconds then shuts off then does it again and again for quite a while. I'm thinking it's coming from the radiator. I've never ridden a motorcycle with a radiator so if anyone else has this let me know what it is please.
