New to me 03 350 Rancher project

Hey everyone I just joined to forums, just bought my first Honda bike about a week ago and love my quad! 03 rancher 350 4x4es. Does the job for me lol . Anyways, when I bought it (second hand 13 000km) it was pretty much pink . Faded that bad from the sun. I ended up re painting it afterwards and ended up how it is now. I was wondering about a mid range rpm problem I recently encountered , when I’m in gear about mid range rpm, sometimes there’s a buzzing sound coming from the handle bar area or right underneath it. That area somewhere. I can’t figure out what it is , if someone can relate can you help me please? Loving my Honda she can go places I’m impressed lol:)
