Front wheel wobble

Ive only had my bike a month and put just under 500 kms on it and its suddenly developed a heavy front end wobble while im riding with no hands. I checked some videos and everything seems good from what i can tell. The wheel doesnt shake differently from the frame and the big bolt down the center of the handle bars is tight. Anything else i can try before taking it to the shop?
