Just bought this bike a month ago (my first bike) and noticed earlier today that it appears something may have fallen off or is missing. I dont know if I purchased it this way or way but given its location I am pretty concerned that I have been driving around without whatever it is. Can someone please tell me what should occupying the silver spot on these photos. There is a threaded hole where a screw used to be and something down in the hole. Bike is a 2011 Vegas 8 Ball. Thanks!
