I've been riding on a couple occasions and the large nut in the center of my handlebars has rattled loose. I always hand tighten it and it hasn't slipped loose again in a while. I'm going to be putting a RAM mount over it soon and I wanted to torque it down properly. Does anyone have the torque spec for this nut? I couldn't find it in a service manual I found on another forum. Also, if anyone knows what the proper name for this nut is, what purpose it serves, and what size socket I need the information is greatly appreciated. Thanks!
