there is a stainless fastener in the right side of the head that i believe is part of the cam chain adjuster. I can turn it around and around one way, and not at all the other way. I pulled it out a bit with pliers to see if it would come out and it will, it doesn´t leak oil there but i´m worried it will fall out or leak. Also there is valve cover bolt hole that lines up with it exactly, but there are no threads and it won´t screw in, so its an empty hole in the cover for now. If anyone is fimiliar with this bike any help would be appreciated. Thanks.
