Riding today I suddenly heard a funny noise that sounded exhaust related. Got home and saw that one of the studs and nuts that connects the front cylinder's header pipe to the engine was missing. I removed the other and saw that the stud is broken about 1/8" below the surface of the engine head. I sprayed some penetrating oil on it and watched a video on how to removed broken studs with easy outs. I know a good machinist. Should I try removing this myself or take it to the machinist? I guess worst case is that the easy out can break off. Is this a common thing with Buells?
