Thanks Al, When I look down on the top of the boss I would say that the top of the stud is about 1/2 millimetre below the top of the boss - like yours I would think. That means it will have to come out of the bottom. The exposed stud threads where the silencer bracket and nuts and washers fit is in a pretty poor condition, such that on a run last Saturday the nut must have come off leaving the silencer to move about the cylinder connection point. Thats why I started this post as the stud is proving extremely difficult to unscrew and I don't want to damage the boss. In fact up to now, after no end of WD40, it won't budge. I tried a bit of tapping on the end of the stud but that hasn't freed it. So now I will have to try a bit of local heat on the boss to expand it away from the stud threads. I just wanted to make sure that these studs were never Loctited in, but I suppose in 1954 when the bike was built Loctite didn't exist.
Was your stud easy to remove ? I really don't want to try brute force or the stud may shear off.
