I have been very impressed by this thread and have found it helpful, although some has been a little beyond my level. I would like to get your opinion on something. I have 2 bikes with Lucas
magnetos, a k1F and a k2f. For years I have been setting the timing by removing the center bolt that holds the points plate, and using a continuity light. i don't remember where I first came upon this method, but it is not in the manuals, and I have not seen it referenced anywhere. Typically, I see references to using cigarette papers or expensive boxes. While the method has always worked for me, the fact that I do not see it referenced anywhere makes me wonder if there is some reason, theoretical or otherwise, why I should not be using it. From your posts, you seem like you might have some thoughts on this method.
