Here's a quick question. Recently removed the three threaded studs/rods holding the left foot peg and rear brake support. Reason: was removing the primary chain case cover. The bottom inch and a half long stud of the three was partially stripped and also gunked up with some sort of lock-tite or equivalent. So rather than just taking the nuts and washers off, took out the studs as well. I ran a die over the stripped outer threads and also a tap through the nut to even out the threads. I even did that to one of the other studs and nut. I noticed that after that the nuts for those two fit rather loosely, whereas the third stud and nut combination was tight - as it should be. Now this measured out with the "tooth" checker to see the number of teeth per inch and the outer side was 24 and the inner side was 18. All that for this question for machinists: was there a difference between tooth depth and width between what was produced in England in 1974 and what is now SAE here in the states? I don't want to "clean" threads up to find I've just made things loose or sloppy. It wouldn't matter, but I still have to replace the stud that was partially stripped. It has to go back in the threaded opening of the footpeg support base. By the way, it's not a show stopper and am more curious than worried.
