My forks seem to have risen in the top yoke such that over a cm of fork tube protrudes above the bars. the protrustion seems uneven left and right fork by a a couple of mm. You can see a spiral pattern on the top of the fork tube and I am on the 3rd ring. think this has happed over time when bolts seized so I slacken bolts off trying to unseize them. There only seems to be 1 allen bolt per fork leg the grips the top yoke to the leg 1 horizontal left and 1 right. when you slacken these should the fork pair lower triple tree front wheel drop in the top yoke. Or do you have to slacken the streering head bearings? What fork protrustion avove the handlebars in mm is normal? whats the steps to adjust? Thks
