Now if you do this I AM NOT HELD RESPONSIBLE IF IT BREAKS I just grap it and move it up or down with a little force ya I'm sure its not the right way but it works
Remove the shield, put a thin wrench in next to the headlight and loosen the mounting bolt slightly if it's immovable. If you can't get the wrench in, remove the metal plate covering the triple tree (or rather, loosen, not remove) so you can move it around for better access through the hole. That should work.
