Hi Grouch, Ok should be easy enough, if you look at the section front fork2 on the list you will see bolt number 37, I think this is your pinch bolt ie locks the spindle from turning, undo that ( take it right out) and the try to turn the spindle, you would be best to squirt some WD40 on the inside of the spindle where it goes through the opposite fork, that is the opposite side to the nut, that should be all you need to do mate. PS don't forget the bike will want to lean forward when you have the front wheel off so put a weight on the seat (as far back as you can) or chock the engine to stop it leaning forward.
