You actually slide the forks up in the triple tree, which lowers the front end. You basically take the front fairing off, and handlebars, loosen the triple tree and slide the forks up about 1inch, I think you need to turn the schrader valves out so you can add air to them. This is a simplified explaination, there is a fair amount of time involved to do this, but I dont believe it is overly difficult. Guess it depends how handy you are and how willing you are to tear the front end apart. Think Wildbill in NC will do it for a fee, you mite want to contact him for more info.
