How Can I Fit My Own Front Fork Seals?

Easily, if you have removed your seals, what I would do is go to home Depot, or to your ACE hardware store and buy a 1″7/8″ piece of plumbing plastic pipe about 3 feet in length.  Simply drop the seal over the fork tube, then slide the plastic tube over your fork tube and tap with a rubber mallet, this will fit smoothly and evenly and will not damage your seal.
