Hi Keith,
Welcome to the wonderful world of Triumph Trophy ownership. This forum, as well as the Yahoo forum, have been extremely valuable to me. Here's a link to the Yahoo forum:
http://autos.groups.yahoo.com/group/TriumphTrophy/
You'll find files with step by step instructions for trouble shooting and changing fork seals and dozens of other things. Also, these two forums have really experienced owners who provide timely, good advice for dealing with anything that comes up.
Most forum members use a Haynes manual. It's not 100% accurate which drives some of us crazy. I find it helps me alot. Between my Haynes and the great people on this forum and Yahoo, I feel 100% confident in my ability to fix anything on my bike (1996 Trophy 1200). If I choose to use a shop, I can get enough information to competently manage the repair.
Enjoy your wonderful bike and good luck with your forks.
