I dont know to what extent you are mechanically inclined but I can tell you that you should not undergo this maintenance yourself if you do not have a service manual as a guide and if you arent totally sure what you are dealing with. More experienced wrenches will tell you it is not a very difficult job, but for a first timer it is time consuming and very frustrating. If you want to save yourself the aggravation and dont mind spending some money, I would recommend just removing the fork and taking it down to the local dealer and just let them know you need fork seals. From there you can pick out the seals you want. Obviously without seeing the bike I dont know if it is the stock fork or not, but my guess would be that it is the stock fork with aftermarket (independent suspension)springs, seals and internal components. In that case you will have a multitude of fork seal choices that will fit.
