Fork seals can be a bitch but they can be done yourself. For me I did my seals this last winter. They were PIA!
I made my own seal pounder....
Then it was a 4# BIG hammer and alot of winging and cussing!!
Would I suggest a novice to do this? NO! I say remove the forks from the bike and take the forks to a shop for the tear down, and rebuild. And have them do the bushings with the seals. Then use a nice Ohlins synthetic oil over standard dino oil. I loved it when I did it on my 9R.
