Fork Oil Change
Like any other maintenance procedure, it will vary with the type and frequency that you ride. I usually change mine once a year, but I don't ride every weekend. I just changed it and it had been about a year. This time, we completey disassembled the forks, cleaned everything and put in new oil. I chose Golden Spectro, but there are quite a few choices, with Mobil ATF being on of them. You can search this forum for more info, there is a lot of info out there. Fork seals... replace when they leak!!
Good Luck
PS. louis helped me with the forks, couldn't have done it without him.
