thanks for the reply Lever !
When you changed yours was it just drain and fill?
Someone told me there is a spring to compress when reinstalling the cap
If you just remove the top bolt you won't have to worry about the spring. There is a large plug that screws into the top of the fork tube that actually holds the spring in, and then there is the top bolt that screws into a threaded hole in the top of that plug. Remove the chrome cap on the top of the fork tubes, then you will see the bolt. You install the new oil through that hole in the plug, then reinstall the top bolt (make sure the seal is in place and still good). If you have a lot of miles, like 50k or more, then you might be better served to remove the forks entirely, tear them down completely, clean and inspect everything, and then reassemble with new bushings and seals. Otherwise, yes you can just drain and refill. Let the forks drain for quite awhile to get as much of the old oil out as possible. I think I let mine drain for about an hour while I went inside to eat dinner.
