I havnt done it but I have looked into it. Search my friend, there are threads devoted to it. The trick to doing it is to pull the valve core and pour them in that way.
Speaking of searching, I went as far back as page 34 looking for your frame height. I found a post where you said it was at 26", however I am pretty sure you have adjusted your springs since then. So what is your frame height sitting at now? Any idea on how much up travel you have?
