Then remove the cap from the top (it's spring loaded, so you need to give some force pushing down to avoid stripping threads out of the top as it is removed), pour some fork oil down until it runs clean out the drain hole (I like to heat it up first, so it's thin and flows easily out). Wait until that all drains, replace the drain bolt, fill the fork tube (mine specifies 12.7 oz on the right, 12.6 oz on the left), then pump the shocks up and down a few times. Once full, the oil level should be 7.6 inches from the top of the tube. Compress the spring and install the cap - that's probably the hardest part. There are tools to do this, lots of people have built their own - I think virgilmobile made a good one, as I recall.
I'm planning a fork rebuild on my bike this winter, so I'll be doing a how-to writeup at that time.
