I did mine on my 2005RT last year, as has been stated here very easy job, no real need for the Haynes manual if you done similar before. Couple of things to watch out for :
If you remove the forks completely like I did, be careful with the bolts that hold the lower fork legs to the bike, they are loctited in and very tight, it can be difficult to get a "square" fit down onto the Torx heads, so quite easy to round them out if you're not careful. The bolts are M8 Torx 40, probably best to get some new replacements to hand first, just in case, then you can replace them. Mine were chewed up by the time I got them out.
The fork sliders are not retained in the fork bottoms, so slide out easily, allowing you to completely drain all the old oil & clean the insides out. There are some small bleed screws at the top of the stanchions to allow the air to escape when you re-assemble them together.
If you do follow the Haynes manual, I believe the fork oil quantity is incorrect, I think it states 620ml per leg... but I'm sure 450ml is the correct value.
Replace the dust seals as well as the fork seals at the same time, they usually come in the kit together.
