A clunk going into first gear with the engine running is totally normal for the wet clutch in your RS. Your 2004 S has a dry clutch which disengages more completely that the wet clutch in your RS. Any bike with a wet clutch will clunk going into first gear, some more than others.
A wet clutch has oil between the clutch plates that allows it to spin the transmission input shaft even when disengaged. What you are hearing is the transmission input shaft stopping when the gears engage. The dry clutch physically separates the plates more and allows less input shaft rotation. Much of the time my '03 S will go into gear without any indication of engagement except for the neutral light going out.
Usually my RS will go into gear after a cold startup without any clunk, but that is the only time.
