I wanted to change the oil before the initial 600 mile service too, when I asked the dealer they said dont do it, there is different oil than what will be used after the first service and for the rest of the bikes life. They called it "break in oil" They also told me dont add any, just ride it. If I was really worried about it being low bring it in and let them look at it
They told me they put different oil in at the factory so the crap/shavings would flow out better during the first change. One of the techs said all kinds of shit comes out.
Truth? Dunno, but thats what they told me.
