Maybe it wasn't flushed and there was still some old oil in it.
Do these things have a level indication?
If the level is right, start the bike and run it for a minute or so, watch the oil light. Then stop it, leave it a few mions to let the oil settle in the sump and check it again.
What I mean by flushing out, have a look at how it's done on a different type of bike -
