Anyone have any tips on lubricating a headset? I'm helping put together a cheap Vilano/Purefix type bike, and out of the box, the headset scrapes a bit when rotating the handlebars. How to get it working smooth?

I'm surprised we don't have a maintenance sub-forum to ask about general maintenance tips etc. Seems odd to restrict these kind of questions to specific types of cycling. Maybe I missed a sub-forum?
