We've got a Harley Davidson Sportster 883. It's the 2002 model.

It was bought brand new. It was driven twice, then garaged for two years. It's still in the garage. We are selling it.

My question:

What is the correct procedure to safely start up this motorcycle for its new owner or potential owner? Do we have to do anything special to the fluids or doodads or doohickeys to prevent damage to it?
