Okay, so I went and checked out my bike and their is rust in the fuel tank with about a gallon or two of fuel in it still. 1.) How do I get rid of the fuel in their as in dispose of safely? 2.) How do I get the rust out of the tank and stop it from rusting? 3.) What can I do to protect the inside of the tank from contact with the fuel? All suggestions are welcome and how you you guys done this?
