I will be getting my first Harley and I want to know what I'm working with and what I'm talking about. When someone asks me what kind of air cleaner I've got or what engine I'm running (which are just a couple things I know) I want to know what they are talking about and how to answer. Also, I want to know what & where each part is so I know what I'm looking at. . . Hope this makes sense and thanks in advance for any information you may be able to give. . .:o)
