My main question here is: Is there such a beastie? I know the Honda 50 and the Chinese clone are only 49 cc but the law in AZ is that a motorized bike must be 48 cc or less. So I am wondering if it is possible to put a legal 4-stroke bike together. I know the cops won't know the difference but I have had worst case scenarios fall on me before so I'm wondering if it is possible to get by legally? Just because I'm paranoid doesn't mean they aren't out to get me!
