Now I got this thing for a "crusty" early ironhead swingarm bike - with a slightly over stock or springer front end. Short rear fender (maybe with a steel tail-light hiked up?), peanut tank, flaking chrome, vintage seat, maybe a painted frame . . . A bike you wouldn't worry about leaving outside covered with tarp - with a log chain around it. Never wash it (wouldn't want to rinse the grease out).
We've had this 1970 ironhead engine with peeling chrome that would make a good mill....
