This is my first HD motorcycle and was wondering if the bikes fasteners, bolts & nuts are all American sizes? Is the bike made up of 100% American sizes or is it sprinkled here and there with a metric size? I own a late model Ford Mustang GT and it is made up of a mix of American & Metric sizes which drives me crazy when I work on it. So far, the little I have touched on the Dyna, has been American sizes. Thanks!
