Hi Forrest,
You are using the incorrect markup id in your example, the correct markup id is beans_primary_menu
(refer to this reply for more info about finding the correct markup ids). If you want to have your navigation below the logo though, you will have to remove the float on the logo too. Here is the snippet:
beans_remove_attribute( 'beans_site_branding', 'class', 'uk-float-left' );
beans_remove_attribute( 'beans_primary_menu', 'class', 'uk-float-right' );
Another nice effect is to move the navbar below the header as such:
beans_remove_attribute( 'beans_primary_menu', 'class', 'uk-float-right' );
beans_modify_action_hook( 'beans_primary_menu', 'beans_header_after_markup' );
beans_wrap_inner_markup( 'beans_primary_menu', 'example_menu_inner', 'div', array( 'class' => 'uk-container uk-container-center' ) );
Happy coding,
