When it comes to engine rebuilds, Hawg City combines old school craftsmanship with new tools and technology. The result is the best of both worlds: meticulous attention to detail and a higher quality end product. In our special clean engine room, we work on all V-twins, with a special expertise in vintage Harleys. And Winona Van Norman Cylinder Boring Machine and the Winona Van Norman Power Stroke Honing machine gives us the capability to bore and hone big cylinder motors, a service no one else in the area can provide.
