Engine is and will always be the main visual component of any bike. I always love to customize my engines, making fin modifications, powder coating and changing the rocker boxes. During the V-Twin Expo I met with Nick Genender from NYC Choppers who showed me his new after-market rocker boxes. And I told him that I think they are superb and that I will probably need them on a next project. They are available for Panheads, Knuckleheads, H&L engines and even Twin Cams (a part to help me love TC!). See different designs and applications by going to NYC Choppers.
