Here's a few great videos from Youtube of a couple of truly classic engines firing up. The first is of course a Vincent motor that's been rebuilt and is out of the frame. This engine will soon be transplanted in to a custom bike being built by the guys at Machine Shed.
This second video is truly amazing. It's a 1915, 8 valve Indian Boardtracker. I don't know how this motorcycle or the guy sitting on it don't burst in to flames. Flames spew from every opening on the motorcycle each time he twists the throttle!!!
