I noticed that the next project bike will be a two stroke racer, with a Harris frame from the back of Brian Crichton's shed. It says that the frame was designed for a Yamaha motor. I'm curious what engine will be found to slot in there. I know the 250LC is an icon and all that but there's something simpler about air-cooled two strokes. An RD250/400 might be good or even an X7 motor assuming it'd fit. Does anyone else have an opinion?
