Russell’s Honda XR600 9 Cylinder 7893cc Radial Engine

Ian Drysdale thought we might want to know a little more about the Honda XR600 based 9 cylinder radial engine Russell Sutton is building that we mentioned last year, so he sent some more up to date photos. Ian’s working on the crankshaft and rods for the engine while Russell keeps himself busy with the rest of it.
