Just got a note from Kevin DeShazer about a little project he's working on in his basement. It's a three cylinder radial engine made from the cylinders of a Continental 0-360 aero engine.
The crankshaft comes from a Moto Guzzi. Three geared cams with Harley lobes operate the valves. It uses an aviation electric oil pump and that orange can on the front is an aviation alternator. Ignition is electronic and Harley hydraulic valves get air and fuel from a Mikuni carburetor. It displaces a healthy 2400cc. Moto Guzzi also provided the four speed transmission and rear end.
Kevin figures about another four months or so and we'll see it on the road.
Let's see, just take a few cylinders from an aviation engine, some valves from a Harley, crankshaft from a Moto Guzzi and the transmission and rear end while we're at it, fabricate a frame and Presto! we have a radial engine motorcycle. Cool! We'll be sure to keep you posted.
