How Is It Possible? A 5000cc V-Twin Attached on Motorcycle

[@nlo114]

He's a nice bloke, typical Brit project-engineer: If he couldn't buy something he'd make it. Quiet and unassuming, quite happy to chat and pass the time of day. He will go down in history as one of the great experimenters, making things just because he can.
