I've had this bike for 25+ yrs and rode it a bit back then. It broke a conrod bolt and I chopped 7lbs from the crank and fitted Carrillo conrods. I picked up a job lot of Hyde parts, this barrel among them, so bored and sleeved the cylinder to fit some 74mm Arias forged pistons I had. Up from 67mm so it became 903cc. Cams are stock so are the valves. Carbs are cheap and cheerful 32mm spigot as I welded on stubs yrs ago. I had Amals but they wouldn't clear the starter. Aftermarket starter works great as you can see. Thing makes about 60hp on the dyno, as much as a stocker does at the crank. Pulls like a twin. I hope to do another video soon showing about 6 Brits with buttons.
