King Kenny Roberts had a lot to say about the Yamaha TZ750: One, "It had too much of everything." And two, "They don't pay me enough to ride that thing." The legendary and fearsome four-cylinder two-stroke democratized racing by being available and affordable to anyone who brought money to a Yamaha dealer--no secret handshakes or "knowing the right people." The TZ750 transformed road racing, dominated Daytona, and had so much power it forced tire and chassis technology to keep up. Join Kevin Cameron and Mark Hoyer as they take a deep dive into one of the greatest racing motorcycles ever made.motorcycle racing, Yamaha TZ750, chassis development, two-stroke engines, racing technology, motorcycle engineering, racing history, motorcycle industry, racing strategies, motorcycle modifications

Carburetor tuning is often referred to as one of the dark arts, but a little study and some methodical work can yield great results. Kevin and Mark explore the intricacies of carburetor tuning while tracing the carburetor's evolution from early days of surface carburetors to spray carburetors, round slides, flat-slides and on to modern electronic fuel injection systems, sharing practical tips for enthusiasts.

Kevin and Mark talk about the major milestones and the other technologies and developments that forced chassis to change.

Piston aircraft engine development during World War II was vigorous (and goverment funded!) and the supercharged V-12 Two-Stroke V-12 Rolls-Royce Crecy was the next step. Single-cylinder and Twin test engines suggested as much as 5000 hp potential. Why didn't the Crecy ever power an aircraft? Join us!
