Daytona Postscript (Above) Daytona was touted by some as the start of the aerodynamics era. Gary Nixon's En Kanemoto experimental fairing-shod TZ750D never made the starting grid. Nixon broke his arm when his Harry Hunt 250 seized In Tum One during lightweight practice. Steve McLaughlin had another, more radical experimental fairing, but was so plagued with motor problems that he never was In the hunt, and didn't finish. (Left) Not many people have seen this face before. It's Eddie Lawson, the Daytona Novice race winner. Lawson doesn't boast or brag much. He Just flat flies. (Below left) The Kel Carruthers-designed frame for Baker's 250 was just like the one Kenny had, but needed a little work to make the aerodynamic seat - a Carruthers scaled-down copy of the factory TZ750D experimental fairing seat - fit to Bob Work's · satisfaction. Three Inches lower, 30 pounds lighter than a TZ250, and pulling three less rear sprocket teeth at the same top gear rpm as last year, the Roberts and Baker 250s were the class of the 250 race. On the first lap of his heat race, Baker pulled up to, around, and past the TZ250 of early leader Wes Cooley on the banking like Cooley's bike had it in reverse. The bikes were fast. (Below right) One experimental fairing that not only worked and looked trick, but also finished, was mounted on Steve Baker's Yamaha Factory machine. According to Baker's tuner, Bob Work, the fairing "made quite a bit of difference" on the long straight at Yamaha's test track in Japan. Baker's bike also sported magnesium · triple clamps,magnesium sand-cast carbs, and plenty of titanium. Arch-rival Kenny Roberts' altered TZ750D had the fairing and carbs available, but not the triple clamps or titanium. (Right) This is Kel Carruthers, the star road racer turned tuner for Kenny Roberts. Kel's using a file to remove melted polyester · from Kenny's 250's front disc brake. How did the melted polyester get on the machine's front disc? Take a look at Kel's right knee~ Pressing in close to check fork action when Roberts pitted during practice, Kellet his right knee brush the hot disc, and his pants left a melted glob behind. 13
