One of the Alsport factory race trikes was equipped with a Kohler free air 3 cylinder motor and huge expansion chambers and 3 flat slide carbs. Well they were at their test track with a professional driver getting ready to demonstrate this full blown RTS series machine to all the factory executives it was being built to race against the Dunecycles like yours.
Well they fired the machine up and the rider revved it up and nothing happened no clutch engagement and of course that brought out the shop mechanics and they couldn't fine any thing wrong , so they tried it again and when the top RPM hit the converter the trike did a back flip and just about killed that test driver and the executives gave that project the heave ho on the spot. How ever the motor got sold to a guy in Los Angeles and he put it on a Alsport. But never could get it working on the little speedway style track we used called Trogen Speedway. I built an absolute bare bones live axle trike with a McCulloch 101D engine with dual Alky carbs and a Horstman slipper wet clutch. The driver was Wayne Coppers and he was about 155 pounds soaking wet. That little trike regularly beat all comers even the big triple. That trike didn't even have a pad in the seat and was only 6 inches off the ground more like a 3 wheeled go kart. Those were the fun days of racing 2 and 3 nights a week all over Southern California places like Indian Dunes, Corona Raceway, Perris Raceway and of course Trogen. Big question how did so much fun not get captures on film not even a simple snap shot. Steve
