Growing up in the '50s, my friends and I were the more adventurous types. Baseball and football were our games of passion.
We built model airplanes and learned how to fly them-and crash them. We also rode and worked on our Schwinn bicycles a bunch. The local bicycle store just happened to sell Whizzer motorbikes, and up the street from them was a Cushman dealer selling Cushman motor scooters. And a few miles down the road in the next town was a long-time Harley-Davidson dealer where bikers would congregate every Friday night before their weekly ride. As kids, we often made a point of riding our bicycles to the Harley dealer on Friday night to check out the Knuckle and Panhead "dressers" with big seats, fringed saddle bags, megaphoned exhausts, and blue-dot taillights. When buying parts at our local Schwinn dealer, we also enjoyed admiring the new Whizzer motorbikes, especially the kick-start Sportsman model-the one without pedals. Most of my friends and I planned to get a motor scooter as soon as we turned 14. At that time, a 14-year-old could get a scooter license as long as the motor wasn't over five horsepower.

It seemed to take forever, but eventually we all turned 14 and got a scooter-Cushman, Whizzer, Lambretta, Mustang, Vespa, Zundapp...the choices were plentiful. The Mustangs were 10 horsepower, but some of us got one anyway. I eventually ended up getting a Cushman and then a Mustang. The older brother of my close friend Marty owned a beautiful custom two-tone metallic green Whizzer Sportsman, but then he got into hot rodding his '32 Ford 3-window coupe, so he gave the Whizzer to his brother, Marty.
Just as my friends and I worked on our Schwinn bicycles, we worked on our scooters, boring them out, upping compression, gutting mufflers, installing big Amal carbs, and testing long odd-looking tuned intake manifolds.
Here's the author's street...
Here's the author's street Sportster in early '68 with a 74ci engine, Dytch big-bore cylinders, 12:1 compression pistons, S&S 4-5/8 inch stroke flywheels, bored Linkert DC carb, Sifton cams, magneto ignition, and kick-start.
One morning I stopped by my friend's house to see if he wanted to go riding. I found Danny in his garage on his knees with his father's acetylene torches fired up. He wanted a hot cam, so he was brazing his Cushman's camshaft lobes. He finished off his piece of mechanical genius by using a bench grinder to finish-shape the cam lobes. By evening, Danny had his Cushman back together and we went riding. After a couple of hours, Danny's engine quit running, and I towed him home with a piece of rope. When he dismantled the engine, the cam lobes were completely worn away. Surprise! Fourteen-year-olds don't know that brass is soft and cam lobes must be heat-treated steel.
