I also hooked a spring to the engine speed bar and another part of the engine. I drilled a hole through a nut, slid the wire through the hole, and then - once I had the wire as tight as I wanted it - screwed the bolt on the nut to hold everything in place. To hold the wire end in place, I made a wire swivel stop (you could buy one at a hardware store if you wanted to). Then I slid the other cable end into the clamp on the side of the engine and through the hole in the metal bar that controls the engine speed. I put the cable end that had a ball on it into the throttle grip on the minibike’s right handlebar. The only job left was to hook up the throttle and throttle cable. Once that was done, I hooked the chain up to the sprocket on the clutch and to the other sprocket on the minibike. (I put the clutch on so its chain sprocket was on the inside.) I tightened the key in place with an Allen wrench. To do this, I first lined up the key slot on the shaft with the key on the clutch. Next, I put the centrifugal clutch on the engine shaft. Then came the fun part - putting them all together!įirst I bolted the engine to the frame with strong bolts, nuts, and lock washers. Now I had the main parts for my minibike, and I’d spent only $60. In a hardware store, I found a new centrifugal clutch that would do. It had to have the same size hole as my engine shaft, as well as gear teeth that would fit my chain. There was just one thing left that I needed: a centrifugal clutch (that’s the kind of automatic clutch that engages when you accelerate the engine). It had a size #35 chain, brakes, tires, chain sprocket, throttle grip, and throttle cable. After trying junkyards and other places, I finally found one in a lawn mower repair shop. Then I started the hard job - looking for a minibike frame. The best-priced engine I found was a 3-horsepower Tecumseh with a 5/8 inch side shaft. I tried hardware stores and also shops that repaired lawn mowers and small engines. The first thing I did was to start looking for a used engine with a side shaft. He said I could try, but he doubted I could really do it. One day while I was working with my dad, I got the idea of making my own minibike. But most new minibikes cost from $260 to $450. Like many other kids, I wanted a minibike I could scoot around on. Address inquiries to Mother’s Children, MOTHER EARTH NEWS, Hendersonville, NC.
