How To Build A Custom Chopper?
People learned how to build custom choppers in the United States after World War II. They were created as a result of unsatisfied potential motorcycle customers, who came back from the war missing the simple structure of European made motorcycles. Once back, American soldiers found the opportunity to improve the local made motorcycles by making them more efficient and personalized, with a tight budget like the one used in this article.
Materials You'll Need:
- Old English bicycle
- Two-stroke, one cylinder engine kit: Includes carburetor, gas filter, air filter, gas line, power chain, engine block, gas tank, electric switch, exhaust pipe, big Gear, spacers, stock bolts and nuts, small black pin
- Phillips screwdriver
- Bicycle wrenches sized 8mm to 22mm
- Allen wrench
- Working table with safety harness
- Place the bicycle frame on a working table and hold it firmly against the surface with a safety harness.
- Open the box where the engine kit package is stored. Your carburetor should be on top of the engine and the air filter mounted on it. If it isn't, turn the box upside down and check there is no oil leaking from it. Keep your 14mm wrench in your right pocket. It will come handy.
- Mount the engine block placing the washers between the “V” shape frame over the crank and pedals. The engine should fit accurately against the bicycle frame. The chain should hang down towards the exhaust pipe.
- Hold the engine in place with your left hand, and use your right hand to reach the 14mm wrench in your pocket and adjust the bolts on the washers, until the engine is firmly secured against the frame. Check the air filter on top of the carburetor and secure the hose at the bottom, with a screwdriver.
- Adjust the gas tank ten inches from the saddle on the topside of the frame. It should be right over the carburetor, with the gas cap facing the roof as in any motorcycle. Secure it tightly with washers and bolts. Install the gas line that hangs from the gas tank through the top line of the frame and connect it with the gasoline filter that matches the carburetor. Secure the gas line to the frame with black tape.
- Install the big gear on the left side of the back wheel with a spacer on each side, and secure the original pin with the original bolts. Secure the chain that was hanging from the engine around the rear gear, with the black small pin packed in the engine kit. Use pliers to secure the pin. It should be tight as in any bike.
- Use the Allen wrench to adjust the electric switch and the right handle bar on the right side of the front end of the frame. This will be used to accelerate. It should be at least six inches away from the gas line and the gas tank. Match the black cable from the electric switch with the black tab at the left side of the engine and the red cable with the red tab on the opposite side. Stick some black tape around the electric joints and to the frame to avoid loose cables that could entangle.
- Start the engine by pushing your bike and accelerating when turning the new installed right handle simultaneously. Once the engine is running, you will be ready to ride your bike.
- Wear a motorcycle helmet when riding your bike and boots to protect your ankles. The original bicycle brakes might not be that effective on the full throttle, so you should avoid competitive racing. Check the oil deposit before using the motorcycle, and be certain about the gasoline and oil mix used as fuel.
