Motocycle Mechanics
Motorcycles are not only a source of entertainment; they can also be a source of transportation and income if someone wanted to make a career of them. Motorcycles are used in many aspects of life. Children, as well as adults, ride motorcycles on trails, open fields and on motocross tracks. They may race, jump or do stunts with the motorcycle. Groups, such as Harley Davidson owners, get together to ride for charity events. Because motorcycles are so cheap to ride, they are great source of transportation. A motorcycle can get 60 to 70 miles per gallon whereas a small Toyota Camry can get 18 to 23 miles per gallon. Industries such as farming, delivery, entertainment, aviation and even the military are known for their use of motorcycles within their operations. Due to the popularity of the motorcycle there has been an emergence of self-taught mechanics. Not all these mechanics can keep up with the new technologies and advancements. “The impact of new technology on the motorcycle industry has been dramatic” (Motorcycle 1). Electronic ignitions, fuel systems, drive trains, and turbocharged engines are just a few areas of advancement. Well-trained technicians are needed and sought after. Job opport
hospitalized as a result of a motorcycle accident. 4,700 of them die. Many others will be crippled for life. In some countries the death rate for motorcyclists is up to nine times higher less expensive to manufacture and repair. The piston, cylinder, and crankcase serve dual roles in developing power” (“Motorcycle Mechanics” 74). The engine is made up of two parts: a top end and bottom end. The top end contains the cylinder, the cylinder head, piston, the piston rings and the wrist pin. The bottom end contains the crankshaft, the crankcase, the seals, the bearings and bushings. The cylinder’s job is to seal and guide the piston so that it can react to the power of the expanding gases. There are a series of passageways called ports that move gases in and out of the engine. According to David, former motorcycle mechanic, the cylinder head is the area where the gas and oxygen mix on the down stroke, but on the upstroke it is compressed and ignited by the spark plug to produce a mini explosion, which creates power. The cylinder head vibrates constantly and is subject to high temperatures. During a rebuilding job, the cylinder must be inspected thoroughly to make sure there is no warping. If warped, sanding it with emery paper can repair it. The main job of the piston is to hold the ring. The ring must be tight in order to get a good tight seal in the cylinder. If the seal is tight there will be good compression. Lack of compression means a lack of power, preventing the engine from working efficiently. The piston and the piston pin need to be checked for scratches and cleanliness during a rebuild. If any dirt or deposits are left on the piston or the ring it will cause the rings to stick and lead to power loss. So it is very important to take the time to thoroughly check and clean the piston and the piston pin. When replacing a piston, make sure there is enough clearance in the cylinder. Motorcycle books can be purchased with exact measurements and clearance values in them. If there is not enough clearance the piston will shake (seizure) resulting in noise, damage to the cylinder wall and loss of power. their construction and lowers their weight. This makes the two-stroke engine lighter, simpler and
