Kawasaki Z750 Twin
The Kawasaki KZ750B twin is a twin-cylinder, touring motorcycle announced in 1975 and manufactured from 1976 to 1979. It was based on the smaller Kawasaki KZ400 introduced in 1975. The air cooled engine shared similar engine design with the KZ400 having chain-driven twin dynamic balancer shafts. The valve seats were hardened to allow use of low-grade fuel. The machine was engineered to have a wide power band and smooth torque curve.Kawasaki 76 range, ''New Motorcycling Monthly'' (Editor John Thorpe), IPC Magazines TI Media (formerly International Publishing Company, IPC Magazines Ltd, IPC Media and Time Inc.

Kawasaki Motorcycles
Kawasaki motorcycles are manufactured by the Motorcycle & Engine division of Kawasaki Heavy Industries. History Kawasaki Aircraft initially manufactured motorcycles under the Meguro name, having bought an ailing motorcycle manufacturer, Meguro Manufacturing with whom they had been in partnership. This eventually became Kawasaki Motor Sales. Some early motorcycles display an emblem with "Kawasaki Aircraft" on the fuel tank. During 1962, Kawasaki engineers were developing a four-stroke engine for small cars. Then some of the engineers transferred to the Meguro factory to work on the Meguro K1 and the SG, a single cylinder 250 cc OHV. In 1963, Kawasaki and Meguro merged to form Kawasaki Motorcycle Co.,Ltd. Kawasaki motorcycles from 1962 through 1967 used an emblem which can be described as a flag within a wing. Work continued on the Meguro K1, a copy of the BSA A7 500 cc vertical twin. and on the Kawasaki W1. The K2 was exported to the U.S. for a test in respons ...

Air-cooled
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Four-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Straight-two Engine
A straight-twin engine, also known as an inline-twin, vertical-twin, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft. Straight-twin engines are primarily used in motorcycles; other uses include automobiles, marine vessels, snowmobiles, Jet Skis, all-terrain vehicles, tractors and ultralight aircraft. Various different crankshaft configurations have been used for straight-twin engines, with the most common being 360 degrees, 180 degrees and 270 degrees. Terminology The straight-twin layout is also referred to as "parallel-twin", "vertical-twin" and "inline-twin". Some of these terms originally had specific meanings relating to the crankshaft angle or engine orientation, however they are often also used interchangeably. In the United Kingdom, the term "parallel-twin" is traditionally used for engines with a crankshaft angle of 360 degrees, since the two pistons are in the same direction (i.e. parallel to each o ...

The Motor Cycle (magazine)
''The Motor Cycle'' was one of the first British magazines about motorcycles. Launched by Iliffe and Sons Ltd in 1903, its blue cover led to it being called "The Blue 'un" to help distinguish it from its rival publication ''Motor Cycling (magazine), Motor Cycling'', which, using a green background colour, was known as "The Green 'un". Many issues carried the strapline "Circulated throughout the World". The covers eventually used a variety of different background colours after 1962, with a name-change to ''Motor Cycle''. Features Noted for detailed road tests of contemporary motorcycles and articles on readers' bikes, the magazine had regular features, including "Current Chat" and "Letters to the Editor" where many of the key issues relating to British motorcycling of the day were debated. The contributors often signed their pieces with pseudonyms such as ''Torrens'' (Arthur Bourne, one of the Editors) and the famous ''Ixion'' (Canon B.H. Davies). Recent history From 1962, ...

Kawasaki KZ400
The Kawasaki KZ400/Z400 is a street motorcycle that was produced by Kawasaki between 1974 and 1984. The 398cc displacement of the twin cylinder engine was increased to 443cc for the KZ440/Z440. The later KZ400-J used a 399cc four cylinder engine. Twins The original Kawasaki KZ400 was a 398 cc twin cylinder motorcycle produced from 1974 to 1984. The engine had twin balancer shafts to reduce vibration, one in front of the crankshaft and one to the rear, both moving in the opposite direction to the rotating crankshaft. An emission control system recycled "blow-by" gases. The manufacturers advertised it as a "most practical all-round machine". Later models displaced 443 cc. The KZ400 was built at plants in Akashi, Japan and Lincoln, Nebraska. The Lincoln plant (built in 1974) made Kawasaki the first foreign motorcycle manufacturer to operate a plant in the United States. The KZ400 outsold Honda in the 400 cc twins market through the 1970s. These motorcycles were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touring Motorcycle
A touring motorcycle is a type of motorcycle designed for touring. Although almost any motorcycle can be used for this purpose, manufacturers have developed specific models designed to address the particular needs of these riders. Touring motorcycles commonly have large displacement fairings and windshields that offer a high degree of weather and wind protection, large-capacity fuel tanks for long ranges between fill-ups, engines with a great deal of low-end horsepower, and a more relaxed, upright seating position than sport bikes. Particularly in the US, touring motorcycles may be given names such as ''bagger'', ''full bagger'', ''full dresser'', ''full dress tourer'', or ''dresser''. These monikers (often used disparagingly or jocularly) originally applied to cruisers with full sets of saddlebags or panniers such as Harley-Davidsons; but these terms may now refer to any touring motorcycle. Full-dress tourers Full-dress touring motorcycles are generally characterized by ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engine Balance
Engine balance refers to how the forces (resulting from combustion or rotating/reciprocating components) are balanced within an internal combustion engine or steam engine. The most commonly used terms are ''primary balance'' and ''secondary balance''. ''First-order balance'' and ''second-order balance'' are also used. Unbalanced forces within the engine can lead to vibrations. Causes of imbalance Although some components within the engine (such as the connecting rods) have complex motions, all motions can be separated into reciprocating and rotating components, which assists in the analysis of imbalances. Using the example of an inline engine (where the pistons are vertical), the main reciprocating motions are: * Pistons moving upwards/downwards * Connecting rods moving upwards/downwards * Connecting rods moving left/right as they rotate around the crankshaft, however the lateral vibrations caused by these movements are much smaller than the up–down vibrations caused by ...

Valve Seat
The valve seat in an internal combustion gasoline or diesel engine is the surface against which an intake or an exhaust valve rests during the portion of the engine operating cycle when that valve is closed. The valve seat is a critical component of an engine in that if it is improperly positioned, oriented, or formed during manufacture, valve leakage will occur which will adversely affect the engine compression ratio and therefore the engine efficiency, performance (engine power and engine torque), exhaust emissions, and engine life. Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position, and then machining a conical-section surface into the valve seat that will mate with a corresponding conical section of the corresponding valve. Generally two conical-section surfaces, one with a wider cone angle and one with a narrowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octane Rating
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the fue ...
