BSA B44 Shooting Star
The BSA B44 Shooting Star was a motorcycle made by BSA at their factory in Small Heath, Birmingham. Similar to the BSA C15 and sharing many of the same parts, the B44 had an uprated chassis. A weak point of the BSA 250 and most 350 unit singles were the big end bearing and timing side crank bush. The B44 had a double roller big end and a single lipped roller bearing supporting the drive side of the crank, with a ball bearing on the timing side. The timing side ball bearing was prone to failure, so one popular update was to replace it with an NUP305 removable flange roller bearing, thus strengthening the timing side and controlling the crankshaft end float. On the B50 single lip roller bearings were fitted on both sides of the crankshaft, with an outrigger ball bearing on the drive side to provide increased rigidity and end float control. History In 1965 an off-road motocross BSA B44 named the ‘’Victor’’ was launched at the Earls Court Show. Developed from scramblers use ...

Woodstock Festival
The Woodstock Music and Art Fair, commonly referred to as Woodstock, was a music festival held from August 15 to 18, 1969, on Max Yasgur's dairy farm in Bethel, New York, southwest of the town of Woodstock, New York, Woodstock. Billed as "an Age of Aquarius, Aquarian Exposition: 3 Days of Peace & Music" and alternatively referred to as the Woodstock Rock Festival, it attracted an audience of more than 460,000. Thirty-two acts performed outdoors despite overcast and sporadic rain. It was one of the largest music festivals in history and became synonymous with the counterculture of the 1960s. The festival has become widely regarded as a pivotal moment in popular music history, as well as a defining event for the Silent Generation, silent and Baby boomers, baby boomer generations. The event's significance was reinforced by Woodstock (film), a 1970 documentary film, an accompanying Woodstock: Music from the Original Soundtrack and More, soundtrack album, and a Woodstock (song), ...

BSA Motorcycles
BSA motorcycles were made by the Birmingham Small Arms Company Limited (BSA), which was a major British industrial combine, a group of businesses manufacturing military and sporting firearms; bicycles; motorcycles; cars; buses and bodies; steel; iron castings; hand, power, and machine tools; coal cleaning and handling plants; sintered metals; and hard chrome process. A government-organised rescue operation in 1973 led to the takeover of BSA-Triumph motorcycle operations by Norton-Villiers, later known as Norton Villiers Triumph. At its peak, BSA (including Triumph) was the largest motorcycle producer in the world. In the late 1950s and early 1960s poor management and failure to develop new products in the motorcycle division led to a dramatic decline of sales to its major USA market. The management had failed to appreciate the importance of the resurgent Japanese motorcycle industry, leading to problems for the entire BSA group. When Norton Villiers Triumph was liquidated in ...

Kick Start
Kick start is a method of starting an internal combustion engine (usually that of a motorcycle) by pushing a ratcheting lever with the rider's foot. Kick start mechanisms were almost universally a part of motorcycle engines before the mid-1970s, and were phased out of production over the next twenty years or so as electric starters became standard equipment. There are still some motorcycles produced that have both kick and electric starters. Many mopeds and scooters also carry both a kick start and an electric start, the former being useful in case the latter fails, as scooter and moped batteries tend to be smaller and, as a result, run down much faster than other forms of automotive batteries. Also, it is usually not possible to push start a moped or scooter with automatic transmission An automatic transmission (AT) or automatic gearbox is a multi-speed transmission (mechanics), transmission used in motor vehicles that does not require any input from the driver to chang ...

Compression Release
A compression release mechanism works to ease the starting of internal combustion engines by allowing them to rotate to starting speed without having to work against the compression of the pistons. It does this via either a release valve that is incorporated within the cylinder head that vents the cylinder pressure to the outside atmosphere until the engine has sufficient Angular momentum, momentum to overcome it, or by venting straight through one of the main valves. US patent US5375570 A of 1994 describes an automated compression release valve actuated by engine oil pressure. Motorcycles Early large displacement motorcycles with kick starters provided riders with a manual compression release while later models linked them to the kick start lever with a cable for automatic operation. The 2012 Ducati 1199, equipped with an electric starter, uses a compression release that is automatically activated at low engine speed by a centrifugal flyweight on each exhaust cam. This reduces th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiberglass
Fiberglass (American English) or fibreglass (English in the Commonwealth of Nations, Commonwealth English) is a common type of fibre-reinforced plastic, fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic Matrix (composite), matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than Carbon-fiber-reinforced polymers, carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins ...

Motocross
Motocross is a form of off-road motorcycle racing held on enclosed off-road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom. History Motocross first evolved in Britain from motorcycle trials competitions, such as the Auto-Cycle Clubs's first quarterly trial in 1909 and the Scottish Six Days Trial that began in 1912. When organisers dispensed with delicate balancing and strict scoring of trials in favour of a race to become the fastest rider to the finish, the activity became known as " hare scrambles", said to have originated in the phrase, "a rare old scramble" describing one such early race. Though known as scrambles racing (or just scrambles) in the United Kingdom, the sport grew in popularity and the competitions became known internationally as "motocross racing", by combining the French word for motorcycle, ''motocyclette'', into a blend with "cross country". The first known scramble race in the world took place in Camberley, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
