Yamaha RD350LC
The Yamaha RD350LC was a two-stroke motorcycle produced by Yamaha between 1980 and 1983. Although it immediately succeeded the larger RD400, the RD350LC was powered by a smaller 347cc parallel twin two-stroke engine which actually had the same bore and stroke as the older RD350 (64 x 54mm). However, Yamaha added liquid cooling and made other modifications in porting and exhaust to comply with ever-tightening emissions regulations. The RD350LC was later replaced by the RZ350 / RD350LC II / RD350 YPVS in 1983, but the LC(1) was also sold in that year alongside the new bike. The RD350LC was aimed at the European market alongside the smaller capacity Yamaha RD250LC. The 1980 to 1982 350 cc models were codenamed 4L0 and are affectionately known as ''Elsie''.Henshaw 2001, p. 414. This model was not officially sold in the US but was available in neighbouring Canada. Yamaha debuted their breakthrough YPVS power valve system that revolutionized the two-stroke engine in the RD350 YPVS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha Motor Corporation
is a Japanese multinational manufacturer of motorcycles, marine products such as boats and outboard motors, and other motorized products.

Yamaha RD400
The RD400 is a two-stroke air cooled six-speed motorcycle produced by Yamaha from 1976 until 1979. It evolved directly from the Yamaha RD350 The 350 evolved into the RD400C in 1976, the "D" and "E" in '77–'78 and the final model, the white 1979 RD400F. (The model year for the first RD400, which was sold in the U.S. in the summer of 1975, was 1976.) The RD series was discontinued due to new emissions rules in the late 70's and eventually all road motorcycles were 4-stroke engines and did not burn oil with the fuel mixture to lubricate the pistons. The RD400 came with a unique self-cancelling light system that measured wheel rotations after the indicator lights were enabled. Also, for convenience, the RD did not require pre-mix fuel in the tank since it came with a 2-stroke oil pump which delivered the appropriate amount of oil when the throttle was engaged. The brakes were single disc front and rear. It could complete a standing quarter-mile in 14.01 seconds. The RD400C was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha RZ350
The Yamaha RZ350 is a two-stroke motorcycle produced by Japanese motorcycle manufacturer Yamaha between 1983 and 1996. Available in the US from 1983-1985, Canada until 1990 and Brazil until 1996. The RZ was the final evolution of the popular and well-known series of RD Yamaha motorcycles, and as such is also known as the RD350LC II or RD350 YPVS. It is powered by a twin-carburetted reed valve inducted, liquid-cooled, 347cc parallel-twin two-stroke engine, with a bore and stroke of 64mm x 54mm. It was the first RD series from Yamaha to receive the 'YPVS' Yamaha Power Valve System. A different version of this motor with no YPVS was also used in the Yamaha Banshee 350 ATV, which was produced for some markets until 2012. It is also raced extensively in Vintage racing leagues, as well as its own racing leagues, often dubbed "RZ cups" in Europe and Canada. Versions There were several models, the 1985 RZ350F, 1986-92 RZ350F2,N,NF, and the 1992-5 RZ350RR which was produced in Braz ...

Yamaha RD350
The RD350 is a two-stroke motorcycle produced by Yamaha from 1973 to 1975. It evolved directly from the piston port (pre-reed valve intake tract), front drum-braked, five-speed Yamaha 350 cc "R5". The engine is an air-cooled, parallel twin, six-speed (in some markets, such as the UK, the first model was sold in five-speed form), reed valve-equipped intake tract two-stroke engine. The bike is usually referred to as a sport bike. All models were equipped with "Autolube" automatic oil injection, relieving the user from the need to mix gasoline and two-stroke oil. Rim sizes are 18" WM2 (1.85") front and 18" WM3 (2.15") rear, both being of chromed, wire spoked steel construction. In the UK, rim sizes were 1.60 front and 1.85 rear. Brakes are: single front disc brake and a rear drum brake, a combination described by ''Cycle Magazine'' as the best in its class. The frame dimensions of the street ''350'' are very similar to the Yamaha TZ 250 and TZ 350 series factory road race bikes ...

Parallel Twin
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 ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the power an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. The formula is: : \text = \text \times \frac \times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stroke Power Valve System
{{Unreferenced, date=February 2018 The two-stroke power valve system is an improvement to a conventional two-stroke engine that gives a high power output over a wider RPM range. Operation of a two-stroke engine A ''stroke'' is the action of a piston travelling the full length of its cylinder. In a two-stroke engine, one of the two strokes combines the intake stroke and the compression stroke, while the other stroke combines the combustion stroke and the exhaust stroke. As the piston travels upward in the cylinder, it creates low pressure area in the crankcase; this draws fresh air and atomized fuel from the carburetor through a hole in the cylinder wall or directly into the crankcase. As the piston continues travelling upward, transfer ports and the exhaust ports are closed off, thus trapping the combustible mixture in the combustion chamber. As the piston reaches the top of the cylinder, the mixture in the cylinder is compressed to the point of ignition. The second stroke beg ...
