  2. Yamaha XV1900A - Wikipedia

    en.wikipedia.org/wiki/Yamaha_XV1900A

    The Yamaha XV1900A cruiser was developed to exploit the large displacement end of the market for large cruisers.Yamaha had a well established range of big "Star" cruisers which went up to the Wild Star 1600 cc but there was a need to redesign the engine to meet anticipated exhaust emissions regulations and the opportunity to update the styling, which had remained largely unchanged for a decade.

  3. Valve guide - Wikipedia

    en.wikipedia.org/wiki/Valve_guide

    In the 1980s, many U.S. production engine remanufacturers began reaming valve guides, rather than replacing them, as part of their remanufacturing process. They found that by reaming all the valve guides in a head to one standard size (typically 0.008 in. diametrically oversized), and installing remanufactured engine valves having stems that are also oversized, a typical engine head can be ...

    Roadliner can mean: Daimler Roadliner - a single deck bus or coach chassis built by Daimler between 1962 and 1972 Yamaha XV1900A motorcycle, also called Star Roadliner (US), Star Stratoliner (US) or Yamaha Midnight Star (UK)

  5. Cylinder head porting - Wikipedia

    en.wikipedia.org/wiki/Cylinder_head_porting

    Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve their air flow. Cylinder heads, as manufactured, are usually suboptimal for racing applications due to being designed for maximum durability. Ports can be modified for maximum power, minimum fuel consumption, or a ...

  6. Automobile engine replacement - Wikipedia

    en.wikipedia.org/wiki/Automobile_engine_replacement

    Long block - a short block, with mounted and gasketed cylinder head, valves and camshaft; Crate engine - a new or remanufactured engine, considered to be equivalent to a new engine. [3] Parts include more than a long block, including intake manifold, and carburetor or fuel injection system, oil pan, valve covers, and perhaps an alternator

  7. Idle air control actuator - Wikipedia

    en.wikipedia.org/wiki/Idle_air_control_actuator

    An idle air control actuator or idle air control valve (IAC actuator/valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed . [1] In carburetted vehicles a similar device known as an idle speed control actuator is used.

  8. Two-stroke power valve system - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_power_valve_system

    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 primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...

  9. Desmodromic valve - Wikipedia

    en.wikipedia.org/wiki/Desmodromic_valve

    A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional ...
