The vacuum flowed through the switch to a vacuum solenoid (such as a heat riser, used to restrict exhaust allowing the engine to heat up faster). When the coolant heated to operating temperature the vacuum switch closed off the port (port S on the vacuum switch) turning off the vacuum to the heat riser. The result is to clear the exhaust ...
Current Honda general-purpose engines are air-cooled 4-stroke gasoline engines but 2-stroke, Diesel, water-cooled engines were also manufactured in the past. The current engine range provide from 1 to 22 hp (0.7 to 16.5 kW). More than 5 million general-purpose engines were manufactured by Honda in 2009.
Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intervening carburetor or throttle body leading to the intake manifold. It is a ...
In 1984, the bike was introduced with Honda's Radial Four Valve Combustion Chamber (RFVC). [citation needed] It has a 110 kg (240 lb) claimed dry weight, [1] and a 36-inch seat height (96–04). Honda claims the engine produces 28 horsepower at 8000 rpm and 17 ft-lb feet of torque. The 1996–2004 versions of the XR250R had 10.6 inches of ...
Its purpose is to restrict the flow of air, thereby enriching the fuel-air mixture while starting the engine. Depending on engine design and application, the valve can be activated manually by the operator of the engine (via a lever or pull handle) or automatically by a temperature -sensitive mechanism called an automatic choke.
The Honda CBX250RS is a motorcycle first sold by Honda in May 1983 in Japan as their new 250cc sports bike with a view to replacing the popular CB250RS. The engine was based on the XR series with particular links to the XR350 bottom end, including a six-speed gearbox and the same oil pump.
The Honda CMX250, or Rebel 250 or Honda Peronist, is a 234 cc (14.3 cu in) cruiser-style motorcycle made by Honda on and off since 1985. It uses the same 234 cc (14.3 cu in) straight-twin engine as the Honda Nighthawk 250 standard .
The Honda CB250N and CB400N Super Dream are motorcycles manufactured by the Honda Motor Company from 1978 to 1986. The successor to the short lived Dream model, it had a series of revisions including a six-speed transmission and what Honda termed as European styling [6] which resembled the CB750F and CB900F.
