Review HONDA Rear Cylinder Head Assy. Engine Valve Train fits MAGNA VF700 VF700C 700 1986

The Honda 12020-mk3-770 rear cylinder head engine valve train is a crucial component of the 1986 VF700 Magna, 700 FT86, and VF700C motorcycles. This valve train is responsible for managing the intake and exhaust flow of gases into and out of the engine's combustion chamber.

The valve train consists of several parts working in unison to ensure optimal engine performance. These parts include the intake and exhaust valves, camshafts, lifters, and pushrods. The intake valves allow the fuel-air mixture to enter the combustion chamber during the intake stroke, while the exhaust valves facilitate the expulsion of burnt gases during the exhaust stroke.

The camshafts are responsible for opening and closing the intake and exhaust valves at the correct timing. They do this through the use of lobes on their surface that push against the valve stems, opening the valves as they rotate. The lifters, which are located at the bottom of the camshaft, provide a hydraulic push to the camshaft lobes, allowing the valves to open and close smoothly.

The pushrods are used to transfer the force from the camshaft to the rocker arms, which in turn open and close the valves. The intake and exhaust valves are operated by separate pushrods, with the intake pushrods being longer to accommodate the greater distance between the camshaft and the intake valves.

This Honda rear cylinder head engine valve train is known for its durability and reliability. However, like any mechanical component, it can wear out over time due to use and environmental factors. Regular maintenance, such as valve adjustments and valve clearance checks, is essential to ensure the longevity and optimal performance of this critical engine component.

In summary, the Honda 12020-mk3-770 rear cylinder head engine valve train is a vital part of the 1986 VF700 Magna, 700 FT86, and VF700C motorcycles. It consists of several parts, including the intake and exhaust valves, camshafts, lifters, and pushrods, all working together to manage the intake and exhaust flow of gases into and out of the engine's combustion chamber. Regular maintenance is necessary to ensure the longevity and optimal performance of this critical engine component.
