Detection of valve seat runout of motorcycle engine

The cylinder head material of the motorcycle engine is mostly aluminum alloy. Because the aluminum alloy material is soft, and the valve seat is working at high temperature, the wear is serious. Therefore, the valve seat is usually made of a good material (alloy cast iron, austenitic steel, etc.) separately embedded in the cylinder head, and the taper surface generally adopts a taper angle of 45° or 30°. The amount of runout of the cone is an important factor affecting the performance of the valve seal. Now we have a brief introduction to the structure, principle and usage of a set of special inspection tools.

SAD (Seasonal Affective Disorder)
Many people eat and sleep slightly more in winter and dislike the dark mornings and short days. This is known as 'winter blues'.Others have more severe symptoms which such as sleep problems, withdrawal, overeating, depression, anxiety and lethargy. These often lead to difficulties at home, work and in relationships. This is a recognised problem known as Seasonal Affective Disorder(SAD).
