Valve guides and seats are important parts of a motorbike's valve mechanism. The valve guides are usually made of bronze or hardened steel and serve to guide and support the valve stems. The valve seats, on the other hand, are the surfaces on which the valves rest and are sealed.
Over time, valve guides and seats may need to be replaced due to wear or damage. If the valve guides have too much play or the valve seats are damaged, this can lead to loss of power and irregular combustion. Regular inspection and, if necessary, replacement of worn or damaged valve guides and seats is important to ensure the reliability and longevity of the motorbike.
Valve guides and seats must also be carefully lubricated and cooled to prevent overheating or damage. Insufficient lubrication or cooling can cause the valve guides and seats to overheat, resulting in deformation or cracking. Proper lubrication and cooling are therefore critical for optimum performance and longevity of the valve mechanism in the engine.
