The function of the valve stem seal
Valve stem seals are installed in the valve guides and slide to control valve stem lubrication. Too little oil can cause stem and guide wear. Too much oil can increase oil consumption and cause carbon deposits, which can lead to valve seat damage and premature valve wear. At the same time, if the valve stem seal is damaged, it will also increase the fuel consumption.NNK cd70 cg125 Single/ Double ring motorcycle valve stem seal
