NARAKU - Valve Stem Seals (Set of 2)
Manufacturer part number: NK101.45
Set of 2 NARAKU valve stem seals, designed for 4-stroke cylinder heads. Manufactured to OEM quality standards by Taiwanese and Japanese manufacturers, these seals ensure tightness around the valve stems to limit oil ingress into the combustion chamber. Replacing these seals is a common step when disassembling the cylinder head to prevent abnormal oil consumption and deposits on the seats and spark plugs.
Workshop tips: when changing, clean guides and seats, check for wear on the valve stem, and replace seals in pairs for reliable sealing. These seals are part of the essential maintenance components to control oil consumption and maintain the health of the upper engine.
