VALVE STEM SEALS CENTAURO - set of 4 (manufacturer reference: P650903/4): parts designed for the refurbishment of cylinder heads for Quad, Cross, and Roadster. These seals, designed for intake, ensure a tight seal around the valve stem and limit the intrusion of oil into the combustion chamber, an essential role for a clean engine adjustment and smooth operation.
Manufactured to meet the demands of regular maintenance, these Centauro seals are suitable for preparations and repairs on 2- and 4-stroke engines used both off-road and on the road. They are suitable for interventions on the cylinder head during the replacement of guides or piston rings and integrate easily into a service kit.
Examples of models where these seals may be relevant: HONDA CRF 110 F (JE02), APRILIA SXV 450 (2017), HONDA CRF 50 F (AE04). For a clean and durable replacement, always check the valve stem diameter and manufacturer specifications before installation.
