The Cometic complete gasket kit for 2002–2004 Yamaha SX Viper (70mm bore) supplies the full set of engine gaskets for a top-end rebuild; the head gasket is not included. Cometic relies on in-house dynamometers and engine assembly rooms to validate fit and function, and their gaskets are tested on street, track and dyno shakedowns to ensure reliable sealing under demanding conditions.
