Top Gasket Kit Yamaha YZ 250 Cometic
Cometic gaskets are made in the USA from high quality materials. A lot of the gaskets in these kits are manufactured from AFM Material. AFM is foam like and will not stick to the engine case making replacement quick and easy, with a much greater chance of being able to reuse the gasket, which is handy if you are at the track and have to sort an issue. The AFM gaskets have an aluminum core that gives the gasket strength for a superior seal and prevents the gasket from weeping or crawling out. All gasket kits come complete with all gaskets and orings and crush washers needed for the job.
