Cometic copper head gasket 0.043" for 1973–1975 Yamaha RD350 with a 66mm bore requires less clamp load and conforms load distribution across the sealing area. It reduces the need for sealants or re-torque and helps limit bore distortion, making it a tailored replacement for older RD350 engines undergoing maintenance or restoration work.
