The Cometic head gasket for 1977–1979 Suzuki GS750 is a 69mm bore .043 replacement engineered to seal the combustion chamber while requiring less clamp load. It spreads load evenly across the sealing area to reduce bore distortion and does not require sealants or re-torque. Install it during head work or rebuilds to recover reliable compression and consistent engine operation.
