Reference: 31004-G01 — Brand: CYLINDER WORKS
Top-end gasket designed for Big Bore Cylinder Works cylinders, intended for Cross riders replacing their original cylinder. This gasket ensures a seal between the cylinder head and the cylinder when installing a big bore kit. Made to be compatible with Cylinder Works top-end kits, it integrates into engine preparation operations without surprises.
Ideal during a rebuild or big bore conversion: replace the gasket each time the cylinder head is removed to ensure proper alignment and sealing. Particularly suitable for owners of KX 250 F (models listed below) fitting their bike with a Cylinder Works cylinder.
Prioritise a clean installation: clean the gasket surfaces, follow the manufacturer's torque specifications, and replace other gaskets if necessary for an engine ready to tackle the tracks.
