  • Before installation, thoroughly clean all mating surfaces to remove old gasket material, carbon deposits and oil residue — any contamination will compromise the seal.
  • Inspect the cylinder head and barrel mating surfaces for warping or scoring with a straight edge before fitting new gaskets; do not install on a damaged surface.
  • Do not reuse old gaskets; replace the entire set during each top end rebuild to ensure consistent sealing.
  • Apply torque to cylinder head bolts in the manufacturer-specified sequence and to the correct torque values listed in the KTM or Husqvarna service manual for your model year — never estimate torque by feel.
  • Allow sealant (if specified by the service manual for any non-paper joints) to cure for the manufacturer's stated period before starting the engine.
  • After reassembly, perform a leak-down or compression test to verify correct sealing before returning the bike to service.
  • Bed-in the engine gently for the first few minutes of running after a top end rebuild — avoid high loads or maximum revs immediately.
  • Store unused gaskets in their original packaging in a cool, dry location away from direct sunlight, fuels and solvents, which can degrade gasket materials.
