  • Do not use a hone on engines with carbon impregnated cylinder liners like the Honda Prelude Si or 1997 Acura NSX 3.2L.
  • Use only a rigid hone. Do not use a “bottle brush” or spring type hone as they don’t maintain straightness and concentricity.
  • Use a 400 – 600 grit fine finishing stone to achieve a quality finish.
  • Always use honing oil and maintain wetness of cylinder wall and stones.
  • Scrub cylinder walls using a mixture of hot water and laundry detergent and a stiff bristle brush after honing.
