Caution

  •  the valve seat contact area must be inspected after each cut.

  •  The titanium valves are coated with an oxidized membrane treatment to resist wear but the membrane tend to removed if lapped after valve seat servicing.

after servicing the valve seats, be sure to check the valve clearance after the cylinder head has been reinstalled. Refer to valve clearance inspection and adjustment in section 0b .
