Cylinder Disassembly And Assembly - Suzuki GSF650A Service Manual

1D-46 Engine Mechanical:
CAUTION
!
• The valve seat contact area must be
inspected after each cut.
• Do not use lapping compound after the
final cut is made. The finished valve seat
should have a velvety smooth finish but
not a highly polished or shiny finish. This
will provide a soft surface for the final
seating of the valve which will occur
during the first few seconds of engine
operation.
NOTE
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 (Page 0B-6)".
