crack of near valve seat. Check for the warp of
the cylinder head with a square and filler
gauge.

CYLINDER HEAD DISASSEMBLY
Remove the cylinder head from cylinder.
Remove the cylinder head gasket, dowel pin
and cam chain guide.
Remove the valve stem seals and valve spring
seals, remove the carbon deposits from the
combustion chamber.
To prevent the loss of tension, do not compress
the valve springs more than necessary to
remove the cotters.
Mark all parts during disassembly so they can
be placed back in their original locations.
Avoid damaging the gasket surfaces.
NOTE
Remove the valve spring cotter, retainer, spring
and valve using the valve spring compressor.
