Overhauling The Cylinder Head Components - Ducati MONSTER 821 Workshop Manual

Overhauling the cylinder head components

Cylinder heads
Remove any carbon deposits from the combustion chamber and its ducts.
Remove any scale from the coolant ducts.
Check for cracking and inspect the sealing surfaces for scoring, steps or other damage.
Check that the cylinder mating surfaces of the cylinder head are free of carbon deposits and scale. If this is
not the case, spread diamond lapping paste (6 to 12 micron thickness) on a reference surface and slide the
cylinder head on the surface as shown in the figure until a flat surface is obtained.
