• The valves supplied in the race kit are used to increase compression ratio, by
having a flat face on the combustion chamber side. They are made from the
same material and have the same mass as the standard valves.
1. Remove the existing inlet and exhaust
valves following the procedure detailed
in section 3 of the Daytona 675 service
manual.
2. The valve seat widths on the race kit
valves are narrower than the standard
valves, therefore the bottom angle
o
(120 ) of the cylinder head valve seats
must be modified to ensure the seat on
the head matches the seat on the valve.
