Taper throttle kit includes a Race specification CNC cylinder head
with 34mm inlet & 28.50 exhaust racing valves.
have improved the specification of some of the components, particularly
in the valve train area to cope with this high revving engine specification,
in particular we have designed a special valve made from 2 materials
to give strength & flexibility on the valve head, yet increases
strength & durability in the valve stem to cope with the extra
loads from the high lift cams & rpm.
