4 mm
aluminium

for tuned engines Product description
A base
gasket surface spacer
, or
packing-plate
, sits between the reed-valve and the cylinder. The use of this 5mm thick aluminium packing-plate from
TD-CUSTOMS
fully opens the boost-port. Without its help the frame surrounding the reed-valve petals obstructs the function of the boost-port.

Do not forget to order a new MMW reed-valve block.
