Diaphragm platelets for the horizontal two-valve diaphragm of the LML 5 channel motors.
Its original steel diaphragm platelets tend to have an unsightly throttle behaviour around 3500 rpm. Replacing them with the carbon plates will fix this and increase the overall performance over the whole rpm range. In addition, in case of a defect (breakage) carbon plates are completely unproblematic for the engine internals (crankshaft/cylinder) compared to steel plates.
FAZIT: Should be used with every LML engine!
