Tassinari VForce III

Hi mates,

I've just recive a new reed valve block Tassinari VForce 3 Art.nr. 40312100 and it doesn't fit my MMW2 manifold. MMW top side has a square part that goes inside the original RD350 and it doesn't fit the rounded top hole of Tassinari. The only solution I can see is mill MMW2 manifold.

Do anybody know something about this subject?.

Regards.
