No need anymore those! I have changed stuff with one Finn guy: He want to put 900cc engine to his 750 Monster and he needeed those my 900 manifold and he bring to me 750 manifolds, what seems, to fit perfectly! I am now over 100% sure, that 750 and 900 Mikuni manifolds are totally different ones, as also Ducati ordering numbers are! Maybe this help someone...
