Dellorto 36mm Carburettor right side

These carburettors are the later version of the Dellorto PHF as used on the Series 2 1000cc and RGS models, MotoGuzzi, Ducati etc. They will not fit directly onto the the early alloy Laverda manifolds.

It is important to note that standard Laverda 3 cylinder models have 32mm ports and the 750 SF models are often 34mm.

There are two popular methods of fitment onto Laverda.

1. Use the Rubber Moulded Manifold which bolt directly to the head without the insulating spacer These manifolds come in two sizes: 32mm Manifold  and 36mm Manilfold. Using these  manifolds may require porting of the head or the manifold to match the inside diameters.

2. Use the 32mm Alloy Manifold and Rubber Connector. Using these components requires the Alloy Manifold to be matched to the inlet port size of the head. It is possible to modify the existing Alloy Manifold on the 750 SF models to accept the Rubber connector.

Warning; Whenever the standard fitment is altered there will be other considerations and variations that need to be made. It is best to consult a professional engine performance engineer for advice to avoid costly damage to your engine.
