Intake manifold Moto Guzzi Serie Grossa carburetor Dell'Orto PHM 40

Intake manifold kit suitable for all Moto Guzzi Serie Grossa models with stock Dell'Orto PHM 40 carburetors: this is a modification kit of the original manifolds produced in vibration-resistant plastic. It is also possible to use this intake manifold kit to install Dell'Orto PHM 40 carburetors on Moto Guzzi models with stock Dell'Orto VHB carburetors: however, it will be necessary to use M6-M8 studs (code 300017268) to attach the manifolds to the head. The thread present on the cylinder heads is M8 while the supplied bolts have M6 thread. Alternatively, it is also possible to remove the brass bushing present on the manifold mounting flange and grind the manifold to make room for the head of the new M8 bolts, but this is strongly discouraged: the reduction bushings are used to give the correct rigidity to the mounting of the manifolds on the heads preventing vibrations from causing damage.

Intake manifold kit features:

• plastic model: direct attachment without rubber sleeve
• compatible carburetors: Dell'Orto PHM 40
• complete set for single carburetor
• contents: mounting clamp, M6 bolts, o-ring and gasket
