Lambretta Inlet manifold, large block, rubber mounted, Dellorto PHBL, Mikuni TMX 24mm, MB


This manifold will let you fit a 25mm (22/24mm) PHBL Dellortos, 24mm Mikuni carburetors onto a 200cc type cast cylinder (Factory, RT, Rapido, Mugello or Original barrel).

It comes with a stainless steel long bolt to replace the long inlet stud, otherwise it is very hard to fit the manifold without dropping the engine.

One of many Inlet manifolds designed by us MB, Ideal for a cut down, chopper or no panelled type Scooter where you can use a remote filter as the inlet manifold is shaped for flow into the intet manifolds. Not ideal for full body Scooters apart from Series 1/2 types.

NOTE; if using a Li type head cowl the air scoop will need shaping, or use a GP type head cowl or even better a MB Carbon head cowl.

Thank you for the very prompt delivery.

The manifold itself is excellent quality, despite it looking like it would bolt straight on it fouled one of the cooling fins on the barrel so needed filing down, it would have been nice if the inlet was about 5mm longer but it is now fitted and working great
