Take that Gurtner off your AV7 and toss it on the shelf or trash. This Malossi intake lets you install the Dellorto SHA carburetor on your AV7 or AV88 Motobecane.
19mm OD and 15mm ID.
One some Motobecane cylinders, you may have to file the top edge of the intake or a cooling fin down to fit. Easy and quick fix.
