SUZUKI DRZ400 Vacuum port nipple


This is the needed part when converting to a Keihin FCR or FCR-MX carburetor on your DR-Z400.
In order for OEM the petcock on the DRZ400 bikes to operate correctly, it needs vacuum. The OEM carburetor pulls vacuum from the top cap port but FCR carburetors don't have a port like that and you don't want to drill the carburetor to create a access port.  By mounting this part you create a port on cylinder head to pull vacuum from and operate the petcock and its a 2 minute task.  This part his not needed you have gravity fed fuel petcock.
