The fork drain screws are 5 mm in diameter, necessitating a sealing washer made to fit a 5 mm fastener. Originally, Moto Guzzi fit a fiber washer in this location. 5 mm fiber washers seem difficult to obtain these days, and I've had trouble getting aluminum crush washers to seal properly. Therefore, my preference is to use a metal/rubber pressure sealing washer. McMaster-Carr part number 93786A100 works great.
