Does anyone know where to get metric bungs? I know bung king sells some, but I don't want to simply buy an assortment. Also, why aren't metric bungs sold more? It seems pretty lazy to build a bike and go through all that trouble only to run standard bungs. After having a Jeep I do not want to have multiple fastener types on a vehicle if I can help it and it means more tools I will have to use to work on the bike.
