I'm aware of the motor oil sump, motor oil filter, and transmission sump drain plugs under the Ryker, but I noticed when under there that there were 3 other plugs that I couldn't identify. Two of them were a similar set to the motor oil pair; A big plug that takes an allen key, and a smaller plug next to it. The other was a vertical, hex head plug close to the horizontal transmission drain plug. Does anyone know what these are?
