Here you can see the oil tank, there is a tube that goes up and through the fuel tank. Fuel tank has two caps, one for oil one for fuel. More of Dave's great work shows in the foot peg setup fro the driver. I am going up to see Dave next month and hope that Big Twin is still there so I can take some more pictures. I'll be picking up the AEE Kit Bike that Dave has helped me with. Hopefully I'll be able to finish it next year!
