Well i got my custom fuel tank back the other week from the fabricators. It was done as a favour for me so for casting nothing its a nice bit of kit if a little heavy weighing in at about 1.2kg empty. Made of stainless steel with a standard Jerry can nozzle slightly modded so a small pad lock can be put on if required and has a capacity of 6lt's. Fits snugly where the 2nd exhaust should go using the existing exhaust mounts and two simple wing nuts. You can fill it up while on the bike but obviously have to remove it to use which take literally 1 minute. Anyway thought i would share it with the forum for ideas sake:
