I'm thinking of changing the tank on my s4 to something that has a bigger capacity and looks more cafe racerish if that makes sense and was wondering if anybody has done this. I presume what ever tank I use has to have the fuel pump in the tank like it is at the moment so I was thinking something like a 916 sp tank or such like any ideas or pointers would be appreciated.
I'm not aware of any OEM tank that is larger and will fit without extensive reconstruction.
You could go with an external pump, but that doesn't seem to be a common configuration on high pressure setups.
