Fuel Tank Filling

[Fj.itis]

I agree noel, the bikes tanks just aren't big enough and its this reason im thinking about modifying my spare tank to take a few extra litres. Plus it should tie in better with the frame width, as my bike has no fairings and the frame sticks out around the tank.

I wonder how much of an extra sump i can make at the fuel tap area? Will have no issues draining the tank then even with the inline filter.
