They do this so the dirt at the bottom of the tank doesn't get sucked into the tank.
This is something I had heard many times. In doing so I had asked myself how the dirt got there. The fuel delivery pumps have filters and I dang sure didn't put it in there myself. A couple of years ago I switched the peanut tank on my Sporty out for the larger 4.5 gallon tank and while doing so wanted to see if I could find this dirt they spoke of. As it turned out that tank was extremely clean after 16,000 miles of riding. It did however tell me there was actually a bit more than a pint of fuel left in the tank after I had drained it at the switchover valve.
