Can I Overfill My Tank?
#11
There is an air gap in tanks so that you do not over fill. This is for expansion of the gas because things expand and contract when its temp changes. Go fill your tank to the brim ontop that hot motor, and park it in the sun. so it expands more. Do you ever wonder why a gas can has a pop off top because it has to release the pressure. Your gas tank does not have a pop off valve, only the gasket on the cap. The air in the tank can compress when the fuel expands and contract the liquid ful cannot compress so some thing has to give. If you dont have air how much pressure can that gasket take before the gas is push past it and onto your bike. You may get by 100 time but what happens if it does overflow onto your hot engine.
Something else to think about, have you ever seen a gallon of compressed gasoline catch on fire much less 6 gallons.

If I'm traveling any at all I "burp" it (shake the handlebars), and refill it at least 3 times to get all the fuel in I can. Never had any problem.
