I've put 5.9 gallons in her (in the states), and 21.7 liters in here in Germany. Never any signs of cutting out; even in leaning turns.
Always use mileage as indicator. Before mods, the light always came on at 150-160. After mods it comes on 135-145. I know I still have more than 2 gallons left at that point to I have an easy 50 miles by throttle ripping standards!
