Riding a medium pace out in the CA desert, I can get ~100 miles safely. At Cal City, my friend of mine with a stock tank and same jetting went ~70 before running out within sight of the trucks. Stock is 2.1 gal. It seems to be workimg out to ~33 - 35 mile per gallon in the desert. Now, riding at LPNF, he would go on reserve at about the 45-50 mile mark. Considerable less. get bigger tank.
