Bill Blue tm33 mileage

I recently installed a mikuni tm33 pumper carb on my klr250.
I've only run one tank of gas through it so far.
The acceleration is better than stock. I have not really tried to wheelie it yet, but it does feel possible, where I could not wheelie it with the stock cv carb.
I use the bike to commute. I've got a cycleracks rack with a top box.
I was getting 60-70 mpg on my commute with the stock carb. The first tank of gas with the pumper gave me 40.7 mpg! I was not expecting such a dramatic drop, and coasted into the gas station this morning having run it empty on reserve.
I like the acceleration with the new carb but am not sure if I can live with the milage. With the stock tank being less than 3 gallons I'm going to have to fill the tank every day for my 37 mile one way commute. I don't think there are any aftermarket tank options which significantly increase the tank size. Am I wrong?
