Now your odometer will read about 7% short of actual. When you calculate your fuel mileage, multiply it by 1.07 to get a comparable number to your previous gearing.
I put on a 43-tooth rear when I changed my chain and sprockets at 18800 miles. The problem is that winter showed up and then I quit the job that had me riding a bunch. I was not able to make a good comparison of mileage between the two gearing configurations.
