My Droid says I'm getting 33.81 MPG average with a worst of 32.05 MPG and a best of 36.94 MPG.
My riding is 90% in town commuting to and from work (approx 5 miles one way)
Average distance between fillups is 150.60 with a worst of 141.00 and a best of 157.00
Average cost of fillup is $17.27 of an average cost per month of $23.02 ($.14/mile)
Average fillup is 4.42 US Gallons, so far 71.68 US Gallons YTD.
I do notice my fuel light comes on sooner since I swapped to a 17th front sprocket.
with the 17 tooth the speedo is closer to correct but the odo is off on the low side(ie you've gone farther than indicated) by about 8%+/-
