I re-geared my Falco last week. I went from a 2.56 (16 up front, 41 in back) to a 2.8 (15 in the front, 42 in back) ratio. I was expecting my speedo to be way off. I verified it by being paced by my wifes Volvo at 15, 25, 30, 40, 55, 65, and 75 mph (I know her car is reading the correct speed). At any given speed I was no more than 2 mph off. As far as I can tell, the speed is not read off the front wheel, so I was expecting an error. Does anyone have any insight as to why this did not occur? Was my speedo in error before the change and I just happened to correct it (this seems unlikely). Hmmmm....
