If you know that you were about 65 mph at 3400 rpm's, you can use a calculator probably located in some of these sites to calculate your gear ratio! As long as it is 1.1 in 3rd gear you should be able to convert your mph/rpm's and tire size to figure your gear ratio.Someone help me on this???
I have a spreadsheet I worked up that calculates all that - with a 27 inch tire, 65mph @ 3,400 RPMs would put you at about a 2.89, although there's slip, tire distortion and all that to enter into it, but you'll at least be in the ball park.
