I don't know if I posted this spreed sheet before but it allows you to play around with difference formats for changing gears and the resulting speeds. You can enter your own information to see what results you will get by changing gears and \or sprockets. Hope this is of help to those considering making changes. You will have to unzip the files. Excel format.

 

I made this one from a pdf another forum member posted. I liked the layout and expanded the chart to compare changes to the stock set up. You can put in several changes and scroll them under the stock for a compare.
The green shaded area has the gear ratios for a 2007 Ultra. The yellow are the variables you can plug in and the other shades show the values for the RPM you plug in and the MPH you plug in.
