RupertB,
After searching for the specifics that you are looking for, I would think that they are all specific to model, make, and gearing. The speed in each gear will change with different sprocket sizes and ratios, as well as tire sizes used. My suggestion, is to make a drawing in Corel Graphics or in Adobe Illustrator, and make the overlay you want, and then print it on a laser printer onto overhead projector clear sheets that are made for a printer. If you have a color laser, all the better, and you could change fonts, sizes, and colors to suit your need.
And truthfully, I did not see a single gauge overlay that was for what you want to do. I am thinking if nobody here can point you in the right direction to find them, if they still exist, and for your particular gearing and final ratio, you would have to create your own.
