Anyplace to get info on what gear and number of teeth I need with my gears and tires size?
Thanks, Ron :unitedstates:

I checked my speedo with a GPS and used the following formula for a new gear. Add 1 tooth for every 5 to 7 MPH slow the speedo is or subtract 1 tooth for every 5 to 7 MPH over the speedo is. at 50MPH my sons GPS and my speedo matched. He could not believe that loose formula would work that good.

I haven't actually tried using it yet, but I found this formula online a while back, and saved it for future reference.
Formula
(Trans. Drive Gear) X (Rear Axle Ratio) X (Tire Rev. per Mile) /1000
Example
((7 Tooth Gear) X (3.27 Ratio) X (815 TRPM))/ 1000 = 18.655
Hope it helps.
Thanks for the replys Guys. See what I can do.
