Fomoco speedo gears are color coded so you can match your rear gears to your speedo. I believe each color is different by 1 gear tooth. If your speedo is slow compared to your actual speed you would step down( I believe, or visa versa!)) gear teeth to increase your speedo speed. I used to go to a junkyard that had some fords close to my year and grab a few different colored plastic gears.
