Re: speedometer gear
Frost:
Not quite that simple. Depends on what rear end you have and what "drive gear" you have inside your transmission along with the height of your tires. I just fiddled with mine. First step is to find out how far off your current set up is. You need to either use a GPS or a speedometer app on a smart phone to find your actual speed compared to the readout on your speedometer. Then you can see how far off your speedometer is. Next step is to pull out the "driven gear" that is inside where the speedo cable hooks to the tranny and count the number of teeth on the gear you have. Finally, you can order a new "driven gear" with more or less teeth to correct the speedo readout. The info I read says that more teeth on "driven gear" slow down speedo and less teeth increase speedo. Change of one tooth adjusts the speedo by 5%.
For example, I found that my speedo was 15% too slow. So I pulled out my gear and found that it was green in color and had 22 teeth. I ordered a new 19 tooth gear to replace it. Three less teeth should increase speedo by 15%. I haven't put the new one in yet, but that is my plan.
Gears are available online at speedo shops, Summit Racing, Ebay, etc.
Hope that helps.
