I built an E-Kart but I am finding it hard to find and figure out what gear ratio that will give me a top end of 60-70mph. The only sprocket I am finding for my motor is for a roller 40 or 50 chains. I wanted to do 15 teeth sprocket (motor) and 25 teeth on the axle.
The problem is finding a 428 sprocket with 15 teeth to fit on my motor... Do anyone know where i can find this sprocket or have a better idea...????
