Just in case I decide to go with changing the speedometer gear, can someone confirm that Bill Hanlon is correct and my thinking is bass ackwards. If I’m traveling 40 mph but my speedometer is reading 30mph, I figured I would need to spin the cable 25% faster. To do that I would need a gear with 25% fewer teeth. Bill says I need to slow my cable down to increase the reading on my speedometer. I don’t understand how that works.
