TKO 600 Second Gen Speedometer Calibrate
Running the .64 TKO 600 5 speed with a 3.42 rear gear 25.7" tire. All of the online calculators for speedo gears say to use a 19 tooth driven gear. This makes my speedo read approx 87 mph at 2000 rpm, supposed to be reading 71mph. Tried a 21 tooth. Read 80 mph at 2000 rpm. Still off. I see they make a 23 tooth but say it is limited use. What are you running to get yours right? Could it be my tacometer is off also?
