Most all of the cable driven speedometer are calibrated at 60 mph, 1000 rpm of the cable is 60 miles per hour. Here is a good link to really check yours. https://www.hotrodhotline.com/calibrating-speedometer#.V9vrrjtT5TcTrans gears are a easy to change, but you still need to know how far off it is at 60. | | |
