Gearing Commander Gear Ratio and RPM Speeds
« on: September 16, 2023, 10:32:59 PM »
Hey all, trying to see if my entered data in the green "custom" line is correct for a stock 1977 CB750K. Not sure if the tire entry makes sense if I'm running a battlax rear tire thats 130/90/17 the circumference shows larger than the 18" rim/tire specs compared above in the stock and current lines? The 4th and 5th gear ratios were also adjusted to reflect a stock 1977 CB750K. 




Mainly just trying to figure out an accurate RPM to speed ratio since I'm running an aftermarket tach that detects pulses off the ignition coil and wanna see how accurate it is compared to the computations. Thanks!
