As time permits, I have another small program in the works. It will be for LSR people, primarily. Not only will it have gearing ratio calculator (like the stand alone wheel speed calculator above), but will incorporate other utilities like a Density Altitude calculator, as well as a Torque caclulator (got to work the math out on this one). I'm open for other ideas to incorporate. As is with all my programs, they are all free for the taking. My shop work prevents me from spending much time programming. So, I do it on Sunday afternoons, or while on vacation. Sorry, to any of you who don't have or ride V-Twins. It's all I know about. Maybe some of it will be useful to you.
