To get a measurement that accurate you must have some big *** calipers!

Heck no. I'm not gonna use a calculator for this! I'm setting up an Excel spreadsheet. So all I have to do is input my MPH, and it'll tell me what my RPM's are. I'm planning on rigging up a 17" HP laptop to my handlebars. And with my voice recognition input, I'll just speak my MPH, and it'll automatically show me my RPM's. Just seems easier and more cost efficient than installing a tach.

I don't run a speedo or a tach, but when I did I found 2000 rpm in 2nd was 20 MPH (school zone) 3000 in 5th is 70mph, Only 2 I cared about.

And to think that for over 40 years I've just been doing all this by the seat of my pants...
