Here is a great gearing calculator.

Before changing to the 19t, I took note of precise rpm at speed. Now I am truly perplexed. 70mph was 4200rpm and now 70mph is 4200rpm! Math wise I should have seen about a 5% difference, a drop of about 200rpm. I am totally weirded out on this one. I noticed a 19t stamp on the new sprocket, but by God I'm pullin' that cover off and counting them. If I was sent an 18 with a 19 stamp, NewBonneville is going to hear about it!

Ossaman.. the speedo is not accurate. The speedo drive is in the trans.. not at the wheel. As such if you tooth up or down you wont indicate any differently. It'll only be apparent when keeping up with traffic !
