Cool. Everything you gave me is super helpful. I also found a great RPM calculator.  The last four fields are the only ones you need for a motorcycle and there is one flaw with the calculations: you have to plug in the tire RADIUS where is says to put in the tire hight.

After playing around with that and checking out everything you said I decided to go with an 18/43 if I even change it at all.
