Ok, I am r-e-a-l-l-y s-l-o-w working on projects
. I never finished the cruise control install last year, but I going to finish it this weekend.
I figured out the pulses per mile for this project:
Rear Tire = BT56 (24.9 inch diameter according to BFG's website)
Pulse ratio = 12.6 pulses/rear tire revolution
Pulses per mile = 10206
Of course, this doesn't take into account the change in diameter when in motion with a rider, so I looked at what the pulse/mile would be if the diameter was smaller: 23.9 inch diameter = 10632 pulses/mile
The universal cruise control has dip switches that allow you to tell the cruise control how many pulses/mile it sees. There is a finite number of settings and the 10,000 rev/mile setting will have to do.
I have the unit installed, and all I need to due this weekend is finish the wiring and test it out. If anyone would like details, I have pic's I can post or e-mail.
