Default Re: Speed calculator

I am thinking when entering the motor rpm that what we are really using is the clutch sproket rpm which is about 1/4 the motor rpm???
and if 6000-7000 is about safe high motor rpm ,then the sproket rpm is 1500-1700 rpm to enter into the calculator (this seemed to make the mph come out like I hear on the threads all the time)
I am talking about a china girl
