                                                                    Gearing Formulas:  Ratio x MPH   X 336 = RPM     OR        Ratio =   Ratio x Tire Dia.

                                                                                                              Tire Dia.                                                                    MPH x 336

                                                                    Final Drive: (# of Teeth Top Gear) + (# of Teeth Bottom Gear) x R&P = Final Drive

                                                                                Gear RPM Change:           RPM     

                                                                                                                          Gear Ratio      X   New Ratio = New RPM
