Note:
N1, N2, N3,& N4 Pulleys are the same for RH and LH Threading.
The .96 LH setup requires a 65 tooth belt.
Calculation: Pitch = (14/11)*(11*N3)/(N2*N4)
Pulleys are numbered consecutively through drive train and belt B12
couples N1 to N2; belt B34 couples N3 to N4.
B12 is belt length running between N1 and N2; Similarly for B34
