There is one more important point. The series II has a different gear box:
new gear ratios: 3.87, 2.08, 1.36, 1.00 and 0.76
Final drive ratio: 3.73
old gear ratios: 4.23, 2.52, 1.67, 1.22 and 1.00
Final drive ratio: 3.08

I have never understood gear ratios. Would someone be kind enough to explain as I find this topic interesting given my current predicament.
