Re: Gear Ratio?

According to the figures in the previous post (my body being a 2211), I should be looking at a 3.90:1 gear ratio. I have a 3 speed overdrive transmission.

Tonight I marked my driveshaft with chalk, and did the same with my LR wheel. I rotated the wheel and counted both the turns of the wheel and the driveshaft.

The wheel turned twenty times to forty-two on the driveshaft, to bring both marks back to the starting point.

Now I would have expected to find something close to a 4:1 (3.9:1 to be exact) ratio. This is only 2:1.

What am I doing wrong? Maybe I should have turned the driveshaft itself?
