How can that be? For every 2.12 revolutions of the driveshaft the wheels rotate once. I don't see how you get around that fact. The ratio is the ratio of the input to the output, or in this case 2.12:1 . Believe me, I wish it were 4.1 but wishing or multiplying by 2 won't make it so. If it were 4.1:1 I would have turned the driveshaft over 4.1 times and the wheel would have rotated once. That's not what happened. That's why I said someone would probably think I was a moron or a lunatic.

Ok, so I am a moron. It's 4.3:1 . Helpful hint for the impaired such as myself-if the result seems to be about half of what is expected, rotate BOTH wheels simultaneously and count the corresponding number of rotations of the driveshaft.
