So stock is 12*42,13*45 or A*B, C*D

To calculate the ratio, B/A multiplied by D/C=gear reduction ratio

So for example, Polini 18*39 primary gears would be:
39/18*45/13=7.5:1 gear reduction.

Well, don't always count on it. Read my response to motormike about * puppy (maddog) and see why.

:confused: You have 8.4:1 primary gears?

I would bet you have stock primary gears and 8.44:1 secondary gears.
