Idler Gear Set : Recommended Motor / Gearing?

[BloodClod]

Just received one of the new idler gear kits from Atomic Carbon. Seems like the smallest pinion that can be run is 25T - is that correct?

I'm wondering what kind of pinions and motor setups are recommended for this.

I'm primarily running on a small-medium technical dirt track which is generally medium-loose in grip.

Thanks.
