At idle rpm the generator won't produce full output.

Do you think I can get higher amps?10Ah is the capacity of the battery, I think Darrsi was referring to Cold Cranking Amps. CCA is a measure of the battery's ability to deliver high currents for short periods at low temperature.
If you want an analogy: Ah is how big a petrol tank is, CCA is the bore of the petrol tap at the bottom.
Not that high CCA is automatically better. If you want to start the bike when the temperature is -20ºC then it's probably a good choice, but the tricks employed to get high CCA also make the plates more prone to buckling so the battery may not last as long.
