It depends on which electrical consumers you use. The simple equation is:
amps (needed) = watts divided by volts
Just add up the watts of all eletrical consumers (headlights, wipers, blower,
lamps, radio, etc.), divide this number by 12 (or better 13) and you'll get the
amps the dynamo/alternator should be able to generate at least, if you use all
these consumers at the same time. No need to add the watts of the starter
motor, as this is fed from the battery for obvious reasons.
The 25 amp generator is good for about 325 watts, while the 22 amp generator
will only serve 285 watts consumers. Consumers with the highest consume rate
are typically the headlights.

Thanks for all the responces so far. I like to share with the group when I
learn something new. I did learn that the BN1 puts out 22 max. cont. output
(amps) and the BN4 puts out 25 max. cont. output (amps). So there is a 3 amp
difference. Is this a big deal? I'm not sure, but would think so?
