1 or 2mA - probably just the clock keeping time.
With a 12AH (not sure whats on the 1000) battery, that will take 12,000 hours (500 days) to go completely flat but more like 2-3 months before you couldn't start the bike if you don't leave it on a trickle charger.
If its going flat after a week, it may suggest the battery is knackered.
