As far as the 2 amp draw: I did not measure during actual engine load (i.e., bike accelerating), only reving the engine setting in the shop. It could go up with actual load, but I don't know why. It makes sense to go up with RPM since there are more sparks/second.
Know very little about the workings of the Ninja's engine

Fuel injection would have to work harder under load, but the actual ignition could use less power if the fuel reduces resistance in the spark gap.
