The solenoid moves pretty smartly but is moving a very small mass against a fairly weak spring. The current it is drawing either means the electromagnet is total overkill - more powerful than it needs to be, or it is very inefficient - perhaps with only a few windings. The truth is probably a bit of both. As I noted, I intend to try installing a resistor in-series with the solenoid to reduce the current it draws. This is not a big deal on the GS but on my airhead RT, I need to save every watt I possibly can.
Ideally, I'd have a clever circuit to cut the current to minimum once the solenoid has moved - but that would be adding potential failure points again.
