Agree 100%, alarms are far more trouble than they're worth, i got the dealer to remove the alarm from my gen1 before I picked it up. Chain to a ground anchor at home, and, if you're really worried, a Tracker gives a better chance of getting the bike back and the toe-rags caught. It takes seconds to sling a bike into the back of a van, and nobody but you cares if the alarm is going or not!
FWIW, I'd get a dealer to remove the alarm, then any problems are theirs, not yours.
