As some may know, my bike key is on a soft koala keyring and lives inside my glove (left or right, he's ambidextrous) inside my helmet when not in use. He's ridden there safely for years. Today I was carrying a lot of other crap, so the helmet was at all sorts of angles and I thought he'd fallen out. Looked everywhere, couldn't find him. Somewhat panicked, I then thought I might have left the key in the bike. I had, and the good news is that it was still there at the end of the day. The bad news is that it was in the 'On' position. Must have got distracted... hey, there are a *lot* of cute girls on campus! Battery was dead flat - so flat the bike wouldn't start in second down a long hill. I'll bus home, drive the cage in with tools, pull the battery out and take it home to charge overnight. My question is, might there be something worse than a flat battery. I'd heard that with bad luck leaving the ignition on could burn out the coil. I guess it's a testable question when I get back with a charged battery.
