I had my girlfriend on the back of my first bike, 71 Honda CB500, which I had been riding at least 300 or 400 miles a week for 6 years to work and for fun. All of a sudden it died pulling away from a light. I screwed around with a bunch of stuff, and couldn't get it started. We walked a mile or two through the ghetto at night and called my mom from a payphone. When she got there i had to lift the bike straight up into the back of the pickup, and laid it on it's side. When we got home, I lifted it out of the truck and saw that the petcock was turned to off. I always rode that bike until it started cutting out, then switched to reserve and had 30 miles to find a gas station. When it cut out with the old lady on the back, I for some unknown reason turned the fuel to OFF instead of RESERVE like i had thousands of times before. So i switched to reserve and it started right up. I was so excited to have my baby back that i decided to celebrate by attempting a wheely in front of the house in front of the family. They were very impressed by the shower of sparks shooting out of the transmission, and on the other side the kick starter was spinning wildly and smashing into my leg. When the bike stopped The whole thing engine and trans were locked up solid. It never ran again. It sat on the side of the house for years while i drove a van instead of riding. I got tired of looking at it and one day ran it over while i was parking the van. I went back and forth over it a few times and then got out to take a look with my brother. The bike was sure run over but it had broken one of the blinkers on the van. That pissed me off even more. My brother and I chopped the bike up with an axe into more manageable pieces, then threw it all into the back of the van and dumped it out in the desert. All this from a brain fart. Remember to check the easy and obvious stuff first.
