I left my petcock open over night and didn't realize until I tried to start the bike in the morning. It didn't fire or turn over. When i realized what I had done I blew the gas out of the cylinders and started it up. Now it sounds like it has a miss fire on the number 3 cylinder. I did some looking around online and found some people saying that it is possible to bend piston rods in this situation. Is that true? how likely is that?
