Most of my friends think I'm anal about tire pressure and suspension adjustment and lubing pivot points. A few years ago a group met at our house to leave for a motorcycle event about 200 miles away. Before leaving, I insisted everyone check their tire pressure and had my compressor tank filled and ready for action. I recall one guy on a Honda Shadow that showed less than 12 lbs of air in the front and certainly under 20 in the rear! I told everyone, I don't mind stopping to help if you break down but if it's just plain negligence like that on your part you're on your own!
