I enjoy wrenching on my own bikes. At times I have learned how to do something by learning how not to do it several times. I am not a mechanic and will take the bikes to a ship when needed. However I have learned that the more I do the more I learn and am able to do. A shop Manuel is a big help as well. I just have to remember my limitations so I don't end up spending more on repairs to fix my repairs. Like Clint Eastwood said, "A man must know his limitations."
