Why don't people think to do this? Everyone has heard the phrase "service manual" and "parts book" before some time in their life, even if it is for the washing machine in their pantry.

I knew a kid with a Honda 450 a few years ago and he wanted me to work on it for him for free. I may have helped him but he did not even want to try. His bike came with an excellent owner's manual that told you how to do everything short of re-machining the parts. I told him to read it from cover to cover and do what it said. Instead he took it to a shop that another "friend" of his worked at and paid to have it done. All he was interested in was posing around on the bike at coffee shops, he was not interested in learning mechanics, the history of the bike, it was just a trendy piece of jewelry for him to flash around.
