I love working on the bikes as much, and probably more even, than riding them.
It's like bringing something back to life! It's a nice feeling of accomplishment and pride when you stand back and see what the hours of work have done. I'm sure everyone on this site feels the same way after all the time and energy that's put into a bike that they can look at and get a big smile.
That's why the Before and After photos are so important. Sometimes you don't realize the Train Wreck you brought home ever looked that bad!
