    I have been listening to your podcasts the last couple of weeks and so far have really enjoyed them, looking forward to next monday. I have a question: what is the website you found that has the ability to find what bikes a specific part was used. This info would be awesome. Anyways keep up the good work. I am working on a 1969 cd175, next project is a cl350 with a blown piston.
