Seeing that magnetoman has been outed by someone else I think people who are reading this tome should know who he is:

The good Dr. has one of the most extensive annotated motorcycle and related mechanical engineering libraries in the World. Not only has he read them all, but collected a huge database allowing him to research subjects quickly.

While his approach follows a strict academic model that some would consider overkill, he is not satisfied to have the skill to do something, but to also understand the underlying physics.
Now, if I could get Dr. Falco, Kevin Cameron and Rob Tuluie together with a tape recorder or better yet write for Vintage Bike...
