I can't remember the name of the racer but it seems just as he was leading the Isle of Man TT to the finish he sucked a nice piece of gravel into his engine and kablooey he was done. That pretty much sums it up, although I do admit velocity stacks sure are pretty (and they can be fitted with filters of a sort).

A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. Herm Albright (1876 - 1944)
