[Shotimes] Engine Break In (WAS: Interesting...porting the intake)

[James F. Ryan III]

Yeah, that's a good article on break-in, Marc (with a "c") from Georgia had
posted that link about a year ago.

Getting back to the original thread topic - if you scroll almost to the
bottom of the web page there's a box that says, "Intake Porting - SMALLER
ports gain 7% more power".  Just to the left of that he says he'll debunk
common misconceptions about port enlarging & polishing, and cam timing.
Perhaps this only applies to the relatively short induction systems of
motorcycle engines this guy works on, but I'm still very interested in
Bruce's results.
