Magazine Tuning Article
British Mag "Classic Motorcycle Mechanics" sept 2013 edition has tuned port timing info used in UK when RD350 was the hot production racing tool of early 80's. This is the first of 2 articles by Stan Stephens who turned out some fast bikes in his day. Don't know if anyone has anything better but it looks like a good reliable place to start from.
