Editing Harry Ricardo

An English [[cylinder-head]] specialist, whose pioneering work on four-valve combustion chambers inspired generations of engineers.  At [[Joe Petrali]]'s suggestion, he was brought in to develop [[Harley-Davidson]]'s eight-valve racer for 1915. [[Walter Davidson]] refused at first, faced with the cost of Ricardo's steamship ticket and his fee, but relented when Petrali reminded him that $25,000 had already been spent on the eight-valve. Ricardo duly worked his magic and the bike was transformed into a race winner. Less successful was the [[side-valve]] Model A 21ci (350cc) single that [[Harry Ricardo]] had had a hand in and which had a tendency to seize if ridden hard for any length of time.
