Difference between revisions of "Tom Sifton"

An almost iconic tuner of [[Harley]]s. Tom Sifton started out as a sub-dealer for Dudley Perkins in San Francisco in 1929 and became a full dealer in San Jose in 1933.  But he increasingly spent his time tuning Harley-Davidsons for competition. With detailed work on the porting and valves, he was able to make the unpromising 45 into a race winner, but just how he did it remained a secret from fellow tuners and even from the factory's racing department. Spanning the years from Sam Arena to Joe Leonard, Sifton went on making [[side-valve]] Harleys go faster for decades, also working his magic on the [[Harley-Davidson WR|WR]] racer in the late 1940s and the [[Harley-Davidson KR|KR]] in the 1950s and 1960s. In addition, he is known for his own design of "Sifton cams."
