Springs only need to be done on the S&S 495 camsDave_D said:Did you have to change the springs or is the lift/duration tammer then others. How long did it take you to change them out.
I'd rather have the better curve than the higher number.kevinx01 said:The S3 cam is a decent cam in a mostly stock bike with an open intake. While it does not make real big numbers it creates a VERY good curve. With most open intakes you typically loose 7-8FtLb across the botom, and the lower overlap of the S3 gives you that back plus a couple more FtLb. Roll on passing in 6th from 55MPH becomes a real thing without downshift. Typical numbers tend to be around 97/105 with 90FtLb available just off idle
