Note: S&S recommends the use of adjustable pushrods to obtain the correct valve clearance required.
Note: S&S recommends roller rocker arms with cams that have a lift greater than 0.585".
Note: S&S does not recommend 1.745 ratio roller rocker arm sets for street motorcycles. These will increase stress on the cams, tappets, and pushrods. For this reason, they are recommended for racing only and not for street applications.
