Dragg-on Posted November 9, 2003 Report Share Posted November 9, 2003 Im hearing all sorts of good stuff about +4mm rods, that they give a bunch of torque. my first question is ... I have a stock length crank , what must I do to have a +4 crank? Quote Link to comment Share on other sites More sharing options...
PassionRE Posted November 9, 2003 Report Share Posted November 9, 2003 The +4 everyone is talking about is 4mm increased stroke length with 5mm longer rods. It's also available with standard rod length but most everyone prefers the longer rod version. These cranks assembly's are built by Wiesco and are available through many outlets and atv shops for less than $500. Mods to your cylinders and/or head are required to extract full potential in horsepower. The end result is bottom end that simply cant be duplicated by stock cranks and if ported correctly will rev to the moon as well with no lag in any area of the rpm range....Jim Quote Link to comment Share on other sites More sharing options...
