S&S 89 Inch 1984-1999 Big Twin Stroker Kit – Made To Order

This stock bore stroker kit for 1984-1999 Harley-Davidson® Evolution® big twin models has been the basis for an S&S Hot Set Up Kit® in the past. Now it is available as a made to order kit that allows you to configure the kit to your specifications.

By increasing the stroke of the 80 inch Harley-Davidson® Evolution® big twin engine from 4-1/4 to 4-5/8 inch the displacement is increased to 89 cubic inches. Stock, S&S Super Stock® or performance replacement heads can be used with this configuration, depending on which pistons are purchased with the stroker flywheels. 89 inch strokers can be installed in carbureted or fuel injected engines. Note that recalibration of the fuel injection system is required. No special machine work is required to install this kit other than a simple crankcase clearance operation and normal piston fitting. An 89 inch stroker kit makes a perfect stepping stone to a 96 inch engine in the future, because S&S 3-5/8 inch big bore cylinders can be added without rebalancing the flywheels. In fact, these flywheels are identical to the ones used in 96 inch S&S engines and Sidewinder® Kits.

The S&S Hot Set Up Kit® has long been the industries first and foremost complete performance solution for a specific application. Each kit contained everything you need to get the job done. Now we have made it even better. Made to order kits allow you to choose as much or as little as you like to suit your performance goals and what you already have.
