An 89" stroker kit makes aperfect stepping stone to a 96" engine in the future, because S&S 35⁄8" big bore cylinderscan be added without rebalancing the flywheels. In fact, these flywheels are identical tothe ones used in 96" S&S engines and Sidewinder® Kits.1984-1999 BIG TWINSParts forEvolution ®1984-1999Parts forSportster ® & Buell ®1986-2012Parts forVintage Engines1926-1984PERFORMANCEKITSFITMENT• 1984-'99 carbureted engines• 1995-'98 EFI enginesFEATURES AND BENEFITS• Stock, S&S Super Stock® or performance replacement heads can be used with thisconfiguration, depending on which pistons are purchased with the stroker flywheels.• 89" strokers can be installed in carbureted or fuel injected engines.

They offer the same compression ratio, but increasedstrength with a low noise, low silicon, forged material.S&S Super Stock cylinder heads do not have provision for the stock head temperature sensor. For this reason they are not compatible with fuel injected applications. Fuelinjected stroker engines must use stock cylinder heads or S&S performance replacement heads.
