S&S Cycle 910-0206 S&S Cycle 106in. Big Bore Kit - Black Powder-Coat 910-0206

The 106in. Big Bore kit yields excellent results with stock cylinder heads
Feature the largest bore (3.927in.) that can safely be used in a cylinder with stock spigot diameter
Even though stock cylinders can be bored to fit the 3.927in. pistons, the included S&S cylinders feature a much stronger liner to stand up to the added power
Easy installation: no need to bore or split existing cases, just swap the cylinders
Specifications: 3.927in. bore, 4 3/8in. stroke, 106in. displacement, 10:1 compression ratio with stock heads (9.7:1 compression ratio with S&S 89cc heads)
Kits include cylinders, pistons, rings and gaskets (head, base and exhaust)
Black or silver powder-coat finish
Made in the USA
