S&S Cycle 97in. Big Bore Kit for 88in. Motors

The 97in. Big Bore kit for 88in. motors 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 cast iron 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, 4in. stroke, 97in. displacement, 9.7:1 compression ratio with stock heads (9.3:1 compression ratio with S&S 89cc heads or 10.7:1 with S&S 79cc heads).

Kits include cylinders, pistons, rings and gaskets (head, base and exhaust).

Black or silver powder-coat finish.

Made in the USA.
