S&S 106" Big Bore Kit Silver (910-0202)

S&S - 106 Inch BIG BORE KIT

• Kits include cylinders, pistons, rings and gaskets (head, base and exhaust).
• Made in the U.S.A.
• The 106 inch Big Bore kit yields excellent results with stock cylinder heads.
• Easy installation: no need to bore or split existing cases, just swap the cylinders.
• Even though stock cylinders can be bored to fit the 3.927 pistons, the included S&S cylinders feature a much stronger liner to stand up to the added power.
• Specifications: 3.927 bore, 43/8 stroke, 106ci displacement, 10:1 compression ratio with stock heads (9.7:1 compression ratio with S&S 89cc heads).
• Feature the largest bore (3.927 in) that can safely be used in a cylinder with stock spigot diameter.

NOTE: This project requires a skilled technician. It is the responsibility of the person assembling the parts to check all clearances and assembly specifications.
