S&S Cycle 97" Big Bore Kit For Harley Big Twin
You know the saying - "There's no replacement for displacement!"
Features:
- Kit yields excellent results with stock cylinder heads
- Features the largest bore (3.927") that can safely be used in a cylinder with stock spigot diameter
- 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
- Easy installation: no need to bore or split existing cases, just swap the cylinders
- Specifications: 3.927" bore, 4" stroke, 97" displacement, 9.7:1 compression ratio with stock heads
- Kits include cylinders, pistons, rings and gaskets (head, base and exhaust)
- Black or silver powder-coat finish
- Increased fin area for better heat dissipation
- Valve pocket recessed in S&S pistons are enlarged for oversize valves and higher lift cams
- Maintains stock engine height and stock piston weight
- Made in the USA
