S&S Cycle 910-0205 97 Big Bore Kit For 99-06 Harley Twin Cam 88 Black 60302
99-06 Harley Twin Cam S&S 97 Black Big Bore Cylinder Piston Kit 60302. Largest bore that we feel can safely be used in a cylinder with a stock spigot diameter. Bolt-on 9 to 10 cubic inches - cylinders do not require crankcase machining to install. Increased fin area for better heat dissipation. Forged coated pistons are compatible with stock or S&S Super Stock.
Valve pocket recessed in S&S pistons are enlarged for oversize valves and higher lift cams. 11 fins and full fin pattern on cam side closely resembles OEM shape.
S&S logo and part numbers are less conspicuous. Silver powder coat or wrinkle black powder coat cylinder finish color matches Harley-Davidson. S&S Wrinkle Black Powder Coat Finished Bore Kit Fits Big Twin models 1999/2006 88" to 97" Displacement.
