S&S Cycle 90-1106 99-05 BT Super Stock 89cc Cylinder Head Kit - Black Wrinkle

These S&S® Super Stock® high performance cylinder heads are designed for 1999-'05 engines with stock crankcase. They work well with engines of stock displacement , but are ideal for somewhat larger stroker or big bore engines up to 110". The 89cc combustion chamber provides a slightly higher than stock, but still manageable compression ratio in larger than stock engines. This makes them a good choice for touring bikes and other heavy vehicles. The large 2.000" intake and 1.605" exhaust valves maintain port velecity for good low and midrange response, but supply enough air for slightly larger engines to perform to their full potential. S&S® High performance valve springs allow the installation of camshafts with up to .650" lift. Intake ports flow 264 cfm compared to stock heads at 182cfm. S&S® High performance valve springs allow the installation of camshafts with up to .650" lift. Compatible with stock rocker boxes, exhaust, and intake manifolds. Black wrinkle powder coat finish matches stock black engine components.

The S&S Cycle 90-1106 Super Stock 89cc cylinder head kit is designed for 1999-2005 engines with stock crankcases. It works with stock-displacement engines and is also suited to somewhat larger stroker or big-bore engines up to 110 cubic inches. The 89cc combustion chamber provides a slightly higher-than-stock compression ratio while remaining manageable in larger-than-stock engines, making these cylinder heads suitable for touring motorcycles and other heavy vehicles.

Large 2.000-inch intake valves and 1.605-inch exhaust valves help maintain port velocity for low- and midrange response while supplying airflow for larger engines. The intake ports flow 264 cfm compared with 182 cfm for stock heads. S&S Cycle high-performance valve springs support camshafts with up to .650-inch lift. The heads are compatible with stock rocker boxes, exhaust systems, and intake manifolds, and feature a black wrinkle powder coat finish that matches stock black engine components.
