S&S Cycle offers a new one-stop set-up kit that includes the company’s three-piece 4-5/8” stroke flywheel assembly and 4-1/8" cylinders and Easy Start Gear Drive Cams.
Three variations are available. The first includes S&S 91cc Super Stock Cylinder Heads for 10.8:1 compression ratio. The second includes Flat-Top pistons to be used with owner's 89cc S&S cylinder heads for 11.1:1 compression ratio. The third includes dished pistons to be used with owner's OE cylinder heads for 10.8:1 compression ratio.
All kits, which are offered in a black or silver finish, install in stock crankcases, which keep costs down, according to Pete Amenda, marketing director.
Professional installation is required; allow for 15 to 20 hours, Amenda says. Fuel system and ignition are not included. – Dave Koshollek
