ENGINE MANAGEMENT AND FUEL SYSTEMS Cylinder heads on T-Series long block engines are 1999–’05 style Owners of 2006 models will need to purchase a set of 1999–’05 style, offset intake flanges such as S&S # 106-3516 Cylinder heads on these engines are specially machined to compensate for the non-stock cylinder length As a result, they are compatible with manifolds and throttle bodies with stock length intake runners In addition, the breather vent bolt locations have been adjusted so they are in the stock location, so stock style air cleaner Backplates will bolt up to these engines 2002–’06 EFI engines equipped with Delphi® fuel injection will require a performance tuner such as the Harley-Davidson® Race Tuner Carbureted engines will require a performance ignition module that allows adjustments to the advance curves The stock ignition module is not adjustable, and use of the stock module will likely result in engine damage due to knock from incorrect ignition timing Performance carburetors are recommended to achieve maximum performance S&S Super E carbs are ideal for T111 engines in touring applications, but a Super G will produce more top end horsepower S&S Super G carbs are recommended for T111 engines in performance applications, and for T124 engines in all applications The Oil Line Installation Kits are not required for the updated S&S T-series engines If the part number of the engine ends in "A," it DOES NOT need an installation kit FOR CLOSED COURSE COMPETITION USE ONLY. NOT INTENDED FOR STREET USE. LEGAL IN CALIFORNIA ONLY FOR RACING VEHICLES WHICH MAY NEVER BE USED, OR REGISTERED OR LICENSED FOR USE, UPON A HIGHWAY. NOT LEGAL FOR SALE OR USE NATIONWIDE ON ANY FEDERAL POLLUTION CONTROLLED MOTOR VEHICLE UNDER THE CLEAN AIR ACT.
