Installation of an S&S Super Stock cylinder head kit is easy and can be performed by any Harley-Davidson®repair shop equipped to do engine overhauls. No special tools other than those used in normal overhaul repair work are required. Read instructions thoroughly before starting work. When they are completely understood proceed with installation. 1. Remove Components and Inspect Parts Follow procedures outlined in appropriate Harley-Davidson® service manual to prepare motorcycle for top end service. NOTE: Disconnect batteryand drain all gasoline from gas tanks beforedoing any work. Gasoline is extremely flammable and explosive under certain conditions and toxic when breathed. Do not smoke. Perform installation in a well ventilated area away from open flames or sparks. A. Remove gas tanks and all other parts required to perform top end service. B. Remove carburetor, rocker covers, pushrods and pushrod tube assemblies, cylinder heads and cylinders. Also remove piston rings from piston. Do not remove pistons. NOTE: Be careful not to introduce any dirt or other foreign material into crankcase during disassembly of engine. Metal filings, dirtand any other foreign contamination in engine may cause premature wear and/or irreversible damage to bearings and other internal engine components. C. Thoroughly clean and inspect all parts that are to be reused. Any parts that show signs of wear or damage should be replaced. WARNING CAUTION 2. Check Piston Alignment in Cylinder Bore The purpose of this procedure is to check for and correct possible piston misalignment in the cylinder bore. During normal manufacturing, engine components such as crankcases, cylinders, and connecting rods can be machined to dimensions within factory specifications but on the extreme ends of the tolerance range. Sometimes these components when combined together form an assembly that is borderline or actually “out of print”. The worst result isthat the pistons can run cocked in the cylinder bores causing the connecting rods to thrust to the sides exerting unnecessary stress on the pistons, rings, rod bearings and other related parts. This procedure is not the same as blue printing, but it provides almost the same result. We feel that not enough emphasis is given to checking the piston alignment in the cylinder bore.

Measuring Piston-to-Valve Clearance After installing non-stock cams, check piston-to-valve clear- ance. 1. Apply 1/8-inch (3 mm) layer of clay to crowns of pistons in areas where valves meet pistons. 2. Refer to the appropriate Service Manual and assemble the heads and valve train, and tighten cylinder studs to torque specified. 3. Turn engine through two complete revolutions by hand. 4. Remove heads and measure clay at its thinnest point. NOTE Clay must measure 0.080 inch (2.03 mm) at its thinnest point. If this measurement does not meet minimum thickness, depth of valve notches must be increased. The depth of the notches must not exceed 0.135 inch (3.43 mm). Measuring Valve-to-Valve Clearance NOTE Wait ten minutes before turning the engine after installing push rods. This allows tappets to bleed down and prevents you from bending push rods or valves. 1. Rotate the engine so that both valves of the front cylinder are partially open. Shine a light through the exhaust port and look through the spark plug hole to view the valves. Turn engine, if required, to the point where the exhaust evel sensor to the fuel pump with screw (3). Tighten the screw enough to seat the fuel sensor against the mounting tab e. Route fuel level sensor wiring under the fuel hose and connect the fuel level sensor to the low fuel switch connector on the fuel pump module. If necessary use the jumper harness (Figure 4, item 5). f. See Figure 2. Secure the fuel pump wires and con- nectors

Intake system Fresh air is drawn into the filter box through the intake snorkel 1 , past the carburetors 2 and through the air filter 3 . The cleaned air is conducted to the combustion chamber through the carburetors and intake ports. 1 2 2 3 2-4 Repair manual KTM LC8 Art.-Nr . 3.206.016-E Secondary air system The secondary air system supplies fresh air to the emissions in the exhaust port, resulting in the afterburning (oxidation) of the emissions. A line leads from the filter box 1 to the control valve 2 which opens as soon as the throttle valves 3 are opened. The line continues to the reed valves 4 in the cylinder heads which are actuated by the pressure pulsation in the exhaust system. As a result, cleansed fresh air arrives in the exhaust port. The oxygen content in the air and the high exhaust gas temperature cause the emissions to oxidize. If the throttle valves are closed and the engine goes into an overrun condition, the underpressure in the intake port will rise and the control valve will close. This prevents exhaust backfire (combustion of the unburned fuel/air mixture). 1 2 3 3 4 4 4 2-5 Closed thermostat The thermostat is closed if the temperature of the cooling liquid drops below 75°C. The water pump 1 pumps the cooling liquid through the cylinder and cylinder heads 2 and the thermostat 2 . Open thermostat The thermostat 3 opens at 75°C. The water pump 1 pumps the cooling liquid through the cylinder and cylinder heads 2 , the aluminum cooler 4 and the thermostat. The pressure in the cooling system (max. 1.4 bar) is regulated by a valve in the radiator cap 5 . The cooling liquid level in the compensating tank 6 must be between the MIN and MAX marks when the engine is cold. The fan 7 switches on at 102°C.
