INSTALLATION Installation of this kit is divided into six steps: 1. Big-Bore Cylinder and Piston Conversion 2. High Performance Camshafts 3. High Performance Clutch Diaphragm Spring 4. High Performance Air Cleaner 5. Calibrate the ECM 6. Exhaust NOTES This Big-Bore Stage 2 kit is intended for High Performance applications only. This engine-related performance part is legal for sale or use in California on pollution-controlled motor vehicles. Engine-related performance parts are intended for the experienced rider only. -J04173 1 of 5 The air cleaner contained in these kits is designed to perform with these kits only. Any other combination of components is not confirmed to be legal for street use. The Product Information Label contained in this kit is required in the state of California only. This label is required to aid in passing the California Smog Check Program. Place the Product Information Label on the right side of the frame, directly beneath the VIN sticker. Do not place the label on motorcycles other than those specified in the Instruction Sheet. Gaskets provided in the 1690 conversion kit eliminate the need for original head gasket O-rings. For this reason, DO NOT install the Original Equipment (OE) O-rings (Part Number 11273) to the top of cylinder dowels, or severe engine damage may occur. Big-Bore Cylinder and Piston Conversion NOTE Installation of this kit requires removal of the cylinder heads, cylinders and pistons. Refer to Section 3, ENGINE: STRIPPING MOTORCYCLE FOR SERVICE and TOP END OVERHAUL of the applicable Service Manual for instructions. High Performance Camshafts NOTE Installation of this kit requires removal and re-installation of the cam support plate. Refer to Section 3, ENGINE: BOTTOM END Cam Support Plate, Removal and Disassembly/Assembly (Camshaft, Camshaft Bearings) of the applicable Service Manual for instructions. 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
