For maximum piston and ring life, fit pistons using close fit dimensions. Close fit requires absolute adherence to new engine break-in as described on page 7. 2. For immediate drag strip use, fit pistons using loose fit dimensions. Break in rings and pistons with 50 easy miles if possible. Piston and ring life will be reduced with loose fit dimensions. 3. Measure all pistons at widest point across thrust face, perpendicular to wristpin hole. Several measurements should be taken to locate widest point. Typically, this will be at bottom of piston skirt for pre-1984 big twins, and approximately 1⁄ 2 ” below level of wristpin hole in pistons for Harley- Davidson®Evolution®and Twin Cam 88®engines. If pre-1984 piston is notched for placement in rear cylinder, use measurement directly above notch for skirt measurement. 4. S&S®recommends #220-#280 grit stone for final honing of stock bore and Sidewinder®, S&ST124 and S&S big bore cylinders. #320 grit stone is recommended for engines using S&S 92-4500, 92-4510, or 92-4520 pistons. 5. Follow procedure recommended in Harley- Davidson®service manual for boring and honing stock bore big twin and Twin Cam 88®cylinders. Follow instructions included with S&S Cylinder Torque Plate Kit when boring and honing S&S 35⁄ 8 ” or 4″, 41⁄ 8 “bore cylinders. Torque plates must be used to simulate compressive stress in an assembled engine. Cylinders will distort if torque plates are not used.

Definitions: Grounding : The process of making an electrical connection to the general mass of the earth. This is most often accomplished with ground rods, ground mats or some other grounding system. Low resistance grounding is critical to the operation of lightning protection techniques. Bonding : The process of making an electrical connection between the grounding electrode and any equipment, appliance, or metal conductor: pipes, plumbing, flues, etc. Equipment bonding serves to protect people and equipment in the event of an electrical fault. Equipotential Bonding : The process of making an electrical connection between the grounding electrode and any metal conductor: pipes, plumbing, flues, etc., which may be exposed to a lightning strike and can be a conductive path for lightning energy towards or away from the grounding electrode. 2. The National Fuel Gas Code NFPA 54/ANSI Z223 states, “Each above ground portion of a gas piping system upstream from the equipment shutoff valve shall be electrically continuous and bonded to any grounding electrode, as defined by NFPA 70, National Electrical Code ( ANSI/NFPA 70 1999 Edition.) 3. The TracPipe® gas piping system shall be bonded in accordance with the National Fuel Gas Code, NFPA 54/ANSI Z223. The piping system is not to be used as a grounding conductor or electrode for an electrical system. 4. For bonding of the TracPipe® system, a bonding clamp must be attached to the brass AutoFlare®fitting adapter (adjacent to the pipe thread area – see Figure 4-21) or to a black pipe component (pipe or fitting) located in the same electrically continuous gas piping system as the AutoFlare®fitting. The corrugated stain- less steel portion of the gas piping system SHALL NOT be used as the bonding attachment point under any circumstances. Bonding electrode conductor sizing shall be in accordance with Article 250 (Table 250-66) of ANSI/NFPA 70. The bonding is a requirement of the National Electrical Code

1. Appliances . Carefully review the appliance manufacturer’s installation instructions for positioning the unit, any special venting or connector requirements, and verify that it is a Category I appliance or an appliance that requires the use of Type B gas vent. 2. Placement . The placement of the vent and fittings must be in accordance with Local Codes, as well as accepted venting practices. If more than one appliance is to be connected to one venting system, the common vent must be correctly sized. It is a good idea to make a sketch of the proposed installation, labelling the components you will need. Adjustable Pipe Lengths are available to make up odd lengths. Minimize the number of turns and lateral runs, as the National Fuel Gas Code places limitations on these. A 45° turn is preferable to a 90° turn. The appliance reference material should be consulted at this time, as well as any Local Authority having jurisdiction. In most localities, building permits are required for any new appliances, or modifications to existing venting systems.
3 3. Figures 1 , 2, & 3 show examples of some typical residential installations . 4. Clearance to Combustibles . A 1-inch clearance (air space) to combustible materials must be maintained , when using Simpson Dura-Vent Round B- Vent, regardless of the pipe diameter. 5. Combustion Air . Refer to appliance installation instructions and local building codes to ensure compliance with required volume of combustion air for each appliance installed . 6. Slope . If the venting system contains lateral (horizontal) components, they shall be positioned so they have an upwards slope away from the appliance of not less than 1/4- inch rise per foot of run. (Horizontal vent installed in attics, unconditioned area, or between floors have further restrictions, please consult your local building codes for specific limitations.)

Slide connecting rods and bearings over crankpin. C. Rotate rods on crankpin, and observe clearance between rod and sprocket shaft nut. D. If additional clearance is needed, remove material from sprocket shaft nut. Do not remove material from connecting rod. E. Repeat procedure for camside flywheel and pinion shaft. 2. Female rod crankpin end to inner flywheel rim – .060″ clearance recommended. A. While checking female rod to mainshaft clearance, observe clearance between crankpin end of female rod and rim of both flywheels. B. If additional clearance is required, remove material from flywheel at point of contact. Do not remove material from connecting rod. 3. Wristpin end of both female and male rods to flywheel edge -.060″ minimum clearance recommended. A. While checking female rod to mainshaft clearance, observe clearance between wristpin end of both rods and rim of both flywheels. B. If additional clearance is required, remove material from flywheel at point of contact. Do not remove material from connecting rod. 4. Wristpin end to crankcase and cylinder – .060″ is recommended in these areas. A. With the camside flywheel and rods mocked up, install the assembly in the right crankcase half with pistons (less rings) and cylinders in place. B. Rotate flywheel through one full revolution and check for rod to crankcase and cylinder spigot contact on both the front and rear of each cylinder. C. File or grind crankcase or cylinder spigot as needed to achieve .060″ clearance. Do not remove morematerial than needed. D. Repeat for left crankcase half. NOTE: Whenever clearancing is performed in any of these areas, do not remove any material from the connecting rods as clearancing on the rods may unnecessarily weaken them. Make adjustments to the point of contact on the mainshaft nut, flywheel rim, crankcase, cylinder spigot, etc. Connecting rods weakened by clearancing may fail causing serious engine damage.

Remove Old Carburetor WARNINGS ● Gasoline is extremely flammable and explosive under certain conditions. Do not smoke around gasoline. Gasoline fumes are toxic when inhaled. Perform installation in a well ventilated area away from open flames or sparks. Any gasoline leak or spill constitutes a health and fire hazard. ● If motorcycle has been running, wait until engine and exhaust have cooled to avoid getting burned during installation. ● Electrical sparks can ignite explosive gasoline fumes. Failure to disconnect battery while working on motorcycle can also result in inadvertent engagement of starter and personal injury. A. Shut off fuel petcock and disconnect battery. B. Remove air cleaner assembly. Drain fuel from existing carburetor. Remove carburetor, manifold, choke cable and any carburetor mounting hardware NOTE – Removing and tightening hard to reach Allen bolts such as carb-manifold mounting bolts and V2 manifold flange bolts can be greatly simplified by the use of Allen ball-end drivers. These tools are available at most automotive and tool supply houses. See Picture 9. Additionally, Performance Plus of Evansville, Indiana, produces a hex wrench specially modified for accessibility of V 2 manifold bolts. Call 812-963-8854 for further information. As alternative, standard hex wrench can be shortened for convenience. NOTE – Some Buell motorcycles have a breather fitting with 90° elbow on rear head. Due to proximity of frame, elbow must be removed before fitting can be taken off engine. Loosen fitting and rotate to position convenient for cutting elbow. Secure fitting by tightening against cylinder head. Elbow may be inaccessible to hacksaw. In most instances, a die grinder with cutoff wheel will remove elbow with little difficulty. If die grinder is unavailable, grasp elbow firmly with pliers and snap off, then remove fitting. CAUTION – Extreme care must be taken to prevent metal chips from entering engine when elbow is removed. S&S recommends packing breather fitting with gease before removing elbow. Metal chips inside engine will cause extensive damage. Installer bears all responsibility for containment of chips and other debris. Picture 2 Picture 4 Picture 3
