may encounter clearance problems when re-installing the saddlebags. Check for a minimum of 5mm. clearance to prevent damage to the saddlebags. Measure clearance in the recessed area in the “backside” of the saddlebags where the shock sits. Check front, back and side clearance. THE BAGS MUST INSTALL WITHOUT UNDO FORCE. If they don’t, they are hitting the shock and/or shock boot. ****************** Inspect the clearance through the full range of motion of the swing arm ******************* n If more clearance is required, three suggested options are as follows: 1. Place washers between the mounting points where the saddlebags attach to the rails. This will move the bag slightly outward and away from the shock body. NOTE: On saddlebags utilizing DZUS FASTENERS (’85-’92), replace these with bolt/nut combination (as on ’93-’94 years). This will allow you to use washers to gain necessary clearance. 2. Remove or slide off the rubber boot that covers the shock shaft and attaches the body of the shock. The boot can be modified and reattached to the shaft (not the body) and secured with nylon ties and/or removed completely. This should gain you a minimum of 3mm of clearance. 3. Slot and/or space the saddlebag “rail/frame cage” mounting holes to allow the entire frame assembly to be moved out slightly from the shock body. You should use this modification only as a last resort n Lower motorcycle and check preload (shock spring stiffness). Adjustment may be necessary to suit personal preference in ride comfort. Read your Harley-Davidson owners manual for procedure. Test Ride.

Boring and Honing Procedures 1. Check again for burrs on cylinder gasket surfaces and remove burrs before performing Step 2. 2. Install original head and base gaskets, CYLINDER TORQUE PLATES (Part Number 33446-A) and TORQUE BOLTS (Part Number 33446-4). Tighten TORQUE BOLTS following tightening procedure given in the INSTALLATION, CYLINDER HEAD procedure in the ENGINE section of the Service Manual. NOTE Torque plates, properly tightened and installed with gaskets, simulate engine operating conditions. Measurements will vary as much as 0.001 inch without torque plate. 3. The cylinder must be bored with gaskets and torque plates attached. Bore the cylinder to 0.003 inch under the desired finish size. 1 WARNING CAUTION CAUTION 1 WARNING Kit Number 4. Hone the cylinder to its finished size (See Figure 1) using a 280 grit rigid hone followed by a 240 grit flexible ball hone. Honing must be done with torque plates attached. All honing must be done from the bottom (crankcase) end of the cylinder. Work for a 60 degree crosshatch pattern. 5. See Figure 1. After machining and honing, chamfer the bottom edge of the cylinder liner. the chamfer provides a beveled surface for easier installation of the cylinder over the piston rings. Break leading edge of liner to a flat surface. The bottom edge of the liner will be somewhat sharp after machining. This sharp edge could easily be damaged during installation of the cylinder. Piston Installation The 1200cc pistons have an arrow on the top of the piston. This arrow must face the front of the engine when piston is installed. There is no front cylinder piston or rear cylinder piston. New pistons can be installed in either cylinder. Check piston rings for proper side clearance and end gap (See XLH Service Manual). Be sure end gaps of adjacent rings are installed 90 degrees apart. Assembly Follow assembly and torque specifications given in the ENGINE section of the applicable Service Manual. Replace original gaskets, O-rings and seals with new components furnished in kit. NOTE Push rod covers on 1991 and later models are one-piece and the correct O-rings are as follows: Bottom – Part Number 17944-89 Upper – Part Number 11190 Engine Break In For the first 500 miles, to wear-in critical parts, observe these few simple driving rules: During the first 50 miles, keep the engine speed below 2500 RPM in any gear. Up to 500 miles, vary the engine speed, avoiding any steady speed for long distances. Engine speed up to 3000 RPM is permissible in any gear. Avoid fast starts at wide open throttle. Drive slowly until engine warms up. Avoid running the engine at extremely low RPM in higher gears. 2 of 3 -J00001 1200cc CYLINDER FINAL BORE SIZE AFTER HONING STANDARD BORE DIAMETER 3.4980 inch + 0.0002 inch Figure 1.
