1: Clean carbon from old guide O.D. before removal. 2: Guide to head press fit .0015″ / .002″ (head smaller than guide). 3: Heat head to approximately 200° – 250° F. 4: Install the guide at room temperature (Head hot & Guide at room temperature). 5: Let head cool to room temperature before final sizing of the bore. 6: Determine desired clearance valve to guide. Recommended clearance Shovel Head with cast iron guides Intake .001″ – .0015″ Exhaust .0015″ – .002″ (Ampco-45 add .001″) 7: Select the correct plug gage by adding the valve stem diameter and clearance desired for the finish diameter. 8: Select a plug gage .0005″ under finish size for the other end of the handle. 9: Finish hone the bore to size, check the size as you hone with the -.0005″ under size pin gage, finish hone to size with the finish plug gage pin. 10: Cut or Grind the seats, lap the valves to seats and check valve seat concentricity before assembling valve springs. 11: Use a good assembly lube, S’NS works great. 12: Use valve stem seals. Factory OE seals will stay tight with guide top size +.005″ to -.015″ from published size. 13: After the head is assembled and still on the bench check for any leakage valve to seat

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.

Follow the Transmission & Crankshaft section of your Victory motorcycle service manual for disassembling your Victory engine. 2-Your new S&S crankshaft and connecting rods will require assembly. S&S connecting rods aremachined to use the Orange Victory® rod bearings that are included in the kit (Bearing P/N 3514390-159). Perform rod bearing clearance inspection as follows: A-Wash or clean all of the following components: crankshaft crankpin, rods and rod bores, bearing inserts. B-Place a strip of Plastigauge®across the width of the crankpin. NOTE: Green Plastigauge (.001-.003″) is commonly used for this procedure, it can be purchased at the local automotive parts store. Do not place Plastigauge across oil holes. Be careful not to allow the rods to move during the rest of the inspection procedure. C-Mark the rod and cap at the separation line with a Sharpie®, Dykem®, or permanent marker to prevent rod caps from getting swapped from their original rod during the inspection and assembly process. See Picture2. Picture 1 S&S Crankshaft & Connecting Rods NOTE: Bearings not shown. 3 Picture 2 WARNING
D-Install connecting rods and bearing caps in the same order they were received. E-Torque rod bolts to 5 ft-lbs to seat caps. Then final torque bolts to 40 ft-lbs. F-Remove bearing caps carefully to prevent disturbing the Plastigauge®. G-Measure the widest part of the crushed Plastigauge to determine the rod bearing clearance. Do so by using the bands provided on the Plastigauge label. See Picture 3. H-Specification for oil clearance is: .00091″-.00279″ l If the resultant clearance is less than this specification, the bearings will need to be replaced with the thinner black color coded bearings, not available through S&S (Victory®P/N 3514390-067). l If the resultant clearance is greater than the specification, the bearings will need to be replaced with the thicker blue color coded bearings, not available through S&S (VictoryP/N 3514390-027). l If clearance is not within specification, clean old Plastigauge off components and reassemble rods to crankpin with a new strip of Plastigauge and the thinner or thicker bearings as determined above
