Rear Cylinder 1Rotate the engine so that the rear piston is at Top Dead Center (TDC), compression stroke, so no load is on the valves. 2Using a 3/16″ allen wrench, remove the four screws securing the rear cylinder rocker cover. 3Remove the cover and inspect both O-ring seals. Discard if damaged or worn. 4Push both rocker arms towards the valve end support bracket (A) and using a feeler gauge check the gap between the rocker arms and the pushrod end support bracket (B). NOTE: The Rocker arm end play specification should be between 0.003″ to 0.012″. 5 Compare the measurement to the specification an determine whether adjustment is necessary. If the end play is within specification, adjustment will not be required. Refit the rocker cover (instructions 14 to 15) and carry out the same inspection on the front cylinder . If the measurement is outside the specification, adjustment will be required and shimming will be necessary (follow the remainder of these instructions). Adjustment 6Using a 1/4″ allen wrench remove the 4 screws securing the rocker shaft assembly.Refit the LH support bracket and reposition the complete assembly on the rocker base. Make sure that the three dowels are in place and the slots in the rocker shafts are properly aligned with the mounting screw holes in the RH support bracket. 11Clean the threads of the 4 support bracket screws and apply Blue Loctite to the first 4 threads. 12Fit the 1-3/4″ screws into the LH support bracket (A) and the 2″ screws to the RH bracket (B). Torque all screws in cross pattern to 16-20 foot-pounds. CAUTION: The rear piston must be at TDC, compression stroke, when tightening the support bracket screws. 13Re-check the rocker end play to ensure it is within specifica- tion. 13Lubricate the two O-rings with clean engine oil and refit them in the grooves in the rocker base. 14Refit the rocker cover.

Step 1: Switch main dashboard switch to “off” position (Ignition& light switch) Step 2: Disconnect negative (ground) cable from the Battery Step 3: Remove the Condenser and Breaker points from the circuit breaker timing base. Step 4: Disconnect advance/ retard cable from timing base Step 5: Remove timing base from timer shaft and housing (see your manual for instructions) Step 6: Remove circuit breaker wire stud or circuit breaker to coil wire assembly from timing base Step 7: Remove circuit breaker wire from Ignition coil, and mark terminal on coil with piece of tape. Step 8: Install the Electronic Ignition Module on the timing base. Mount this short black wire to one on the timer base screws by keeping some slack in this wire so the timing base can turn free. Solder the flag terminal to this short black wire and mount it under the timer to motor bolt. This way of mounting provides a much better grounding. Do NOT use the screws (number 1 or 2 screws from picture below) from the timing base!!!! Step 9: Now three wires pass this hole via the rubber grommet. Figure 1 Figure 2 Step 10: Reinstall the timer base on the timer shaft housing, and keep some slack in the wires before protruding the hole in the timer shaft housing, and secure with ground spring and cover retainer. Reconnect the advance/retard cable to the timer base. Step 11: Route the two long wires to the ignition coil. Check in the HD service manual for a proper route to the ignition coil. (Keep away from hot surfaces like exhaust systems). Cut the wires to the exact length necessary for mounting. Step 12: Determine the exact length of the wire loom. Keep in mind that one end of the loom enters the timer shaft housing by 1cm. Cut the loom to the proper length. Step 13: Insert both wires in the loom. Strip both wire ends and solder the two flag terminals on the wires. Step 14: Connect the red wire to the ignition coil, on the terminal where the 6 or 12 volt is supplied to. This terminal has at minimum one wire connected which runs to the main switch. Step 15: Connect the black wire to the ignition coil on the terminal which is empty, and has piece of tape on it. (Old place where the circuit breaker wire was connected to) Step 16: Install the trigger rotor on the timer shaft cam, and tighten the hex screw by using the hex key tool. Do not over tighten the screw! Step 17: Check for clearance between trigger rotor and Electronic Ignition Module. Appropriate clearance is between 0,5mm and 1,5mm . Minor adjustments can be made by unlocking the two screws and slightly shift/move the Electronic Ignition Module. Check if the rotor moves free. Timing instructions: Remove the spark plugs from the engine, but keep them connected to the spark coil cables and engine ground. This enables normal operation of the spark, and prevents unwanted engine firing on compression stroke. See service manual or handbook for timing instructions of your model Step 18: Reconnect the negative (ground) cable to the battery. Step 19: Switch main power to “on” position. The red light in the Electronic Ignition Module might already light up. If not, turn the kick starter slowly. The red light is on while charging (closed points)the Ignition coil, facing solid metal of the trigger rotor. The light goes off (open points) when the end of the solid surface of the trigger rotor passes the centre of the Electronic Ignition Module. At that point a spark is generated by the coil

The majority of HSR42/45 installations use the Harley cable. Installation is simple when the installation instructions are followed, step by step. Those steps are: • Remove the stock Harley choke cable assembly. • Remove the spring and plunger from the stock cable. • Remove the Mikuni “Starter Nut” from the HSR. • Remove the Mikuni spring and plunger from the HSR. • Install the Mikuni spring and plunger on the Harley choke cable. • Install the Harley choke cable with the fitted Mikuni spring and plunger into the HSR carburetor. • DO NOT use the Mikuni Starter Nut; discard it. • DO NOT use the Harley spring or plunger; discard them. Note: If you do not have installation instructions, you may download them from the www.mikuni.com website in the “manuals” section. If the Mikuni Starter Nut is fitted to the Harley cable, the choke plunger is held off its seat and the choke is open all the time. If the Harley spring and plunger are used, the plunger does not seal and the choke is open all the time. The result, in both cases, is very poor fuel mileage (30 mpg or less). Another possible cause of poor mileage, rough idle and fouled spark plugs is incorrect cable routing. The stock Harley choke cable is very stiff and may not be fully seated in the metal elbow at the carburetor end of its run. This condition is easily corrected. On occasion, one of these errors may have been made by someone else at another location. The unfortunate mechanic who inherits the task of correcting the rich condition, poor idle and poor fuel mileage may have no clue as to the mismatch of parts. For this reason, we include the photos and text to help you discover if your installation is correct.

Turn ignition switch off and disconnect battery ground cable. 2. Refer to Figure 3. Remove OE ignition module and wire harness (items 1-4). You will disconnect two wires at the coil (15), a wire going to the VOES (Vacuum Operated Electrical Switch) (18), a black ground wire at the ignition module, and the 3 pin plug (20) that connects to the sensor plate (11). Refer to shop manual for locations. 3. Remove ignition cover plates and gasket (items 5- 9). This will require drilling out two rivets. The rivets will later be replaced with two supplied self- threading screws. 4. In order to remove the sensor plate cable, the cable plug (20) must be removed first. Use needle nose pliers to pull the terminals out of the plug. Then pull the cable through the exit hole at the bottom of the timing cover. 5. Note location of sensor plate (11). There is a V notch in the sensor plate used for alignment. When you install the HI-4, you should align the V notch in the same location. This should set the timing close enough to start the engine. Remove and save the two standoffs and washers (10). Remove the sensor plate (11). HI-4 INSTALLATION Refer to Figure 4. The HI-4 requires use of the OE timing rotor P/N 32402-83 (used only on 1985 and newer models). If you have an older model or are not sure, check the rotor (9) for the correct part number. For models prior to 1980, use the supplied 10-32 x ¾”bolt and washer to mount the rotor. 1. Install the HI-4 system in place of the OE breaker or sensor plate. Rotate the HI-4 about 90 degrees to give better access to the cable exit hole. Install the HI-4 first, then push the cable through the hole. On some early models it may be necessary to enlarge the wire harness exit hole in the gear cover. Align the V notch on the HI-4 same as the OE plate you removed. Use the OE standoffs to secure the HI-4. You must use lockwashers under the standoffs for proper clearance between the HI-4 and cover plate. Do not fully tighten the standoffs until the timing has been set. 2. Route the HI-4 wire harness along the frame rails up to the coil. Make sure that harness will not be chafed or burned by exhaust heat. Secure harness with tie wraps. Do not install timing cover. HI-4 HOOKUP Crimp terminals and hardware are supplied for your convenience. Use the ring terminals for coil hookup. Use male-female quick disconnects for connections to the tach and vacuum switch (VOES). Tape up any unused wires. 1. Circuit Breaker Cover Screws (2) 2. Circuit Breaker Cover 3.

The switched +12 volt wire will be hot when the ignition key is turned on. 2. Refer to Figure 5. Connect the HI-4 red wire and switched +12 volt wire to Coil positive. 3. The HI-4 white wire is not used and should be taped. 4. Connect the HI-4 black wire to the Coil negative terminal. 5. Connect the HI-4 green wire to the vacuum switch (Figure 3, item 18), if used. 6. Connect the HI-4 brown wire to the tach wire, if equipped with tach. Tape up if unused. 7. The HI-4 is grounded via the timing housing; a separate ground connection is not required. 8. Reconnect battery ground cable. Verify proper ground connections to the frame and engine. VOES HOOKUP The OE vacuum switch (VOES) is normally an open circuit. Above 3-5 inch-Hg vacuum, the VOES closes and grounds the vacuum input on the OE ignition module. This increases the total advance generated by the OE ignition module.
