PICKUP PLATE INSTALLATION Remove the existing trigger/points plate and rotor, points cam and advance. Refer to the bike’s Service Manual for the proper procedure. EVOLUTION AND LATE MODEL SHOVELHEAD V-TWINS 1. From inside the cam/ignition housing, feed the free end of the MSD pickup harness through the wire access port. Note: The harness includes a heat-resistant acrylic sleeve that fits snugly inside the port opening. Do not pull the sleeve completely through the port. It must be positioned to protect the wires as they pass through the port opening. 2. Mount the MSD pickup plate inside the housing (Figure 1). Note the “adjusting notch” on the edge of the plate. This notch must be located over the series of “steps” inside the housing (about the 7 o’clock position as you face the housing). One of the sensor units will be at approximately 12 o’clock. SPORTSTER MODELS 1. On Sportsters, the wire access port must be enlarged. Use a 9/32″ drill bit to enlarge the wire port. 2. Remove the wire harness clamp of the pickup assembly and route the wires through the port. 3. Mount the MSD pickup plate inside the housing (Figure 2). Note the “adjusting notch on the edge of the plate. This notch must be located over the “cast notch” inside the housing (about the 11 o’clock position as you face the housing). The shorter of the two sensors will be approximately in the 9 o’clock position. 4. Install the hold-down/standoff screws with flat washers until they are snug – do not tighten at this time (Figure 3). 3. Put the MSD rotor in place on the end of the camshaft. The locating pin in the rotor bore must align with the groove in the cam. Do not force the rotor on the camshaft! Push the rotor into place until it is tightly against the end of the cam then snug the retaining screw. 4. Check the distance from the outer surface of the pickup plate to the end of the installed rotor (Figure 4). If necessary, add shims until the measured rotor height is 9/16″ (+/- 1/32″). 5. When the rotor height has been verified, remove the retaining screw, place a drop of Red Loctite on the threads and reinstall the screw to the factory recommended torque

throttle linkage with no cable modification. S&S Super E and G carb kits for 1936 to 1989 Big Twins contain a throttle cable guide (11-2339) designed for butterfly type throttle cables, and kits for 1990 and later Big Twins contain a taller throttle cable guide (11-2338) designed for CV type throttle cables. See Picture 2. The two throttle cable guides are interchangeable on the carburetor body, and can be changed very easily to update older carburetors or to accommodate custom throttle cables which are not stock for a particular year chassis. 1981 to Present Sportster Models Stock Sportster models from 1981 to 1987 have two cable throttle system designed for butterfly type carburetors. Sportsters from 1988 to present have a two cable throttle system designed for use with the stock constant velocity (CV) type carburetor. Since the taller #11-2338 cable guide bracket can not be used on a Sportster chassis due to insufficient frame clearance, throttle cables on Sportsters originally equipped with a CV type carburetor must be changed to butterfly style cables. S&S can supply the correct style throttle cables. See S&S Throttle Cable Application Chart.

S&S Throttle Kits S&S throttle kits fit 1″ handlebars and can be used on most chassis. (An adapter sleeve is available for use with earlier, 7 ⁄ 8 ” OEM handlebars originally equipped with internal throttle cable.) Barrel fittings on S&S cables readily “plug in” to S&S Super E, G, and stock H-D 1981-’90 butterfly type carb throttle linkage. Kits include one opening and one closing side cable, left and right grips, and handlebar clamps. Kits with 36″, 39″, 42″, or 48″ length cables are available. Length specified refers to overall cable length. Vinyl covered outer housing is 4″ shorter than overall length
