STEP 1 Remove the seat, fuel tank, and OEM air cleaner assembly. Disconnect the hoses connected to the air cleaner while leaving them connected to the motorcycle. Save the clamp that secures the air duct to the carburetor and the OEM fasteners used to secure the stock air cleaner assembly to the motorcycle as some will be reused. STEP 2 Remove the carburetor according to the section in your Road Star factory service manual that outlines procedures for carburetor removal, disassembly, reassembly and installation. Now is a good time to proceed with re-jetting the carburetor. We have supplied jets to cover many common configurations. For jet locations and jetting recommendations with various exhaust combinations see Addendum I. Since the OEM screws retaining the float bowl are easily damaged, we have included replacement M4 socket head cap screws to replace them, if necessary. STEP 3 Insert the rubber intake duct into the main support bracket as shown in PIC. 1. The rubber nipple should be pointing toward the longest leg of the bracket. STEP 4 Insert the rubber intake duct into the Pro R-series Hypercharger in the same fashion it was installed in the main support bracket. See PIC.2. You may need to use a screwdriver to help “poke” the flange of the Rubber Intake Boot into position inside the Pro R-series Hypercharger. STEP 5 Line up the three holes in the back plate of the Pro R-series Hypercharger and the three holes in the flange of the rubber intake duct with the three holes in the main support bracket. Insert the three supplied 1/4″-20 x 5/8″ socket head cap screws from inside the Pro R-series Hypercharger and secure on the back side of the main support bracket with the 1/4″-20 thin nylock nuts. You will need to pull back the inner flange of the rubber intake duct to access the holes. Hold the nylock nuts with a 7/16″ wrench as you tighten the socket head cap screws with a 3/16″ hex key. Be careful not to over tighten and cause the rubber intake duct to pucker around the nylock nuts. See PIC.3.
