How to Install an S&S Super E Carburetor Kit on a Harley-Davidson

Preparing for Carburetor Installation

• 🛠️ Begin by removing the horn and choke cable on the left side of the bike to gain access to the manifold.
• 🔌 Unplug the MAP sensor from the stock manifold, as it will be transferred to the new one.
• 🔧 On the right side, loosen the throttle cables by rolling the lock nuts down to create slack, allowing for easier removal of the old carburetor.

Removing the Old Carburetor and Manifold

• 💨 Carefully detach the old carburetor from the manifold, using a pick if necessary to help disengage the cables.
• 🔩 Remove the old manifold by taking out the screws securing it to the cylinder heads, noting that access can be tight.
• 💡 Save the MAP sensor from the old manifold for installation on the new one.

Installing the New S&S Manifold

• ⚙️ Install the MAP sensor into the new manifold, applying a small amount of grease and tightening to 15-20 inch-lbs.
• ⬅️ Ensure the manifold flanges are oriented correctly, with the slot facing the left (rear) side of the bike and the 'F' and 'R' markings aligned with the front and rear heads respectively.
• 💧 Place the rubber seal with its taper facing down between the manifold and the flange for a proper seal against the cylinder head.
• 🔗 Tighten the manifold screws evenly to ensure the seal seats flat and prevent intake leaks, aiming for 15-17 ft-lbs if possible, or tightening sequentially.
• 🔌 Connect the vacuum line from the old carb to the new manifold and plug in the MAP sensor.

Setting Up the S&S Super E Carburetor

• 🎯 Set the idle air mixture screw by threading it in until it bottoms out, then backing it out one and a half turns.
• ⚙️ Adjust the idle speed screw by running it down until it contacts the wheel, then backing it out half a turn.
• 📎 Install the cable guide with a dab of blue Loctite and snug it down.
• ⛽ Attach the fuel line and overflow tube to their respective fittings on the carburetor.

Mounting the Carburetor and Air Cleaner

• 🛡️ Install the heat shield and throttle cables onto the carburetor before mounting it to the manifold.
• 🧱 Use the insulator block between the carburetor and manifold, ensuring the smooth side faces the O-ring on the carb and the O-ring faces the manifold.
• 🔩 Secure the carburetor to the manifold with the two large Allen screws, applying blue Loctite and tightening to approximately 15 ft-lbs.
• 🎛️ Assemble the enricher lever on the backing plate, carefully layering the washers and securing with the small screw, ensuring the lever operates smoothly but stays in place.
• 💨 Install the backing plate and gasket, tightening the three Allen screws to 60-84 inch-lbs, ensuring the lever notch aligns with the pin.
• 🌬️ Install breather bolts with shims if needed to account for any gap between the backing plate and cylinder head, torquing them to 8-12 ft-lbs without Loctite.
• 🎨 Attach the air filter and teardrop cover, then reinstall the motor mount with appropriate torque specifications for the bolts.

Final Steps and Tuning

• ✅ Readjust cables, reinstall the fuel tank, and add fuel to complete the installation.
• 🔧 S&S provides ample jets in the kit for tuning, and additional tuning videos are available.
• ⏱️ Allow approximately two hours for this installation, which requires basic hand tools.
