Installing the S&S Cycle 55mm Performance Manifold Kit can significantly enhance your motorcycle's performance. Here's a step-by-step guide to help you with the installation process, ensuring optimal results:

1. Remove Existing Components: Begin by removing the stock throttle body and intake manifold. Refer to your motorcycle's factory service manual for precise instructions. Also, remove the fuel rail, fuel injectors, MAP sensor, manifold flanges, and associated seals. Keep these components aside, as they will be re-used.

2. Prepare the Manifold: Clean the manifold mounting surfaces on the cylinder heads meticulously. This is crucial for a secure seal. Position the manifold flanges on the manifold, ensuring the flat side faces the manifold and the beveled side faces the cylinder head. Install the new manifold o-ring seals with the beveled side toward the flange and the flat side facing outwards.

3. Install the Manifold Assembly: Mount the manifold onto your motorcycle, but do not tighten the bolts completely at this stage. Install the fuel rail and fuel injectors into the manifold. Apply blue thread locker to the fuel rail bolts, and tighten them to 100 in-lbs. Secure the MAP sensor into the manifold using blue thread locker on the threads, and tighten to 20 in-lbs.

4. Final Installation Steps: Thread the bolts through the manifold flanges and into the cylinder heads. Tighten them snugly, but leave them slightly loose initially. Insert the supplied o-ring into the manifold. Attach the throttle body to the manifold. Install your air cleaner assembly according to the manufacturer's specific instructions. Finally, tighten the manifold bolts completely. Apply the CARB EO number label to the frame down tube, either above or below the factory label.

5. Important Considerations: Always adhere to the installation instructions and utilize the hardware provided with the S&S Cycle kit. It is always recommended that you consult your motorcycle's service manual for the most accurate and up-to-date procedures. Always comply with all applicable federal, state, and local laws and regulations during the installation. Following these steps will help ensure a successful installation of the S&S Cycle 55mm Performance Manifold Kit, maximizing your motorcycle's performance.
