SAFE INSTALLATION AND OPERATION RULES

Before installing your new S&S part it is your responsibility to read and follow the installation and maintenance procedures in these instructions and follow the basic rules below for your personal safety.

• Gasoline is extremely flammable and explosive under certain conditions and toxic when breathed. Do not smoke. Perform installation in a well ventilated area away from open flames or sparks.
• If motorcycle has been running, wait until engine and exhaust pipes have cooled down to avoid getting burned before performing any installation steps.
• Before performing any installation steps disconnect battery to eliminate potential sparks and inadvertent engagement of starter while working on electrical components.
• Read instructions thoroughly and carefully so all procedures are completely understood before performing any installation steps. Contact S&S with any questions you may have if any steps are unclear or any abnormalities occur during installation or operation of motorcycle with a S&S part on it.
• Consult an appropriate service manual for your motorcycle for correct disassembly and reassembly procedures for any parts that need to be removed to facilitate installation.
• Use good judgment when performing installation and operating motorcycle. Good judgment begins with a clear head. Don’t let alcohol, drugs or fatigue impair your judgment. Start installation when you are fresh.
• Be sure all federal, state and local laws are obeyed with the installation.
• For optimum performance and safety and to minimize potential damage to carb or other components, use all mounting hardware that is provided and follow all installation instructions.
• Motorcycle exhaust fumes are toxic and poisonous and must not be breathed. Run motorcycle in a well ventilated area where fumes can dissipate.

INSTALLATION

1. Remove the stock throttle body and intake manifold following the factory service manual for the particular bike you are working on.

2. With the stock throttle body and intake manifold removed, remove the fuel rail, stock fuel injectors, MAP sensor, manifold flanges and seals if they have not been already. Set these aside as you will re-use them.

3. Clean the manifold mounting surface of the cylinder heads to assure a positive manifold seal.
   NOTE: You won’t put fuel rail and injectors in the manifold until the manifold is installed loosely in the motor.

4. Place manifold flanges on the manifold, flat side toward the manifold and bevel toward head.

5. Install new manifold o-ring seals with the beveled side toward the flange and the flat side outward so that it contacts the cylinder head. Picture 1 illustrates the o-ring seal installed.

6. Install manifold on bike loosely.

7. Install the fuel rail and injectors into the manifold. Apply blue thread locker to the threads of the fuel rail bolts, install and torque to 100 in-lbs.

8. Lubricate the o-ring on the MAP sensor and install it in the S&S manifold. Apply blue thread locker to the screw that was removed that holds the MAP sensor in and tighten the screw to 20 in-lb. See Picture 2.

9. Pass the four bolts through the manifold flanges and thread into the head. Snug bolts up but leave loose, you will tighten later once the throttle body and back plate are installed.

10. Install the supplied o-ring into the manifold as illustrated in Picture 3.

11. Install the throttle body onto the manifold.

12. Install the air cleaner assembly per the manufacturer’s installation instructions

13. Once the air cleaner is installed go back and finish tightening the four manifold bolts that were left loose upon installation.
