INSTALLATION
WARNING
To prevent accidental vehicle start-up, which could cause death or serious injury, disconnect battery cables (negative (-) cable first) before proceeding. (00307a)
WARNING
Disconnect negative (-) battery cable first. If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00049a)
  1. Refer to the service manual and follow the instructions given to remove the seat and disconnect the battery cables, negative (-) cable first. Retain all seat mounting hardware.
WARNING
When servicing the fuel system, do not smoke or allow open flame or sparks in the vicinity. Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. (00330a)
Original Equipment (OE) Air Cleaner Removal
For EFI (fuel-injected) models: Have a Harley-Davidson dealer recalibrate the ECM prior to air cleaner installation.
  1. Remove the air cleaner backplate following the instructions in the service manual. Retain the two breather screws (A) removed from the backplate (see Figure 1 ). The remaining parts can be discarded.
  2. See Figure 1. Remove and discard induction module bracket (B).
Back Plate Installation
NOTE
When servicing the velocity stack, apply Loctite 243 (blue) to all threaded fasteners (both male and female threads).
1. Install the new O-rings (11) in the grooves around the breather screw holes on induction module side of the backplate (10).
2. Remove the backing from the adhesive side of the backplate gasket (12). Carefully align the holes, and install the gasket on the induction module side of the backplate.
3. Insert the breather screws (removed in Step 2) through the backplate. Apply a small amount of Loctite (13) to the breather screw threads and the mating tapped holes in the cylinder head, then install the screws into the cylinder head. DO NOT tighten completely at this time.
4. Apply a small amount of Loctite to the backplate mounting screw (9) threads. Install the screws all the way through the backplate and gasket until the screw threads are captured in the induction module. DO NOT tighten completely at this time.
5. Alternately tighten the two breather screws to 13.6–16.3 N·m (120–144 in-lbs).
6. Lubricate the O-rings (7) with clean engine oil or white lithium grease. Install the O-rings onto the breather plugs. Press the breather plugs (6) into the breather screw cavities.
7. Tighten the three backplate mounting screws to 6.2–6.8 N·m (55–60 in-lbs).
Velocity Stack and Air Tube Installation
8. With the countersunk holes facing outward, slide the mounting ring (5) all the way onto the intake tube (3), up to the flange.
9. Place the gasket (8) against the opposite side of the flange.
10. Align the holes in the gasket with the mounting ring (5) holes and notches in the intake tube flange.
11. Apply a small amount of Loctite to the threads of the three flat head screws (4).
12. Secure the intake tube, mounting ring and gasket to the backplate, and tighten the screws to 6.2–6.8 N·m (55–60 in-lbs).
13. Install the velocity stack (2) onto the intake tube until velocity stack bottoms out on tube. Position velocity stack so that the set screw (1) is located towards the inside of the tube closest to the engine. Tighten the set screw to 3.4–4.5 N·m (30–40 in-lbs).
WARNING
Connect positive (+) battery cable first. If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00068a)
14. Refer to the service manual and follow the instructions given to connect the battery cables, positive (+) cable first, and install the seat.
WARNING
After installing seat, pull upward on seat to be sure it is locked in position. While riding, a loose seat can shift causing loss of control, which could result in death or serious injury. (00070b)
