Back Plate Installation
NOTE
When servicing the velocity stack, apply Loctite 243 (blue) to all threaded fasteners (both male and female threads).
| 1. | 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. | |
| 2. | Apply a small amount of Loctite to the backplate mounting screw (13) threads. Use the four screws (13) to fasten the throttle body (B) to the velocity stack backplate (10). Tighten the screws to 55-60 in-lbs (6.2-6.8 Nm). | |
| 3. | Install the new O-rings (11) in the grooves around the breather screw holes on induction module side of the backplate (10). | |
| 4. | Insert the breather screws (9) through the backplate. Apply a small amount of Loctite (14) to the breather screw threads and the mating tapped holes in the cylinder head, then install the screws into the cylinder head. | |
| 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. |
Velocity Stack and Air Tube Installation
| 7. | With the countersunk holes facing outward, slide the mounting ring (5) all the way onto the intake tube (3), up to the flange. | |
| 8. | Place the gasket (8) against the opposite side of the flange. | |
| 9. | Align the holes in the gasket with the mounting ring (5) holes and notches in the intake tube flange. | |
| 10. | Apply a small amount of Loctite to the threads of the three flat head screws (4). | |
| 11. | 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). | |
| 12. | 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. Apply a small amount of Loctite to the threads of the set screw and 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) | ||
| 13. | Refer to the service manual and follow the instructions given to connect the battery cables, positive (+) cable first, and install the seat. |
WARNINGAfter 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)
