INSTRUCTIONS:
1. First you must remove your stock air cleaner assembly and backing plate via the instructions in your
service manual. The carburetor flange and threaded bosses into the cylinder heads should then be cleaned.
Remove the backing on the supplied gasket and apply to the back of the large chrome backing plate.
2. Mount the large chrome backing plate to the cylinder heads via the supplied chrome spacers and breather
bolts. Spacers have a lip that helps them seat flush in the backing plate. Be sure to use Loctite when
securing the bolts. For Evo engines use the larger 1/2"-13 breather bolts. For twin cam engines, use the
3/8"-16 breather bolts. Tighten breather bolts lightly allowing minimal play in the backing plate for ease
with the next step.
3. Install the three supplied standoffs w/studs through the backing plate and into the carburetor flange.
Apply Loctite to the threaded studs on the standoffs and secure finger tight (tighten down as much as
possible by hand, they will be torqued in the next step). Secure the breather bolts to ~50in/lbs of torque at
this time.
4. Next install the seal plate that fits into the backing plate, sealing off the air/oil channels from the breather
bolts. Place filter over seal plate, and install black cinch plate with supplied black flat head bolts sealing the
air filter and seal plate to the backing plate. To help with orientation, there is a small divot machined into
the black cinch plate indicating the top center position. Be sure to apply Loctite to the three flat head bolts.
Tighten the bolts to ~50in/lbs of torque.
5. Lastly, place the chrome screen into the xXx cover and install over the air filter using the supplied polished
flat head bolt and Loctite. Tighten the bolt, clean off the cover and around the air cleaner assembly.
Installation is complete. Be sure to clean and re-oil your air filter on a regular basis. Also, be sure to
re-torque bolts after riding to ensure air cleaner assembly remains secure.
