Good afternoon everyone. I have a 2015 SGS. I've been running a Vance and Hines VO2 Grenade and want to go back to the stock air cleaner assembly. I can't for the life of me remember how to re-install the original assembly "FROM THE HEADS". The "service manual" shows the air cleaner assembly from the PLASTIC "Backplate" to the air cleaner cover. PROBLEM IS....I can't find anything that shows the assembly FROM THE HEADS. They fail to show the 2 black, 1 inch tall metal inserts that the breather bolts go through when they connect to the heads, the METAL backplate and the 3 strange looking 13 mm screw/bolts that actually attach the metal backplate to the throttle body. Every "figure" or "You Tube" video instructs from the PLASTIC backplate to the cover. That PLASTIC backplate is not what is attached to the heads. NOT TO MENTION....I totally remember the Breather "TUBE" being attached to the METAL backplate, NOT the PLASTIC backplate. If that explanation doesn't make sense, I can send pictures. PLEASE HELP!!! As you can see, I'm a bit frustrated.
