I recently put a HD high flow air cleaner on my 09 Flhx...it has been great and really allows for the bike to stretch its legs with the TFI and a set of rush pipes. The bad news is that I noticed a sound coming from that area today and pulled over asap to check it out ...one of my breather bolts was loose and banging around behind the chrome cover I pulled out the tool kit and tried to put it back in but it spun freely. When I pulled it back out it had the threads from the area it should be attached to wrapped around it. The air cleaner is secured by other bolts beside the breathers so it is not moving however the area around the rear breather bolt is sending a small mist out the side of the area where the air cleaner attaches to the throttle body. I was thinking of putting a small amount of liquid metal in threads and twisting in and let set...I just feel something needs to be done. Thanks for the input.
