Installed the A.N Big sucker a while back. Everything is always done meticulously. Torqued to spec etc.
Riding today, and noticed weird noise..
Get back to the house and localized it IVO the intake.
Take it apart.. filter off. Next.. the 3 big hollow bolts that the filter screws into.. except the top two are loose.
Great! found my problem!
went to tighten them by hand.. except they just spin. Pulled them out and the threads from the throttle body came out with them.
So who else has had this happen. Is this covered under warranty by Harley?
I beg to differ...give dealership a try. This could've been from factory build and your install was the camel-back breaking straw. You never know until you try...IMO.
What ever the outcome, choose your thread products wisely. Use red and blue LocTite appropriately as well as copious amounts of anti-seize on other critical locations. Steel into aluminium is always a good candidate for anti-seize.
It 'aint the end of the world and it's easy to get to, just re-thread it...(stick a rag in the intake before you start though!!)
It happened to me twice with the two bolts that hold my Screamin' Eagle heavy breather on. The stock breather bolts just don't have enough thread engagement if you ask me. Roughly 1/2". I made some new breather bolts that give an additional 3/8" engagement. The threaded hole in the heads are plenty deep enough. Been good so far.
