I was about to install the Screamin Eagle Stage 1 50mm kit (29260-08) to my Road King when I noticed a serious issue with the kit. It is not huge but can lead to great damage.
There are two holes drilled from the front of the mounting plate to the shafts of the mounting nuts. I assume airflow takes place here.
At the end of the holes inside the shafts are small splinters from drilling.
They come off as soon as you touch them, so some work on this is needed before installing in order to prevent these splinters get sucked into your cylinders (this is all BEHIND your air cleaner)
see picture hopefully that clarifies what I am trying to tell in my bad english:
