After installing my Holeshot headers, I now have a metallic vibration sound (like a metal part rattling against another metal part) at higher RPMs when the engine gets more buzzy. I've done my best to use my ears to locate the source, but I can only determine that it is in front of me while sitting on the bike. I think that rules out the possibility of the connection between the header and mufflers rattling, and also the possibility of a foreign object in my pipes rattling around.
The most obvious possibility is that one of the brackets used to mount the headers to the engine is vibrating against the header pipe, but it seems that would require the bolts to be loose to allow the rattling. Before i go loosen everything, jiggle things aimlessly to ensure they are resting in the correct position, then re-tighten, are there any experienced mechanics out there that know of any common "gotchas" with header installation?
For example:
It's kinda frustrating to have the willingness and desire to perform work on my bike myself; I know just enough to be dangerous and get myself into situations like this where I become completely helpless :angry:

For example:
- One of the header pipes does not seem quite centered in the opening to the engine; do I need to make sure the pipe is inserted into the opening such that it does not contact the wall of the opening?
- I had a qualified mechanic verify that there are no leaks at the mounting point (based on looking/listening while idling and revving); Is it possible to have a small leak that only occurs at high RPMs? Would it cause a sound that could resemble metallic rattling?
- Is it possible that the mounting nuts are tight enough to avoid leaks, yet loose enought to allow the brackets/pipes to vibrate?
