My thought exactly… chk the preload on the bars (distance between mount to mount).
Chk the Bar Bushings as FX4w… stated too.
Bolt tightness use a Torque Wrench ALWAYS, loosen and double check if necessary.
Noise when using metal parts usually means metal to metal contact somewhere.
Thinking here… (smoke) check the Spring Bushings also; if you preloaded the bars too much and the Spring Bushings were on the weak side they may have broken down, maybe not but check just in case.
