Default Loud Metal Clanging

I have a 2007 Sportster 1200L and it was perfectly fine until a dead battery slowed down my riding, and while charging, I replaced the spark plugs with some NGK Iridium plugs, and now when I fire it up it runs but there is a god-awful metal on metal clanging going on and I'm having a hard time figuring out where it's coming from. Any insight helps. Cheers!

since you only changed the plugs can you verify the new plugs vs the plugs you removed as far as length in the hole.

Before I put in the new ones, I double checked that they were of similar length and they are.. I still have the old plugs, should I put them back in to see if anything changes?

Most definitely, when in doubt always undo the last thing you did before the problem showed up

Did you not tighten something up upon reassembly.? Also is it clanging sitting still or when riding? Things to tighten up? The seat , the sissy bar? isnt there a bracket holing the battery in? there is a cover for the battery, anmd anything else that you may have ratcheted bolts out of etc.

Hard to help without being able to hear the noise but don' think it's the plugs.

if it is plug length the OP can leave them in and run it , that will definitely make the noise go away....
