My Firebolt makes an unsettling metallic rattling sound when I get on the throttle. This only happens when I've been riding for a while (20-30 minutes in hot weather) and the engine is hot. What could be causing this?

At least this ones only 8 years ago. Oh Man, is this the same bike with a "Loud, hammering, noise"?! the you posted on the other necro-thread?
Direct link is pretty OG and I have no idea what a "hi power fuel pump" could be. The stock unit is fine for volume and anything other than 49 psi would be unusual and pointless.
Do you run premium fuel? is it old? Show us the timing table on the Direct Link you have to tune it.
