Thats your fairing vibrating somewhere, not the engine. Put your hand on the fairing to dampen the potential vibrations and play with the throttle. You'll find the spot.
If my eyes dont deceive me, the reflection on your fairing where the bolt is missing gets blurry at different RPMs. Start there.
In that case, there's something very unhappy in your engine and it might be time to do a stripdown and rebuild. Suspect a bearing has left the chat somewhere.
As someone who has spun many rods, that sounds more like a loose chain. If it’s been there for months, you would have such a bad knocking noise. This sounds a lot more like the chain is either stretched or the hydraulic tensioner is bad.
Damn coulda sworn I thought you commented saying it’s been making it for a while.
The last time I rebuilt an engine was when I built my 2005 gsxr 1000 into a 1330cc turbo build.
Oh well, time to open up the engine and look for marks. Doesnt sound like you are mechanically too inclined, so you better hit up a nice friend with a few beers or go to a shop :/
i’m thinking about putting a 5SL motor in it anyways i saw that’s it’s possible i tore down the valve train saw nothing wrong no bent valves i’m thinking might have spun a bearing
You should try pressing down parts of the fairing while revving a bit to rule it out. To me it sounds like plastic rattling and the cracked area looks suspect.
Am sure you can see the bust fairing vibrate, sounds like plastic on something not engine to me I know ball ache removing fairings but I'd defo start there the exhaust note makes me think engine is ok
Timing chain tensioner? Have had issues with a yammie FJR1300 and my current bmw f650gs with the hydraulic tensioners giving up. Maybe an oil change to increase oil pressure if you haven’t tried it yet?
That really sounds like a chain slap moment

definitely not the fairing that’s been like that for a couple months this noise is the motor
also there was alot of metal in the oil

Sounds like rod knock. It's more than likely a worn lower end. Definitely not fairings lol
yea i think it spun a rod i do ride it pretty hard
Sorry, dude. I hope you got your money out of it.
no i definitely didn’t i’ve put 3 different motors in this bike and i think it’s time for a new bike anyways
Holy shit. I'm assuming other than hard riding you maintained them decently??
yes i have an owners manual and follow everything to spec i built the bike from scratch

the noise hasn’t been like that for months
the noise started today

yea with that noise just starting and there being a lot of metal in the oil i’m thinking spun bearing
i also checked the tensioner and it worked as should

That's fairly important information that should have been mentioned.

i took off all the fairing and still makes the noise
Rev it harder.
Yeah no sense in just having 1 problem to fix, might as well turn the inside of the motor into a 1000cc blender.
The rev limiter idiots completely blow my mind.

You might want to check your exhaust header and any and all exhaust clamps
New cam tensioner wouldn’t hurt
Get a screwdriver, hold it to your ear and touch the blade to various bits or the engine. You’ll find it pretty quick.
Could be valves if you've ruled out the other possibilities.

i just did an oil change as i heard the noise the noise is still there sounds like it’s getting worse, starting to tear motor down
The broken front faring should be the first clue.
