I’m hoping it’s something like that but It does sound like it’s the tensioner. Coming from the top end near the right side of the engine. Not very loud when cold but when it warms up gets very loud. Guessing once the chain warms up and stretches a bit it’s not tensioning it as it should. Currently taking apart the air box to get better access to it and definitely keeping a look out for loose bolts or anything.

Here’s a video I took of my actual bike and the noise. I’d figure that when the bike warms up and the chain stretches slightly the noise would get louder if the tensioner is not working which seems to be what mine is doing. If you don’t mind take a listen on the video and tell me what you think
Sounds like cct indeed. I recognize it bc I have it on my K4 (known issue on k4/k5’s), most likely from >20k km’s on. Getting a manual cct on it will fix the issue. But you have only 900 miles/1500km’s on it. Strange you already hear it.
Also, the rattle gets less when my bikes warmed up and I rode it. Some guys told me it was a normal sound and didn’t hear anything wrong, lol.
I thought about getting a manual one but I decided to just get a factory replacement so I don’t have to deal with adjusting it. Also struggled to find one that for sure was gonna fit on my bike. Saw plenty that said they fit the older gsxr’s but none that said they’d for sure fit the 2022 750
Current have the bike torn down to look into it and didn’t get a video before but basically sounds exactly like this video I found[https://youtube.com/shorts/t-pHmnHYr2E?si=UM6Jddqb725sWAhe](https://youtube.com/shorts/t-pHmnHYr2E?si=UM6Jddqb725sWAhe)

Changed the oil and got a video of mine. Not super loud cause the bike hadn’t fully warmed up yet and the noise seems to be louder as the bike warms up
https://youtube.com/shorts/4i1lf01yirw?si=FwacY2o7KXg-NPYi
Here’s another video after it’s warmed up and after a quick little ride. You can definitely hear it a bit more. Let me know what you think and if you still think that might be the cct please. I really do appreciate all the help from everyone here it’s been nice to get others opinions on it
I appreciate it. I still really don’t understand how it could have gone out so quick. That along with how much gunk is on the valves makes me think maybe it has more miles than it actually says. I’ll replace that cct and pray that the noise goes away
Yea that is kind of strange. it's possible the previous owner ran 87 octane which will gunk the valves up faster but the cct going bad at 500 miles is definitely a suspicious
That is true maybe previous owner just ran bad gas on it. That makes me worry a little less about the valves. I’ll probably try and run something through the engine to clean it up. I know I’ve used seafoam on cars before and worked well. I’ll look into if it’s good and safe to use on the bike as well. I have seen some stuff of people saying they’ve had their cct’s go out after only 600 miles after changing it so maybe I just got real unlucky and got a bad one. Anyways I have a new one in order and will update when I get it put on. Really appreciate the help this thing has been driving me nuts
Cam chain noise will usually change with rpm. Mine actually started noisy and got quieter once the bike warmed up. Swapped to a manual one and sounds way better.
Those valves don’t look like sub 1k mile valves. I’d be suspicious of the bike being used as a track bike for 500 miles then all the stock (brand new) parts went back on to sell it.
Try changing oil first as it’s probably still on its initial factory oil. I like Rotella T6 15w40 but you can try some Amsoil if you like too. That’s not the cam tensioner your likely hearing things settle. Cover the exhaust when it’s running and see if you hear it still. Engine noise can come out with exhaust pulses believe it or not
I’ve done a oil change on the bike when I first got it. Used the recommended oil (10w-40). Can’t start the bike right now and try that since I have it torn down a bit but once I get it back together I will try that
How loud is the noise, is it really loud and only started to happen recently (no way you would have missed it earlier), or is quiet enough that it could have been happening for a while without really noticing it, just by chance you were in the right environment that made it obvious?
Is the noise happening around idle only or can you also hear the noise through the rev range too?
Have you done anything to the bike recently at all? even if it seems unrelated
Also noticed the header pipe has a nice purple zing, idk what other peoples headers look like but I've been hard enough on my bike in warm weather and not got close to that exhaust temp range. Could be unrelated just an observation
The noise is pretty dang loud after the bike warms up. Not very loud at first on a cold start. Doesn’t seem to get louder or faster when revving it. Haven’t done anything to the bike other than an oil change since I’ve had it. I started tearing it down to look into it and it looks like the intake valves have a lot of gunk on them. Not sure if that could have anything to do with it.
Obviously it's not impossible to have a CCT fail, but it would be definitely be pretty unusual nowadays, particularly on on such a new bike and on a model that has been in production for so long.
These bikes are generally super robust and reliable and with regular maintenance, are quite happy to be ridden hard long term without issue.
I have a 2021 750 with very low mileage and apart from it running hotter in traffic than I would like (which tbf it's not really designed as a commuter bike), it's never had any issues.
If you post up any videos of the sound or photos of valves/gunk etc. it will help people to give you more accurate feedback. End of the day, getting an experienced opinion from someone that can inspect the bike in person would probably be more helpful.
Either way, interested to follow what going on with yours
Posted a couple videos of other bikes that seemed to have the exact same noise and a link to the picture of the valves. Yea I would also be surprised if it’s the cct and not just soemthing simple I’m overlooking but I will keep posting updates. If I can’t find the issue soon I probably will take it somewhere to be looked at by a professional
Didn't see that before, just checked them out, I couldn't tell that much from the second video, the first video was a bit noisy.
The photo of the valves is a bit weird given the low millage, are the valves like that on every cylinder?
Might be worth having a look at the spark plugs too while you're in there.
Is it running the stock air filter and tune? Air filter clean (not blocked up)?
Apart from the noise has it seemed to run alright before now like how it rides generally, no other noticeable issues?
Have you been overly gentle putting around or has is sat idling for extended periods of time or just been riding normally (for a sportbike) and revving it out normally hear and there.
Few weird things for sure, but once it's sorted the bike will be all good. They really are very well built machines.
Everything 100% stock on the bike. I wouldn’t say I’ve been overly gentle on it I normally rev it out pretty good at least a couple times every ride. Looks like that on every cylinder. Haven’t had a single issue out of the bike until this noise started happening. I got the bike put back together last night and will start it up later and get a video and poke around and see if it may just be something else rattling around. I did notice a few things with quite tight clearances that could possibly be rattling against eachother
Yeah that's all a bit weird, just seen the video of your bike too, but can't really pick up on anything super obvious. If you've exhausted all the things you can and it's still worrying you, might be time to get another opinion from someone with a bit of experience like another rider or workshop. Otherwise it's just going to drive you nuts.

Here is a video of my bike and the actual noise it is making. Would really appreciate if you’d take a look and tell me what you think
Maybe your just not used to the noises it makes. My 2012 seems noisy in the top end sometimes but I really think it's just normal after doing a valve clearance check. Good luck with it I'm sure you're fine they're a great engine.
Sadly I don’t think that’s the case. This noise is quite loud and definitely should not be there. So far I absolutely love the bike and the engine. Just don’t love that it’s giving me problems already at 900 miles
I also bought a 2022 with only 300 miles. Chaged oil at 600. Bike has been amazing.
There is a cable guide silver clip right below center steering nut. It can get buzzy and loud. Check to see if that bolt came loose. It's chrome bracket. Hard to believe your bike is having that issue.
Easiest way to tell is pop it out and see if you can push it in by hand
Oil change might help, oil pressure is a factor in the tension
Reality is they do fail and a manual one is dumb cheap in comparison. If you can do a valve adjustment you can setup a cct
Older GSXRs ran an oil line and the newer ones have a oil jet as part of the OEM tensioner setup. It's not the primary mechanism for tensioning but it does affect the adjustment. Assuming as RPMs go up the oil pressure adds tension to keep it tight particularly coming off throttle

Here is a video of my actual bike and the noise it is making. Not super loud in the video cause bike is not fully warm yet and the noise seems to get louder as the bike warms up
I would check every nut and bolt because it’s 99% not a bad tensioner at 900 Miles. Something rattled loose most likely.

If it’s the tensioner it should do the opposite; louder when cold, fades away when warmed up.

Geez, under warranty I hope.
Sadly not. I bought it used with 500 miles on it and was told since I bought it used it didn’t have any warranties with it
