last updates : waiting for gasket order . then will check oil pressure by manual . maybe it's low pressure of oil ? (
On the left hand side, there are Book Marks in blue.there is just main page of manual , nothing else :/
Click on them to open up the Directories to further select the Volume and pages.
You navigate into the Manual through them.
If you don't have the Blue Book Marks shown, try using another Internet Browser. I am on Firefox clone, called Waterfox.

Did you ever figure this out? My bike started making the same noise recently, also only while cold.
My guess is it's an exhaust leak caused by header bolts being loose. There's a gap between the flange surface and gasket surface. Once the engine heats up, the gasket expands so the noise disappears.

I took the side fairings off and loosened the radiator out of the way to inspect the headers. The header bolts all seem tight. I didn't check that they were all 17 lb/ft like the specs say, I just used a hex key and checked that nothing was loose. But when I turned on the bike, the noise definitely sounded like it was coming from the front of the engine. Also I could detect a faint gasoline smell from the front of the engine. This suggests an exhaust leak even though the header bolts are tight, right? I am not sure what my next steps should be.
i didn't check exhaust bolts , but try to pull clutch when start engine ,try another oil with filter , chain tensioner ,still nothing .I took the side fairings off and loosened the radiator out of the way to inspect the headers.

i don't know what to do also .but it's glad to know that i am not the only one
i'm also worry about engine , but the problem seems not so big , because i was 3 times after this on track and pushing my bike very hard , and everything is fine , runs perfect . after cold days bike start make exactly same noise at cold start :/ please let me know , if you find solution.An interesting thread. From your first post you mentioned that the sound started after you put in Motul 7100. If that was the first time you used that oil, then I think the possibility exists that the problem is the oil.
Ive used Motul 7100 in a gsxr1000. I’ve found it pours like water, and my valve train was very noisy with it. I’m sure it’s an excellent oil, but my engine didn’t like it.
I had a similar problem with a Vfr750. At about 40000 kilometres I put in Amsoil 10-40, when previously I’d always used regular motorcycle oil. I did a short distance on it, and suddenly at idle, it started rattling. It was very loud. But if the bike was revved it went away and was fine. Then at idle it would rattle loudly Intermittently. If it wasn’t rattling I found I could induce it by leaning the bike from one side to the other.
I used a stethoscope and narrowed it down to the starter area on the right side clutch area. On examination I found the sprocket that connects to the starter motor had some play on its shaft, causing some side flex.
I went back to regular oil and the noise went away. I believe the regular oil being thicker, cushioned the sprocket on the shaft. The synthetic due to its properties enabled the rattle.
Now, as I said, if that was the first time you used Motul 7100, and are still using it, you might want to consider trying another synthetic, or regular oil.

first what i tried to change was oil , now i'm using castrol . noise from my engine come exactly from same area ( starter clutch , head , right side ) . but only in cold weather on cold engine . in summer even if bike was standing in garage few days , there was no noise on start time .An interesting thread.

I don't think it has anything to do with the oil. I also don't think it has anything to do with the transmission, clutch, or starter. My guess is still exhaust leak. My other guess would be cam chain tensioner, it would make a similar noise, but you said you turned the bolt one click and the noise remains.
My noise lasts about 1 minute on a cold start, then disappears completely. But I think my noise is not as pronounced as in your video, though it still sounds the same and I think it's the same issue. My bike has 50,000 kms. When I first heard the noise, I thought it needed a valve adjustment, but if your bike has only 5000 kms and makes the same noise then it's unlikely to be the valves. I am about to put my bike away for winter storage so I don't want to do any work on it now, but I might get the valves checked in the spring since they should be done around this mileage anyways.

yes i guess it will be exhaust ...my noise come only in cold weather , so i think it's cold metal of exhaust make this noiseI don't think it has anything to do with the oil.

i don't know i my country there is only 3 bikes like mine and no oficial service center , so i can't even get some experience adviceHere is a video of my bike making the noise: noise
Do you think it's the same issue or no? The noise sounds similar but not exactly the same.

i can't open video , do you have youtube link ?Here is a video of my bike making the noise: noise

cold whether comes , and noise on cold is come with it ! it's horrible !!! seems like something in engine needs to warm up little bit , then noise is gone ... i want to try to warm up headers with some warm fan , and then try to start it up , maybe it seems like stupid idea , but i don't know what to do .
have you sorted this issue?cold whether comes , and noise on cold is come with it ! it's horrible !!! seems like something in engine needs to warm up little bit , then noise is gone ... i want to try to warm up headers with some warm fan , and then try to start it up , maybe it seems like stupid idea , but i don't know what to do .
no Sir . noise is gone again after winter ends . still don't know what is a problem .have you sorted this issue?
I have the same problem on my gsx s1000f 2019 with 2k miles. Specially at cold and low rev only. I have an appointment at the dealer in the end of month. My friends think its the starter gear that doesn't disengage. Sorry my english i'm french
My listening to the sound via the link in Post 72 sound like the starter motor's sprag clutch lobes sticking. Oil being cold would add to it.
Here's an interesting tale from a BMW Forum on sprag, sprage, sprague (there's a few spelling variations) Starter sprag clutch failure.
There's a Member comment there that synthetic oil use, even though it's high detergent oil, allow's carbon to build up in the clutch race.
This clutch looks like a roller bearing, but the rollers are pawls which allow only one way of driving, and free wheel in the other (as when the motor crankshaft spins faster than the starter motor shaft).
Personally, I use base mineral oil, but I don't keep them for very long time. Change it often if you must if you are racing, a base mineral lie Shell10W40, and that's all the Suzuki Owners Manual asks for here.

My noise has disappeared. The first time I turned it on this year in March (after not running for 5 months over winter) it did not make the noise, and it has not made the noise any more this year. I am baffled but I'm glad the problem has disappeared for me. Interesting theory about the sprag clutch. I did use only synthetic oil (Rotella T6).
Did the dealer come back with a diagnosis and solution?I have the same problem on my gsx s1000f 2019 with 2k miles. Specially at cold and low rev only. I have an appointment at the dealer in the end of month. My friends think its the starter gear that doesn't disengage. Sorry my english i'm french
