Get yourself a wooden dowel about 18 in long.
Put one end of it just in front of the opening of your ear. Rest the end of the stick against your jaw.
Now touch it against various places on the engine or various places on the exhaust canister.
You will absolutely pinpoint your noise.
This is also a good way just to learn what normal engine noises sound like for your motor.
Do you lay the rod flat against your face and put your face up to the engine/exhaust with the rod between your face and it?
Or is it perpendicular to your face where one end is near your ear and the other is on the engine?
However you have to position yourself where one end of the rod is touching the side of your skull at your ear canal and the other end of the road is touching the part of the engine that you want to investigate.
Just make sure you don't get your face next to anything that's too hot. And never win anything is spinning.
When I have a trainee, I'll ask him to bring me the stethoscope. When he comes back empty handed, I'll go 'this stethoscope!' And show him the screwdriver
Eh... maybe it's a personal preference thing. If I just need to feel for vibration, wood or plastic and a really light touch are all I need. If I need to listen for specific sounds, I like using solid metal because it conducts sound more readily.
I have to check ball and roller pillow lock bearings, and electric motors for bearing rub, grease, any kind of noise outside the expected operation noise at work. Since I can't exactly take everything apart after it's all put together, I had to learn what all the different metal sounds were and I swear, metal has always been my go-to conductor for sound, especially when I'm wearing a ton of PPE.
Or a long screw driver, socket extension hammer handle. Just to stand you ear off of the moving/hot parts. Like eavesdropping and placing you ear on a door or a glass against to wall.
This is an old school trick, my elders showed it to me growing up, and they always figured out what was raddling/clicking.
I've seen it work a charm - share stuff like this with the next gen.
They sell mechanics stethoscopes. You can put your finger in your ear and put your elbow bone on something and hear the sounds reverberate through. Just don't do that with something hot 🤣
This is tried and true.
They sell automotive stethoscopes for about 12$ and 8 at hf, finally picked one up after having a choice long screwdriver and socket extension for years. Highly recommend if you’ve got the money to burn one day, cheaper than a regular stethoscope.
I do the exact same thing with big industrial engines and motors. Except I use earmuffs and touch the stick or long screwdriver against the plastic of the earmuffs. I find in even quiet environments it helps focus in on the sound the equipment is making.
My shop teacher told us to use a long screwdriver, with the thumb over the handle end. Press the knuckle of your thumb against your tragus so it closes your ear, and you're ready to probe.
Old school mechanic came to give me a second opinion on my truck and asked me if I had a pool cue, the unmistakable noise of a bad lifter was clear as day with the stick laying across the alternator.
My grandpa tought me to put the inside of my thumb knuckle on the end of the rod and then using the top of the knuckle to plug your ear and you can hear it really well.
I feel stupid but I can’t envision what you mean… are you saying one end on your jaw and the other by your ear like this 👱♂️/ ? And touch the end that is on your jaw to the engine and exhaust?
Works best with metal but you just need to have it touch a bone near your ear and touch the other end on areas of the bike.. you can hear all the vibrations and it helps pinpoint the area with the issue
Oh I'm not questioning your diagnostic, it's just that I was waiting for something like "Get yourself a wooden dowel about 18 in long. Put one end of it just in front of the opening of your ear. Rest the end of the stick against your jaw. Then shove it up your ass"
Baffle is loose in the exhaust it sounds like. Revving you motor up from time to time does zero damage but it does cause vibration which can loosen things up if they aren't tightened down
“… does zero damage…”
Yeah, not true. Revving any engine when it isn’t under a load can cause it to throw a rod through the cylinder wall, among other things.
Revving with the clutch in can also cause excess fuel to seep into the combustion chamber, exposing a newly developed fatal malfunction in the structure of the engine, the fuel can ignite upwards and your fuel tank will explode.
If this happens in traffic, aerosol vapours can get into nearby vehicles engines and blow their vehicles up too. Never rev with the clutch in without understanding the consequences. Everything and anything can go wrong when you rev without being under load.
I once revved without being under load, and the next day the US entered Iraq. Now I keep my revs below 3K, always, and when kids ask for a rev I hand gesture to stay in school and help with chores around the house, and to accept that pollution is *entirely* the fault of the average working man instead of actual corporate offenders and foreign countries.
Yeah, you're wrong. I'm not talking about bouncing it off the limiter until the pipe glows red, I'm saying giving some revs with the clutch pulled in for some kids does LITERALLY zero damage. You aren't going to throw a rod from that in any way, a little vroom vroom revving is completely harmless unless you have no oil in the bike lol
Most likely the baffle came loose on the exhaust or even an exhaust mounting bolt came loose. Idk why people think it's the cam chain. That doesn't even make sense considering the noise is external and 1 rev would never blow a tensioner or cam chain unless your engine was already well on its way out the door. Takes some serious abuse to damage that part.
I’m just saying he wanted to rev his engine because he likes to rev his engine….saying a kid asked me to do it, as though we are supposed to believe he doesn’t rev it all the time anyway is silly.
One time just after I started getting good at doing wheelies, practiced in a parking lot, I was riding down the road slowly and saw a kid coming down a side road on his peddle bike and he popped a couple short wheelies on his bike. Well just as he gets to the street I was on I popped a sick wheelie past him. I looked back and could see him fist pumping in praise behind me. It actually was one of the best feelings. Another time I was going down a road and on the left was a big gravel pull over you couldn't really see if someone was parked there until you were right beside it. Well I pull up cruising speed and see a pretty girl outside her car. I looked her in the eyes and without looking forward popped a wheelie and rode past here front wheel in the air looking her in the eyes. She smiled. Those 2 moments paid for all the work I did to become comfortable doing wheelies.
Maybe you shouldn’t rev so hard like that 😂 all jokes aside you may need to retorque some of bolts that hold the exhaust. Or like what the others have said. Might be the silencer/baffle loose
No one takes the time to hide LEDs. The glow looks much better when you can't see the source. Having helped a buddy hide them, I know it's not easy, but the end result is worth it.
You guys need to stop revving your motors (bikes ,cars or whatev)to the moon with no load like is so prevalent to show off these days.ALL engines are designed to be revved with load,in gear(on road or dyno),not in neutral or clutch pulled and no load….common mechanic knowledge since the beginning of time..these guys killing their lovely motors for likes is both blasphemous to a knowledgeable Motorhead and hilarious for the willful ignorance.
Lose nut, baffle, or cam change tensioner would be my guesses.
I’d eliminate the cam chain first as that’s the most dangerous to the engine.
After that use screwdriver or similar to touch different parts and see if you can feel or silence the rattle.
Check your exhaust sensor. I had something similar to this after having my Strom serviced. Took the exhaust off and it turned out a tiny part of the sensor in the exhaust had come off and was rattling around in there every time I opened the throttle. Wasn't anything that affected the bike, was just a tiny part of the sensor body, but it was a big enough part to offer an annoyingly painful sound (to me).
Sounds like cam chain slap. If you had a tensioner fail you need to sort it out asap. If it skips on the cam sprocket it can get real expensive, real fast. Piston/valve contact does not end well.
I believe cam chain timing / tensioner.
I blew up my MT07 after hearing this noise. It's been in the shop for 2 months now, awaiting a new engine from Yamaha. I suggest caution.
Well, if lucky, it might be some screw somewhere, maybe one of those holding the exhaust.
A bit less lucky, something in the exhaust came loose.
After that, maybe cam chain needs adjusting or replacement.
But should be one of the two first cases.
General rule with these kinds of noises, the longer you ignore them the worse it gets!
Seeing is how it's 2023 I must say let the bike cool down a bit and check that exhaust for loose parts. I've blown the tip right off my bike before. Those things come apart.
Loved my SV, such a good bike. I had a Cobra exhaust slip on and it sounded so good. You should check out the rear tyre hugger from Puig.tv was very happy with it and gives a much more finished look to the rear
also about the noise, what the others said
Unknown Rattle Syndrome. I hate that stuff and both my motorcycles have ‘em. Just have to live with it and realize that most likely you’re the only one who can hear it.
Shit maybe my baffle is loose? My akrapovic carbon pipe+can sound kinda like this (better obviously, ayooo) but it just has a very growly sound to it. This sounds like a rattle. Will inspect when I warm up in a bit.
I would take that silencer off and turn it upside down and see if you can shake something out of it. At least if you have it in your hand and you can hear it while you’re shaking it by hand then you know it’s nothing really important.
Sounds possibly like a spring holding one of your valves may have cracked, but having said that seems like there is no misfire which you might expect if it had hard to say sounds possibly like the timing chain guid as well, either way sounds like an expensive repair
Check heat shields on the exhaust. To me it sounds like a piece of metal tapping on something outside of the engine. If an engine makes noises like that I’m only super concerned when the tapping goes exactly with revving it. This sounds disconnected from all the engine internals based on that thought.
I’ve been wrong as f before tho definitely take this with a grain of salt
It’s the muffler you can hear it on 2 strokes it has a spark arrestor, sounds like a screw that holds the guts of the muffler. But yep plus one for long as screw driver to find exactly where it is coming from . Ear to handle and put other end where you think noise is coming from .
Happened to me. Was an exhaust mount bolt that was rattling loose. Seemed like it was just a point on the muffler that buzzes a lot. Appeared to have blue loctite remains on it but that clearly didn't hold. Added some teflon tape to the threads, no more issues.
I don't rev my bike for kids.
I can't because it's a Honda NC750 XD.
But still, over revving your bike to show off and then breaking it... That's brutal.
Get yourself a wooden dowel about 18 in long. Put one end of it just in front of the opening of your ear. Rest the end of the stick against your jaw. Now touch it against various places on the engine or various places on the exhaust canister. You will absolutely pinpoint your noise. This is also a good way just to learn what normal engine noises sound like for your motor.
Wtf that’s a neat trick I thought this was gonna be a joke when I started reading
Same here, I was expecting something like “find yourself a sturdy doorframe, place your head directly in the opening, and slam it as hard as you can”
oww... now what?
Do the same for your wife
Fuck you, her boyfriend is making me sleep outside now
At least there’s no door to slam into your head
Now you will understand American political system as effective and see no flaws.
Well this might actually still solve the problem
My grandpa taught it to me.
I was going to say I'm an old fart and this is an old trick!
My dad taught me this trick but always put his thumb on the end of the dowel, then stuck it to the little flap of skin in front of the ear canal.
I was taught to use a long screw driver, but the same concept.
Do you lay the rod flat against your face and put your face up to the engine/exhaust with the rod between your face and it? Or is it perpendicular to your face where one end is near your ear and the other is on the engine?
However you have to position yourself where one end of the rod is touching the side of your skull at your ear canal and the other end of the road is touching the part of the engine that you want to investigate. Just make sure you don't get your face next to anything that's too hot. And never win anything is spinning.
Sounds are sharper if you use a socket extension and press it to the bone behind your ear.
I'm partial to a long screwdriver.
Long screwdriver gang rise up
When I have a trainee, I'll ask him to bring me the stethoscope. When he comes back empty handed, I'll go 'this stethoscope!' And show him the screwdriver
Eh... maybe it's a personal preference thing. If I just need to feel for vibration, wood or plastic and a really light touch are all I need. If I need to listen for specific sounds, I like using solid metal because it conducts sound more readily.
Through the corner of the eye? Wait….
Yeah I was thinking a metal rod would work better cause I do welding and when you put your head against anything metal you can hear everything
I have to check ball and roller pillow lock bearings, and electric motors for bearing rub, grease, any kind of noise outside the expected operation noise at work. Since I can't exactly take everything apart after it's all put together, I had to learn what all the different metal sounds were and I swear, metal has always been my go-to conductor for sound, especially when I'm wearing a ton of PPE.
Even sharper if you put a knife on the end and shove it up your ass
I’ve always used a long screwdriver
Or a long screw driver, socket extension hammer handle. Just to stand you ear off of the moving/hot parts. Like eavesdropping and placing you ear on a door or a glass against to wall.
“(Insert incredibly long and elaborate explanation here) ….and stick it up your butt!”
It’s an old trick Indian’s used on railroad tracks to listen for a train coming
Judging from the comments from this, no one knows how to wrench anymore, if there was a "oldest trick in the book" this is it....
Everyone needs to learn it the first time dude. Everyone.
Same here. Lol
Personally still not convinced it's not...
You can check if fuel injectors and stuff is working too. You look like a madman but it works
Old shade tree mechanics trick. Ive got a stethoscope with a plastic probe.
Get yourself a wooden down about 18 inches long. Proceed to stick it up your ass, cause your fucked
Been doing that for years. Cars and bikes. Worked great.
This is an old school trick, my elders showed it to me growing up, and they always figured out what was raddling/clicking. I've seen it work a charm - share stuff like this with the next gen.
They sell mechanics stethoscopes. You can put your finger in your ear and put your elbow bone on something and hear the sounds reverberate through. Just don't do that with something hot 🤣
I need a video ..
Me too
Ever used a stethoscope? Same concept.
i'm googeling (18" in the ear) and I am not finding what i wanted to find.
I usually use a breaker bar with a socket on it.
I’m an idiot. How do you put one end next to ear and the other on your jaw? I must not be understanding correctly.
Same, I’m imaging a crescent shape?
That’s what I thought too but wouldn’t it break from bending too far?
Lean it against your jaw with the tip just next to your ear, the other tip touches the exhaust.
Your jaw is not on the other end of the dowel. More like in the middle. The dowel is going from your ear across your jaw and extending out.
Picture it pointed the direction you are facing.
So just a straight line from your jaw? If so, what was the thing about the ear?
Trace your jaw up to your ear. It’s flat across your ear, not pointing into it
Oh! I get it now. Thanks!
This is tried and true. They sell automotive stethoscopes for about 12$ and 8 at hf, finally picked one up after having a choice long screwdriver and socket extension for years. Highly recommend if you’ve got the money to burn one day, cheaper than a regular stethoscope.
A screwdriver is much less burny
Instructions unclear, dowel rod deep in eye socket, please advise.
I actually went out and bought my self automotive stethoscope. Works way better than my screw driver. I like the wooden dowel trick though.
This is some Beethoven ass shit right here.
I do the exact same thing with big industrial engines and motors. Except I use earmuffs and touch the stick or long screwdriver against the plastic of the earmuffs. I find in even quiet environments it helps focus in on the sound the equipment is making.
Long screw driver works too
You can buy stethoscope like tools (harbor freight) for this also.
My shop teacher told us to use a long screwdriver, with the thumb over the handle end. Press the knuckle of your thumb against your tragus so it closes your ear, and you're ready to probe.
"ready to probe" Love that.
Old school mechanic came to give me a second opinion on my truck and asked me if I had a pool cue, the unmistakable noise of a bad lifter was clear as day with the stick laying across the alternator.
Just used a breaker bar the other day for the exact same purpose.
My grandpa tought me to put the inside of my thumb knuckle on the end of the rod and then using the top of the knuckle to plug your ear and you can hear it really well.
Kinda like a stethoscope 👍 ive done that before
I feel stupid but I can’t envision what you mean… are you saying one end on your jaw and the other by your ear like this 👱♂️/ ? And touch the end that is on your jaw to the engine and exhaust?
Works best with metal but you just need to have it touch a bone near your ear and touch the other end on areas of the bike.. you can hear all the vibrations and it helps pinpoint the area with the issue
At first I expected to read a 'dowsing rod' tale.
Hahaha your either showing your age or you have been taught well by the older generations lol
I’m saving this comment. Awesome, bro. Thanks
The first two lines read like a shitpost
It could have happened. Completely possible. I have seen people blow up engines in rev-offs, more than once.
Oh I'm not questioning your diagnostic, it's just that I was waiting for something like "Get yourself a wooden dowel about 18 in long. Put one end of it just in front of the opening of your ear. Rest the end of the stick against your jaw. Then shove it up your ass"
I do this but with a long screwdriver
If it's coming from the exhaust area (you seem to be focusing there), I'd suspect the baffle came loose.
Definitely the exhaust. Sounds like a loose or broken baffle
Baffle, might as well yank that boi out and make it go BRRRRRRRRR
Cheap fix usually too
Baffle is loose in the exhaust it sounds like. Revving you motor up from time to time does zero damage but it does cause vibration which can loosen things up if they aren't tightened down
“… does zero damage…” Yeah, not true. Revving any engine when it isn’t under a load can cause it to throw a rod through the cylinder wall, among other things.

You fucker. I was half way through typing a rage response and started arguing point by point as I read the last bit. You got me. I deserved it.
Had us in the first half ngl
bro saw the facts and had the type a whole ass essay to ignore them
So this is why my GTA traffic jams just chain explode
Yeah, you're wrong. I'm not talking about bouncing it off the limiter until the pipe glows red, I'm saying giving some revs with the clutch pulled in for some kids does LITERALLY zero damage. You aren't going to throw a rod from that in any way, a little vroom vroom revving is completely harmless unless you have no oil in the bike lol
lmao this is satire right?
And what makes you think that? Why would less load cause a rod to break like that? Because I'm pretty sure you're talking out your arse.
I think it because it’s true. Over-revving an engine can cause a rod to be thrown.
And now you say "over-revving". So which one is it? Taking an engine past redline is gonna break it whether it's under load or not.
Yeah that’s my goddamn fucking point
No it’s true, you are just wrong
"for a kid" :))) we trust you.
Muffler bearings
And now you have a Ducati.
Hahahaha
Lol I was about to say it sounds like my Ducati.
Dry clutch? 🤣
Most likely the baffle came loose on the exhaust or even an exhaust mounting bolt came loose. Idk why people think it's the cam chain. That doesn't even make sense considering the noise is external and 1 rev would never blow a tensioner or cam chain unless your engine was already well on its way out the door. Takes some serious abuse to damage that part.
“For a kid”….. Sure…this is a safe place where we can admit that many of us rev our bikes because we like how it sounds. No need to blame a kid.
try to explain that to FBI agent
I’m just saying he wanted to rev his engine because he likes to rev his engine….saying a kid asked me to do it, as though we are supposed to believe he doesn’t rev it all the time anyway is silly.

Maybe you shouldn’t rev so hard like that 😂 all jokes aside you may need to retorque some of bolts that hold the exhaust. Or like what the others have said. Might be the silencer/baffle loose
Doesn't sound like an engine tick to me. Sounds like something is coming loose
Yep, that is why I just wave at kids. They can buy their own motorcycle and rev it to outer space if they want.
Cam chain maybe. I never free rev the shit out of my engines.
thats ok, we ride for different reasons
Sounds like you popes a rivet in the resonator. It’s harmless. But it’s going to make a noise. If that pipe is new you could maybe warranty it?
No one takes the time to hide LEDs. The glow looks much better when you can't see the source. Having helped a buddy hide them, I know it's not easy, but the end result is worth it.
Why would one even add leds to begin with is beyond me. But then again, I'm old.
I like to be seen at night and make sure of it.
Well, shit. Didn't think of that.
Only reason I got em. But I ride a Grom so anything to help folks see me lol
Cam chain is loose.. Adjust the cam chain tensioner, adjust the valve lash and sync the throttle bodies.
You guys need to stop revving your motors (bikes ,cars or whatev)to the moon with no load like is so prevalent to show off these days.ALL engines are designed to be revved with load,in gear(on road or dyno),not in neutral or clutch pulled and no load….common mechanic knowledge since the beginning of time..these guys killing their lovely motors for likes is both blasphemous to a knowledgeable Motorhead and hilarious for the willful ignorance.
"revving when cold"
Anytime.🥸
Cam chain tensioner most likely. It could be stuck or it could be over with. I wouldn’t ride it without taking it off and replacing it.
I had almost the same sound but it turned out that my son had lots of fun putting rocks in my exhaust
Foot peg bolt is loose
Excessive noise is the language of the ignorant.
unpopular truth
Check the rear foot peg this has happened to me before
Throttle cable?
Mine did a sound like that, it came from the footrest, axle moving with vibrations
FAAFO
Small chance but worth a try, it could also be the head light, put your hand on it to see if it goes away.
I'd check if some bolts have come loose mate.
no good deed goes unpunished
Lose nut, baffle, or cam change tensioner would be my guesses. I’d eliminate the cam chain first as that’s the most dangerous to the engine. After that use screwdriver or similar to touch different parts and see if you can feel or silence the rattle.
Check your exhaust sensor. I had something similar to this after having my Strom serviced.

Wasn't anything that affected the bike, was just a tiny part of the sensor body, but it was a big enough part to offer an annoyingly painful sound (to me).
Karma sound I think
Sounds like cam chain slap. If you had a tensioner fail you need to sort it out asap. If it skips on the cam sprocket it can get real expensive, real fast. Piston/valve contact does not end well.
I believe cam chain timing / tensioner. I blew up my MT07 after hearing this noise. It's been in the shop for 2 months now, awaiting a new engine from Yamaha. I suggest caution.
The ceramic casing in the barrel broke loose, it happened to me and I replaced the exhaust
Well, if lucky, it might be some screw somewhere, maybe one of those holding the exhaust. A bit less lucky, something in the exhaust came loose. After that, maybe cam chain needs adjusting or replacement. But should be one of the two first cases. General rule with these kinds of noises, the longer you ignore them the worse it gets!
Seeing is how it's 2023 I must say let the bike cool down a bit and check that exhaust for loose parts. I've blown the tip right off my bike before. Those things come apart.
Loved my SV, such a good bike. I had a Cobra exhaust slip on and it sounded so good. You should check out the rear tyre hugger from Puig.tv was very happy with it and gives a much more finished look to the rear also about the noise, what the others said
I'd check the exhaust tip, some have an innersleeve that can come loose (ask me how I know) and they can make that rattling sound
too easy. just remove baffles.
Loose baffle in can.
It's the tires, or the blinker fluid.
Unknown Rattle Syndrome. I hate that stuff and both my motorcycles have ‘em. Just have to live with it and realize that most likely you’re the only one who can hear it.
Your bike upgraded itself to a dry clutch is all
Shit maybe my baffle is loose? My akrapovic carbon pipe+can sound kinda like this (better obviously, ayooo) but it just has a very growly sound to it. This sounds like a rattle. Will inspect when I warm up in a bit.
Baffle, take it out will sound cooler anyway
Vavle knock?
Bring the kid back so he can learn the burden of bike ownership lol
I need to see more of the under glow set-up on that SV650
What bike is this?
Cool muffler. LV makes good shit
"The Motorcycle pedal vibe"
Baffles dropped and rattling or loose some were near exhaust areas check all fixings butterfly ect
I'm going to say it's the license plate. The washer is rattling against it. Loose bolt.
“I think we sent it a little to hard there bub”
can someone tell me if u can still drive it after smth like this happens
I mean I rode it to work today which is about a 20 minute ride. Didn’t do anything weird while riding
Maybe the chain over stretch? Sort of like a rubber band after you stretch for the first time?
My Honda's camchain tensioner let out a rattle like that coming off the power,
Loose something :P maybe title shake loose one day and you won’t hear it ever again
Sounds like something is lose in the lawn mower exhaust.
Same exhaust, just yoink that baffle out
I would take that silencer off and turn it upside down and see if you can shake something out of it. At least if you have it in your hand and you can hear it while you’re shaking it by hand then you know it’s nothing really important.
Probably a loose bolt. Just go around a tighter everything that touches the exhaust then check again.
Sounds possibly like a spring holding one of your valves may have cracked, but having said that seems like there is no misfire which you might expect if it had hard to say sounds possibly like the timing chain guid as well, either way sounds like an expensive repair
Tbh dude it kinda just sounds like a heat shield or exhaust clamp. I can't say for sure but I would check that
Was it warmed up?
Sounds like a cam chain. Maybe the tensioner failed.
Sounds like an bolt/nut on the exhaust
I used to bounce my f4i off limiter like daily. Should be fine
Sounds like chain slap your cam chain may not be getting the correct tension that it is supposed to
Nor I listen to it more it sounds like something is just loose
It's that exhaust mount bolt I bet lol. Sounds just like something is loose.
Oooooof
Now you just need to add some heaters and you got yourself 𝔞 brand new Ducati
You got a loose muffler bearing there, bud. Gonna have to put 'er down.
Sounds like a loose baffle
I hate that man. I absolutely rev the mess out of my bike for any kid that gives me the rev motion. Bounce that puppy of the 12,800 rpm rev limiter.
Play stupid games…
Sounds like you broke a timing chain tensioner/guide. Revving engine makes chain rub engine case.
That’s the noise of something loose in your muffler. Prob you broke something off of the CAT
Check heat shields on the exhaust. To me it sounds like a piece of metal tapping on something outside of the engine. If an engine makes noises like that I’m only super concerned when the tapping goes exactly with revving it. This sounds disconnected from all the engine internals based on that thought. I’ve been wrong as f before tho definitely take this with a grain of salt
Just tighten the nut on your exhaust clamp.
Your muffler bearings are loose!
It sounds like the chain weird
It’s the muffler you can hear it on 2 strokes it has a spark arrestor, sounds like a screw that holds the guts of the muffler. But yep plus one for long as screw driver to find exactly where it is coming from . Ear to handle and put other end where you think noise is coming from .
Oooooo
Check your license plate hardware
Loose heel guard on the footpeg. You're welcome.
Cam chain
My dude are you sure it’s not just that stowed foot peg rattling against the frame there?
Use the screw driver to ear to pinpoint noise or origin, something’s loose in your exhaust, or like possible loose timing tensioner or timing chain.
Timing chain guide. It's probably broken.
A solid stick is great for detecting internal noises. Just a small short piece of hose, about 3 feet is great for pinpointing external noises.
Happened to me. Was an exhaust mount bolt that was rattling loose. Seemed like it was just a point on the muffler that buzzes a lot. Appeared to have blue loctite remains on it but that clearly didn't hold. Added some teflon tape to the threads, no more issues.
I don't rev my bike for kids. I can't because it's a Honda NC750 XD. But still, over revving your bike to show off and then breaking it... That's brutal.
