Feeling childish!
How to make a motorbike backfire.
1. Ride along
2. Hit the kill switch
3. Twisty twisty the throttle
4. Kill switch back on
5.BOOM!!
Do not do this on a corner!
I take no reasonability for you doing this! Im just showing you how it works! _____

I just wanted to let you know that aussies call this "Keybanging"
Thought you might get a kick out of that ;)
For those who don't know; How it works in a nutshell.
Roll along at speed, fuel is ignited by spark as normal.
Kill engine with switch, spark dies but fuel keeps entering cylinder(s)
Turn switch back on, spark ignites extra fuel, causing a backfire and sometimes flame.
Actually you just described afterfire and not backfire
This works just with carburator and old injection motorcycle. Today if you press the kill switch it will stop the fuel inition
This is what happened in my Honda Xr 200 i don’t even know how i did that.
@@marcopozzi522 well that’s a lie 😂😂😂 New mt07 and r1 can killswitch flame
Can’t this damage bike?
That's one way to get driver's off their phones..
how many came here after Time's Square?
David L x- me!
no stuff sherlock
Had to hear an example of what it was exactly lol
Was curious myself
Same. Just saw it on inside edition.
Do that while driving buy the local police station. lol
For the most part yes, however it is possible with injected engines, but the engine has to be pretty run down. The 'backfire' of an injected engine is usually more of a cough and splutter as the revs are coming down, I get this a lot on my V-Twin 750 Aprilia. A satisfying sound!
Don’t do this in New York.
*PTSD Intensifies*
😁😁
i figured this out on accident didn't realize i hit my killswitch and bike was slowing down, saw it turned it back on and BOOM super loud bang, since then ive done it maybe a bit too much. its so fun hopefully it doesn't hurt the motor because i defiantly abuse it.
It may lead to excessive wear in the exhaust system and ever so slight damage to the baffling in the exhaust, but otherwise no, it is perfectly safe on the bike so long as it isn't done too often (:
My bike don’t do it
@@tomking518your doing it wrong mate
someone in the comments said it depletes the life of the kill switch... thats wrong. at the MSF course they teach people to use the kills witch just to turn the bike off so its pressed like 100 times a day and those bikes have tens of thousands of miles on them. its good to use the kill switch every once in a while to prevent corrosion and make sure it still works incase you need it
But not in gear, you know
100 times is overly exaggerated
Fluttershy Ryan it’s used by a lot of different people in a day. Totally possible.
You only need to use the kill switch if in a emergency... thats why its called " kill switch"
@@JDMz Atleast we were taught to use it as a engine turn off switch, else every time i turn the key on, the fuel pump would keep running every now and then..
@JamesThyCool you need to give it a couple of twists of the throttle then turn it back on!
Also I don't have the standard exhaust!
@JamesThyCool as i understand it! it dose no damage apart from the chance the massive pressure in the exhaust could damage the exhaust, say its rusty and has a weak point. It could blow a hole! I have heard about someone blowing the baffles out! lol If your exhaust in in good condition then I think the odd one is ok! Just don@t keep doing it all the time! I have not done it for months and months until now!
how much will it affect our bike??
coz i used to do this alot ...
just love the bang sound on my bike😍😍
Its notoriously called ignition cut. Witch basically after a while affects oil pressure. Witch will then cause ring land failure. Then boom. Your engine has shit itself
you turn it off for a second or 2! when you turn in back on! bang!
Do you use move the throttle anymore or do you let it go
@@dragoshuen 7 years ago
@@UraSausauge way to not answer the question
@@MrPotatoAdrian yeah, maybe he got shot or hes in jail
get a pipes with no collectors and it will backfire when you let go the throttle
sorry to bother but whats a collector?
Ebin :DDDDD He meant katalysator in the exhaust pipe. katalysator's job is to get some of the gases that are going out of the exhaust to go back to the machine...
It wont, unless your valve timings are misadjusted or the carb is running rich
@@sorrow_rr *catalytic converter
@@jellystick2525 most motorcycles now don’t have carbs and are fuel injected
Prolonged usage will put wear and tear on the ignition, and if you have some poor quality exhaust, there is a chance it might split, apart from that its completely fine
this was the very first video of urs i watched whrn u first put it up haha
Haha been a while then! :-)
+spicy110 yh 3 years of awsome content man keep it up maybe i will make it to one of ur rides one day now i have a 125 cc
Does this affect the engine ?
No. Its safe. Its when unburnt fuel enters the exhaust pipe.
First ever video to start at Tescos!
yes it is bad for any vehicle , it can split exhaust seams , but the fun aspect is undeniable !!
It can more damage than that. It can play havoc on oil pressure and cause ring land failure
@@JDMz why do you keep saying this?
@adrenalynejunky Well thats a matter of opinion it seams! This is just saying how its done!
Here's the general rule of thumb with 2t's.
If it broke, you weren't riding it hard enough!
If you hurt it, you STILL weren't riding hard enough!
If you're winning, you're almost riding hard enough.
If you hurt yourself, you're riding hard enough.
Joking aside backfiring is like farting while you're pooping, it's just a funny and loud surprise. Also, I wouldn't worry too much about hurting a 2t. They were meant to be ran hard and are insanely cheap to fix.
Why is that so amusing?! Haha
watched this vid way back, recently subscribed to you and found this. didnt think it was specifically you. gd stuff. you must do this once again whenever ur next vid will be 👍👍
or you go buy a large displacement bike and just close the throttle and let the momentum keep the RPM up and get those same pops just A LOT LOUDER
Lol, look what appears on my you tube feed this morning. Such fun. Cheers Spicy
0:56....almost a Straight Through gearchange. Love it.... 🤣🤣🤣🤣👍👍👍👍👍👍👍
It's actually an afterlife. Backfire occurs by intake which is really bad , after fire occurs by exhaust which isn't good for bike either but not as damaging
Yer in the UK the terminology is interchangeable to the layman.
Yes how ever my childish side is about 95% of me! lol
I have a little pocket bike i do this on, it has a little push button kill switch that i tap really fast and it does the same thing. I wanna try this on my KX250 soon. The main secret to doing this is high octane gas and rpm, and a good kil switch.
i tried this with a cop...didn't work out very well
You could also just rev and hit the start at the same time on some bikes
no the engine needs to run on compression
Ehm.. I don't have a kill switch on my CBR 125R, can I still do this by turning on and off the ignition?:o
No
Yes.. I just did it on my yamaha lc135 on a stock exhaust.
This makes hell of a noise on a 50cc 2-stroke too xD Tried it...
Until the oil pump shits itself😂
By the looks in the comments, most people don't know that the kill switch is directly connected to the key ignition. The only difference is that the kill switch just stops ignition the gasses in the cylinder, while the key ignition shuts off all electronics on the bike. Also the myth that using the kill switch is bad for your bike, is actually just a myth...
It should work with every bike that has a switch for either breaking the circuit or just breaking the ignition circuit. If you do it right, you should be able to do it with a 50cc moped.
So you turn on the kill switch and then quickly turn the kill switch off while giving it gas?
Is this bad for the bike?
Shouldn't hurt your engine,
All your doing is turning the spark off and the unburnt fuel goes in to the exhaust...
Tho you may get a hole in your exhaust if you do it when the pipe is cold or old or if it has a weak weld from the factory....
does this work on 2-strokes? and will it do any damage on 2t?
yeah it works but u have to have very high revs and rapidly turn the killswitch on and off, it really doesnt cause damage because theres no valves, as long as you dont do it for too long, u probably dont need this info anymore but yeah
I really wanna do this, but im unsure if it’s dangerous
No cat delete required?
Awesome! ima try this!
@TimbeMovies maybe depends what it is!
Can the backfire happen repeatedly?
Not with this method However the most common way it happens and what probably happened in New York is a large cc bike reviewing till it hit the limiter with some bikes you will get what will sound like rapid gun fire.
@@spicy110 TY.
@@spicy110 that's why everyone is here I got a 250 quad and a 300cc quad will this do the trick the 300cc been parked so just reving it makes it pop
It works 😂 even on my factory standard exhaust..
no because mine is kickstart only as well and the momentary kill in the engine is not enough to kill it to the point that it need to be refired it will run if you unblock the connection (the kill switch) within a second or two
what about this video again on derek ;)
I'm sure you can do this on a bike without a kill switch. Switch the engine off, pull in the clutch, twisty throttle, turn ignition to "run" and pull out clutch in 2nd gear, bump starting the bike and making it backfire. I think.....?
hahaha love it!! loud and proud lol
So you just flip it on and off real quick!
Backfire is when flame shoots out carb what you are doing is afterburn
this is going to be one of my shortest videos ever 10 months later beats record by 51 seconds
It won't work on every bike. The bigger the carburetor, the more unburned fuel goes through the cylinder, the bigger the backfire. With smaller carbs (and smaller capacities) it is not so likely to work.
Does your hand stay on the throttle while doing this?
This is actually called afterfire and not back fire. Backfire is bad for your bike and potentially dangerous.
What was explained in this video cannot damage your bike. Afterfire is when unburnt fuel enters the exhaust pipe and sometimes occurs in cold temperatures, like winter.
Not going to fully agree there, if you do this a lot the pressure can damage the valves. "key banging" as this is also called creates much higher pressure than say a over run pop. also if you have bad rust on your exhaust pipe or can, it can blow holes.
Do You Have To Keep Some Throttle on or do you use no throttle when u hit the kill switch???
Do you have to pull the clutch while having the killswitch turned on?
Leo Leimgruber no you don’t
i tried this out before watching the video and it freaked the sh!t out of me
@spicy110 Ok dude i can do it perfectly now. Omg it is hilarious and sounds awesome. Only thing is im concerned about damaging my bike, you have any idea how bad it is for it ? thanks
Don't forget to hold in the clutch before hitting the killswitch, unless you want to slip 'n' slide. Or... are you not suppose to do that?
If you pulled the clutch in it won't work. What hitting the kill switch dose is pump unburnt fuel in to the exhaust and starting the bike by hitting the switch back on while still moving ignites this unburnt fuel. That's why this only works on bike with a carb.
I know it pumps unburnt fuel into the exhaust, but from my quad riding experiences if the quad catches traction while pushing it and turning it into gear it starts the engine, and the point is, where I ride you can't get alot of traction like the roads. So hitting the killswitch back I figured would do nothing, but the rear tire would lock up, and slip, if it get's traction, start the engine. But I guess I'm wrong, somehow hitting the killswitch back ignites the engine. Interesting.
Do you have to hold your clutch in cause surely if not your back wheel will lock up?
I have a 92 FZR 1000 Exup and I did it a couple of times worked pretty good
Legend!
So just hitting the kill switch off and back to on position makes it do that? How. Switch does nothing unless he means press kill switch back on like trying to fire bike up
I dont get it you need to let the bike get on again without touching the starter
Isn't that after fire, back goes back into intake
Put it this way, a friend of mine shot his exhaust off doing this lol.
Thats because its old, just like old people. They also can burb, but they always burb somthing up aswell!
Found out that if I just hold the throttle as is and flick it fast then it works.
Don't work for me got new bike, but when I let go the throttle you can hear backfire but not very loud need sport exhaust I guess
i learnt something new today :)
lmao you should go to the place that sold you the drift and make ya bike backfire that'll shit em up lol
헐ㅋ진짜 총기소유가능한 나라에선 총소리로 오해할수있겠네요... 우리나라였음... 누가 폭죽터뜨리나 했을듯
my bike just does a light burble when i hit the kill switch and then goes on as normal no backfire
Do another one of these on the Sinnis? :)
Nothing can happen to the engine if you abuse this? To break something in time?
most off all 4strokes with kill switch,i have a suzuki gn125 & make backfire every day,i like it.
i know this sound noobish but when i try this do u has to be in N or in drive without holdng the clutch? cause when i tried i was in second gear and pulled the clutch in when i turned off the bike when driving
LOL i know and these people are awesome!
I own a little 250cc honda rebel, it has carbs and I tried it yesterday
Did it in high and low rpms, ranging from a second wait to 3 seconds of waiting, and with and without pumping the gas.
Sadly none of these made it pop like it should, and I cant seem to figure out what I'm doing wrong, any ideas?
Exhaust?
Fuel injected?
does this work on all motorcykles?
so u just drive along, turn of the bike with the kill switch, blip the throttle a couple of times, and when rolling turn on the killswitch again and bang?
have i got it right?
This works for carb bike only I think. Because a fuel injection bike has to prime after you turn the switch back on.
Also, I've been told this puts holes in the piston if you do it too often? is that true?
+Kimberley Hughes No, the only stress it puts is on the muffler.
does not work on fuel injected bikes
Omg ive gotta do this when i get my sinnis! haha just line up next to a ped and do it >.
Is It luodest when you're riding the bike or when you are stop?
@spicy110 Ill give it another go tomorrow and oh yea the exhaust may make a difference. cheers anyway !
When you switch it off, do you switch it back on and then pull the throttle. Or do you switch it back on whilst pulling the throttle or after?
Just switch it on. Rpm has to be high though. But don't over do it. Its expensive engine rebuild once you blow the motor
he'd have to kickstart it to get going again
can't do this, i have a kick-start only bike
Just out of curiosity, does this also work with quad bikes? Like can I be rolling at speed, hit the engine run button off, blip the throttle, turn the engine back on and BOOM? Or is it safer to just rev it in neutral until it pops because that works too...?
It's best not to tbh, however this will work on any engine that uses a Carburettor. This will not work on fuel injected engines. The meteoth is as described in the video. Your risk do not advise haha but can be funny
@@spicy110does it work on 2strokes?
I wana get a bike to try this :D But also for the joy of having one too
0:41 🤣🤣🤣🤣
@Kawajedi HAHAHA! In the US by chance?
Dose it work with doing it with a key if you don't have a kill switch
you dont need one, i used to make my c90 backfire by rev high in second or third, as the engine slows down after you drop the throttle, turn ur key off and on a couple times. Just not on a corner.. lol
Thats down to incorrect valve clearances lol
You can just keep it in gear and than do the killswitch right? Or do you first have to put it in neutral?
In gear. But don't do it to often. Expensive engine rebuild
So you just kill it and turn it back on fast?
I didn't get it, for ex: I'm riding around passing gears, then i throttle up to raise the revs , then i turn off and emiatly on the kill switch while throttle on the same time?
Top tip. Dont do it. Expensive engine rebuild
I have the same bike and I cant do it :( it just spits quietly..
Would this work if you turned the ignition off?
and costs like hell...
