👌 excellent video and instructions. Short, direct, very easy to understand.
Is there any noticeable improvement in the sound and/or power?
Thumbs up and subscribed 🤝
Appreciate it, definitely a smoother delivery, noticed an enhanced crackle and improved acceleration.. overall gives the bike an unmasked feeling of de-restriction👍
@@motobolt7796 very helpful indeed. Are u planing to put it on a dyno to check torque/hp numbers and air/fuel ratio?
@@avrc9285 if it was something people were curious about I could make it happen and post a video
@@motobolt7796 I’m curious defo 👍
Can you share the Part number? Or link? I would appreciate it. I really want this air filter. Thank you.
This is truly one of the best single handed filmed DIY videos ever. Thanks so much!
I like how you're straight to the point, no padding BS.
Hello, I have cut the air box nozzles and I am very happy, now it is much smoother to open and close gas and the engine is now more linear, air filter and exhaust pipe stock ... thanks for the modification, when I got the Mivv exhaust pipe, I'll be happier .... Thank you ...😉
Thanks for sharing, great results even from stock.. you’ll love the outcome paired with your exhaust! Appreciate it😊
Nice! Is there a change in sound?
Something to be aware of! Doing this mod and exhaust mods changes the Air to Fuel ratio and back-pressure to the engine. A Tune is required to get the most performance and without could actually rob you of HP and Torque.
And ruin your engine by having it run lean.
@@josephfelice601 no it wont lol.
@@williambrewer855 At least explain why.
@@josephfelice601 it may run more lean than factory but not lean enough to cause damage. The 02 sensor in the exhaust will monitor exhaust gases and the air content within it. The bike will automatically adjust to a lean air fuel mixture and will add more fuel to compensate. Now if youre running no filter at all then thats when i would have concerns.
You guys are wrong, the mass airflow sensor is after the intake, it adjust fuel delivery depending on how much air it measures. If you would have a leak in between the mass air flow sensor and throttle then it would be a lean condition
Personally for me I will not be doing this mod. If i did it would just be the filter change and exhaust+ dino run. Cutting the plastics those tubes are perfectly sized for low mid torque power pluss less dirt crap to get into the aurbox. But good video on explaining how to get the tank of and airfilter out.
Nice job. Huge air flow improvement !!! Wow, can't believe how restrictive the OE stock intake was designed. Obviously designed that way to meet the Euro5 emissions rules.
Appreciate it! Yeah it’s a common air restriction to be euro compliant throughout the MT range
I love how engineers use all kinds of mathematics and equations to figure out the perfect length of these airbox runners just so some derpy joe blow can think he knows better and saw them off
Straight up dude. I was gonna do a full DNA air box and then found that When dyno’d it actually takes 1 hp away and just gives more mid range
This is the comment I was looking for! Exactly my thoughts!
Ya the reason I didn't do this modification, when I had the tank apart I noticed the air intakes were on the opposite side, top and also bottom, which probably means it's made that way to catch more dirt and debris, if you do this modification it seems like it will go right past the filter into the engine. 🤷🏽♂️
Yes much better!
Your comment does have some merit but also keep in mind when they are designing things, it's on the basis of legal emissions restrictions over anything else first. I can't say if this is a good or bad for engine health but I can confidently say I wouldn't bother myself. Any gains would be negligible best and more than likely just be moving the peak power elsewhere in the rev range rather than actually giving a real performance boost.
You alright mate you breathing pretty heavy take a break mate don’t want you hyperventilating.
More air flow means more power!
My 12 year old brain when I tried to attach a funnel to the carb inlet on my dirt bike
Thank you for your video. It was of great help when I changed out my air filter today.
Nice job friend. I hope you get rid of that ugly rear license plate holder next.
Very nice video. Why cutting the inlet trumpet? This will affect low and mid range torque in a negative way. You will gain at higher revs but that's not beneficial for fast roar use where you need low and mid torque.
Since you have interested the air volume by 57% you must adjust/add more fuel. Then you will have a noticeable gain from low all the way to the top.
It’s just cutting the intake snorkel which eliminates the maze of restriction just to get access to air.
Changing the height of the actual trumpets located on the battery side of the air filter is what will do what you’re suggesting here which wasn’t touched.
All we’ve done here is essentially taken a mask off while the bikes exercising👍
@@motobolt7796 well done :)))
@@motobolt7796 I just bought the same filter. I do have the same exhaust and i ordered from itally new ECU/fuel module with a wide band O2 sensor for better fueling. I will alter the snorkel but not in the way you did because we need to fill all the airbox with equal air pressure. by doing your way all the air will be sucked through the top of the filter instead of all the filtering area.
@@KHIJAPAN It’s not ram air like the Kawasaki’s, air pressure equalisers in the Airbox, it sucks as a whole through the air filter and not concentrated to one area as you suggest, it’s like suggesting a vacuum head is useless as it will only suck in the middle.. you’re increasing the CFM of air into your Airbox and available to your engine as the throttle body controls, allowing it to breathe unrestricted.
@@motobolt7796 not true. The intake snorkels are part of a finely tuned airbox system that uses resonance to move air with almost no resistance. The snorkels you cut off can be imagined as tiny ram-air inlets, in which the interia of moving air is used to suck more air through the snorkels, as the resonant frequency of the columns of oscillating air line up precisely with the pulses of high and low pressure created by the intake valves opening and closing. This is tuned to happen in a certain RPM range, usually around half of redline, as that's where most engines with valve overlap experience their strongest dip in torque. By cutting off the snorkels you have at best moved the resonant frequency to a less useful part of the RPM range, at worst (and more likely) removed the effect completely. In other words, by removing the snorkels you have actually added resistance to the system.
Interesting to see on a dyno run
Have witnessed the results in my experience but would love to demonstrate this one for you guys👍
Very good video! Thank you!!
Really curious if the bike is still running smoothly, especially since you also have an akrapovic exhaust. The air intake and outlet is a lot bigger now, but does how does fuel catch up?
Did you tune it with a powercommander-ish?
Or does it run any different (in a negative way?)
I heard somewhere that Large intake opening(s) narrowing down, thus speeding the air up.
You'd lose some of the ram effect by shortening the intake runner length...
Nice video. Very detailed. I didn't hear or see any mention of the sealing grease for the filter. Did you use it or skip it?
Ride safe.
It is safer to undo the other two screw at the back and rotate the tank upwards without removing all the way the front two screws ,in order to unhook the underside parts .So you'll not need a second person
The rear of the tank won’t hinge upwards without undoing the front ‘tank to chassis’ bolts as it’s flush against the mount of the 2 bolts at the back. You’re best bet would be to undo the front ones also, lift the rear up and over the mount and then reattach the front ‘tank to chassis’ bolts, now hinge it forward with and elastic strap to a garage crossbeam and then un-clip fuel line, plug and overflows tubes.. finally undo the front bolts and lift it off - one person job👍
@@motobolt7796 I insist that if you put back the two screws at 1:40 and put out the other screws at 0:24 you could lift the tank up from the back to undo the connections.
@@bill64gr my previous reply agrees but to be successful has to be done in the order i laid out.
Back of the tank won’t hinge upwards if you leave the bolts in at 1:40, the mount at 0:24 is in the way.
Only way to be successful, remove bolts at 0:24, remove bolts at 1:40, lift rear tank up and rest on top of mount, now re-secure bolts at 1:40 and now you can hinge tank upwards and disconnect tubes on your own
thanks a lot !!! from italy🇮🇹
thanks for the video, is this possible alone? Seems like you need one person to hold the tank, while anther disconnects the fuel line and two overflows?
excellent vid fella , i look forward to doing mine when the dna filter arrives , if you find out how it changes via a dyno , let us please . thank you
Appreciate it, your bike will definitely thank you and yes as soon as I can get to the dyno I’ll make a video👍
@@motobolt7796 cheers for replying , i`ve only done a 100 miles on mine due to our petrol crisis , look forward to having petrol and getting it run in
@@mididash hope it’s looking up for you, only gets better from there and after first service!
Thank you. I am Vietnam
Và bạn đã làm thử chưa?
Hi mate, theree will be no fuel leaking out of the tank when taking off the fuel line? Don't wanna have a mess xD
Nice video btw!
Crazy how much stuff you need to remove just to get to the air filter. Is it just me or is it a bad design?
It’s a shame you have to remove the cables and fuel lines, otherwise would be pretty straight forward.. ideal design would be the tank can just hinge backwards to reveal full access to the Airbox
it's more like a sports bike air box design, which the airbox sits under the seat, on my 890 the air box is more like a dirt bike design, it is under the seat and has an opening facing to the right side,
@@grumpybraincells6612 yeah it’s less than a 2 min job to change the air filter on a KTM 890, well designed and quick access
form over function if you ask me..!!👍
Very nice video ! Do you notice any difference in the fuel economy?
hello greetings, I would like to know if to remove the tank it is necessary to remove the fuel to avoid spillage of it when the fuel hose is removed.
Great video. I’m getting the Akra system but will hold on the airbox mod until local dyno tuning is available. I know that the this ECU was cracked recently. Very interested about the dyno with your airbox mod combined with the Akra system.
Congrats! I should have access to the dyno to bring you the results soon, it’s in the works and yeah Woolich has cracked it!
Hi great video, after to mod did the lamda speak to the ecu and correct its self or did you have to get it remaped
Cracking video, thank you for posting this 🙏
I've just purchased a DNA filter and I am about to have a go at tearing the bike apart as I have the bike going in for a full custom remap next week.
I hope you don't mind me asking but how long did this take you to complete from start to finish??
Any advice gratefully appreciated.
Many thanks and safe riding to you 🤜🏼🤛🏼
Not to worry mate, I've followed your advice and butchered the airbox lid this morning and fitted a DNA Stage 1 filter.
Didn't take long at all, about an hour so decided to fit my Ermax belly fairing as well. Instructions were, god awful if anyone plans on doing the same 😬
I've only got the standard MT09 but it's pretty tricked up now with KTECH suspension on the rear (Razor-R), stiffer springs in the front and a couple of grands worth of other mods (Carbon Akra etc)
Only thing lacking now is the Cruise control. I purched the clutch side switch gear last week and but unsure if this can be retrofitted. If you don't try you never know so keeping fingers crossed.
Had an interesting discussion with a friend who's had some long convos with a tuning specialist in the (U.K. of 26 years) and their message to him was:-
Hi ******, I have in the past tried AirBox mods and Air filters aftermarket. I have not seen much difference in terms of power outputs. I have not attempted to modify the AirBox on these as yet as looking at the way it is designed I believe that if it were to be altered we might be going backwards. Quite a number of motorcycle owners do actually realise that it is not the maximum power output figure that matters...its the way in which power is delivered, those are the numbers that prevail."
That being said I've got mine going in for a remap next week and the tuner im going to has just mapped another 2021 MT09 identical to mine without the Airbox mod so will be interesting to see the difference between the two.
I will try post up the results for any that may be interested 👍🏻
Thank you for sharing your knowledge and for imparting some things for us to do to our bikes 👍🏻
@@DBOLT666 hello, any update?
@@ADDONRACERfinally had the bike remapped and its completely transformed the bike.... pulls like a train now.
The original yamaha map was shutting off the throttles to 81% in 5th and 6th gear at 10,000rpm and I did previously notice this but didn't think too much about it.
Having the Woolwich remap is night and day different and has vastly improved the fuel air mix ratio.
My bike was running lean and now a lot better right down the line.
Regarding the Cruise Control retrofit I have decided against doing this unless I crash the bike..... 😔
Having studied the parts lists for both the standard and SP bikes and discussing it with my main dealer it looks like the bike will need a full wiring loom change (different part numbers), ECU and Key/Immobiliser, both side switch gears on the handle bars plus SP clutch lever. Fuse box is included in the loom part number but will require a couple of extra relays to accommodate the extra wires in the loom.
So personally im giving up on my quest to retrofit as it would be cheaper and far less hassle to just buy an SP.
According to Fowlers Parts UK the SP ECU is £955 alone (P/N BAM-W825000).
The main wiring loom £905 (P/N BAM8259000)
The switchgear + an extra small bit of loom (which I've already bought) has cost me £500, opposite side switch gear another £500
New ignition and key which will need coding to the ECU and you will also need the SP clutch lever as well.
It would be far easier and cheaper to just sell the bike and by an SP.
If you are considering a remap the Woolwich Racing remap is worth it's weight in gold.
I've just come back from 2 weeks of riding (from U.K. to the south of France, 10hours of riding each way as well) and the bike just gave more and more.
Brilliant experience 👍🏻
u helped me So mutch! thank you!!!!
Part number for the filter ?
Part number: P-Y9N21-01
And if you do the same with the stock exhaust, would you also notice that it works better?thanks
For sure, improved airflow doesn’t discriminate on exhaust choice
this 1 mod , have an impact at your driving ? you know , 1 mod keep you on kind of train rails ?? !
Cause averybody said how playful is the Tracer 900 and Mt09 ,but when i ride it , i didnt find it playful at all .
Now... this conclusion is falty cause the bike was set at mod 1 when i ride it ??????
Great video!!!
Appreciate the feedback, cheers👍
Thanks a lot man
DID filter need to be lube before instalation ?
Thanks for sharing.👍👍
Pleasure, many thanks 😊
Will there need to be a ECU flash or will the ECU be able to adjust correctly with drastic of a change?
Looking at getting myself a DNA air box / filter I was planning on getting a power commander as well would this be the way to go ?
Congrats! In the long run yes if you plan to get an exhaust system as well. Otherwise just the filter for now, and leave the power commander purchase and instal till after you’ve paired it with an exhaust👍
Power commander? What does it do? Enables you to tube your exhaust?
@@2jzRedLine it’s a little module that seamlessly optimizes your air/fuel ratio without directly changing the ECU, making it effortless to push it to the max. Easily uninstall to revert back to factory default settings when you feel like giving everyone else a chance
@@motobolt7796 that looks sweet. Still flashed ecu unavailable right?
@@2jzRedLine there’s rumours it’s been cracked by Woolich, but only rumours for now
Hi! How does your seat sit? Mine is abit looser on one side, is this normal? And is there a way to fix it?
There is a DNA stage 2 air filter aswell. Do you have any interest towards that?
Has the bike been tuned on the rollers after the mods? If yes, whp result?
Good video 👍
Hello what does the mods actually help with obviously more air flow but what else ?
In an analogy, it’s the equivalent of exercising with a mask on.. and this mod is taking the mask off 😷 better breathability, enhanced power and better acceleration with a side of sound improvement
Does it need a new map?
Did after cutting those plastics have riding difference ???
Tuners have already debunked this as not necessary. There is hardly any noticeable gain anywhere in the power band. Vcyclenut has a post about it on his website. Just food for thought. After reading his article, I’m not going to bother with it.
I did even more removal of air box lol it doesn't do anything if the bike is stock 🙄
Hi, great video. First (and only) one I’ve seen of a 2021 MT-09 tank removal. When removing the gas line from the tank, how do you disengage the clip/plug to then be able to slide it off. I saw you put it on, but not take it off. Thanks
Easiest way to describe the process is to treat it like a circlip, slide a small flat head screwdriver up between the closed side and with your finger unclip the left and right open side as you twist the screwdriver. It’ll unclip and free up the gas line to be pulled off like a plug.. hope this helps👍
@@motobolt7796 Thanks!
Is cutting of the tubes also creating more intake sound?
yes
Is this mod applicable for the new Tracer 9?
Hi do you know what the differences are between the SP seat and the stock seat
just the looks
How much weight saving does it make over the stock pipes ??
A Weight Reduction of : 2.6Kg
Power Gain : 4.5HP (3.3kW) at 9600 rpm
Torque Gain : 3.4Nm at 9600 rpm
Did you need to do any preparation to that filter like oiling it before installing?
I keep hearing .. with air filter mods u loose power!! Best thing for these gen 3’s is exhaust and a tune to remove the restrictions!!
Correct. Any gains through the intake side would be through opening up the head, where the bottleneck is actually occurring.
Hi may i know if the air filter is the same as tracer 9 gt?
Not the same being 2021, but for 2020 and earlier they’re the same across the models.. 2020 Part number for DNA or K&N is:
DNA: P-Y8N14-01
K&N: KYA-8514_3
I’ll be doing a performance air filter video on the 2020 Tracer GT this week👍
Good video, but
Result in drive!?
Better breathability, enhanced power and improved acceleration with a side of extra crackle
Different now?
Better breathability, enhanced power and improved acceleration with a side of extra crackle👍
Nice one 👍
So you have basically saved £300 on your mod.. instead of fitting the full dna air filter box 👍. I've got the 21 sp to..
@@DW-hx1xm congratulations, good choice 👏 yeah essentially only paid for the DNA air filter at $180 AUD
This way more water goes straight to the filter and has less of a chance to drain
Ahhh boss, you still have restriction with the DNA filter. You need a Sprint P08 filter. Absolutely unrestricted.
I had a look at them, but they only have half the surface area available in comparison to the DNA.
@@motobolt7796 not true. The standard P08 has equal surface area to cotton however with higher flow rate due to being composed of Polyester fabric and not using oil.
@@motobolt7796 You would be correct if we were talking about the P08 F1 filter which you can practically see right through
what does more air if you do not increase fuel...absolutely nothing .
Replace the intake trumpets and do a ecu reflash czcams.com/video/n8mMqjN8M1s/video.html We want a dyno test!
Tightening torque specs?
Where can we get this awesome airbox mod??
Part number for the DNA Filter is: P-Y9N21-01
The remainder is a little manual labour 😊
great video... also yours has the engine noise problem? like this czcams.com/video/LncPDQ-o1Iw/video.html it's so annoying
No I haven’t had that issue, just had its first service with 1500 kms on the clock and only positive things to report
thats plain stupid,it will kill your low ref power.
Lol, does the SP need MORE mid range !
