#24 - KTM 390 Adventure | Unifilter Hack for Air Intake
Вставка
- Опубліковано 21 лип 2024
- I live in Japan and even getting your hands on a filter for the KTM 390 Adventure can take weeks and cost a small fortune in shipping, so changing it as often as recommend (or more often if you ride off-road like I do) can be costly and time consuming. In this video I show you how to lengthen the life the filter by installing a Unifilter prefilter, as well as improve the air intake.
私は日本に住んでいますが、KTM 390 Adventure用のエアフィルターを手に入れるには数週間かかり、送料もかかるため、推奨される頻度で（あるいは私のようにオフロードを走る場合はもっと頻繁に）フィルターを交換するには、費用と時間がかかります。このビデオでは、Unifilterプレフィルターを装着することでフィルターの寿命を延ばし、吸気口も改善する方法を紹介します。

![#27 - KTM 390 Adventure | Fuel X lite & Airbox Lid Install [UPDATE]](http://i.ytimg.com/vi/NpEqZQbVuH4/mqdefault.jpg)
Why not just install the DNA airbox lid? It bypasses all that snorkel and prefilter stuff.
Hey Dan, yes, became aware of this after the fact. A few other people have commented as well. If I go with the air box lid, what do you do with the snorkel? Just leave it there?
@@advinjapan yeah. Because it’s easy to return it to stock. Nah, just because I’m lazy😄
😂 Sounds like a win win, and the DNA is available here. I’ll pick one up next month a put out an update video. 👍 Thanks Dan!
@@advinjapan most people install a K&N in the standard spot. The lid doesn’t change the fact that the snorkel is still there.
Got it, very informative. 👍 Sounds like what you’re saying is the airbox lid provides so much more air inflow that it renders the lower intake (where the snorkel is) useless? I’ll pin this to the top. Btw, my fuelx is on the way as well 😁.
Man, your channel is so underated... Its very good! Keep it going!
Thank you so much. That’s the idea 😅
Thank you! I removed the cover, and now it breathes better. It cools down more easily, and I have more space for my wallet and other extras. have more place for my wallet and some extras
That’s great to hear! But don’t thank me, I got this from the BDSB channel, that guy is solid👍.
5:11 the red plug is the diagnostic port afaik.. you can get an adapter to a standard odb port like you have in most cars, then can plug all sorts of odb adapters in there, reading engine stats etc..
Hey thanks a lot, yeah I actually have now. This video was quite some time ago 🙏
Very nice 👍🏼 video. Thank you so much for sharing my friend . Keep safe always👍🏼😊🙋♂️
Thank you Jim!
Nice video as always. I’ll take a look at the tray removal!
Thanks Mak! Yup, simple hack 👍
I ended up just keeping the snorkel off. The inlet is before the filter so no worry of dirt. Now it pulls from a larger inlet up by the battery. I do have the fuelx lite, so im not sure if ecu changes are need. With the fuelx I haven’t had to change anything. Can upgrade the filter to a reusable k&n filter. So if you’re worried about the filter getting dirty faster the k&n allows you to clean and reuse.
That’s a good idea, thanks Bodyarmor! I will consider. Dang, I have to get me a fuelx lite, so many folks recommending it.
It’s been pretty nice. On the exhaust side I ended up cleaning out the resonator(mid pipe) and painfully gutted the rear catalytic converter. It’s made out of aluminum, so very difficult to try and drill/chisel it out. I’ll probably get a new header eventually to straight pipe it to the muffler. The fuelx has made this all possible with just a plug and play system. It’s a lot peppier and doesn’t lug down when you’re in the low rpm range.
@@SlyStrashMan That's a lot of work, you should record the process and upload it to UA-cam. I'd definitely check it out. Btw, noticed you're into lifting, me too man, five days a week!
@@advinjapan I thought about recording it but had no idea how it would turn out. It ended up taking me about 3hrs. Knowing what I know now i wouldn’t have fussed with the catalytic converter and would have gotten a new header instead. I got the idea of the resonator removal from one of ADV Matt’s videos.
5days a week working out!? That would kick my butt. Good for you though. I ended up doing those videos for the rogue 1000lb club challenge. Very strict rules, ended up failing it because my squat wasn’t deep enough. Keep up that motivation!
Thanks brother, you too! I’ve been thinking about making a video about key exercises to help with off-roading and to prevent injuries. I might contact you if you don’t mind and pick your brain a bit.
You explain things really well. Have you done a video on why you got this particular bike? I keep looking at it. What's the comfort like? It seems tall...I'm 5'9"... can you flat-foot it? Thx!!
Thanks! It’s a great bike. Very comfortable, though at highway speeds you will feel vibrations. I’m 5’11 and and I can’t flat foot it. They do sell a 2023 model with a lower seat. If you’re an experienced rider though and do mostly on road, I’d go with something larger and more comfortable.
My buddy is your height with this bike and he rides it fine. Can reach with his toes just enough to get by.
Nice! I've thought about doing this, but didn't want to take apart that back tray. Are you running a fuel mapper of any sort?
Hey iRide. Yes, I’ve got my fuel mapper coming in the mail. Though I don’t think a prefilter on the snorkel would warrant the mapper. But I’ve also decided to go with an airbox lid instead which drastically changed the air-fuel mixture and necessitates the fuel mapper. I’ll be uploading an update video here soon comparing the two upgrades.
@@advinjapan Nice. I ran the open airbox lid mod along with the Best Dual Sports mapper in Moab. Everything worked great until I went through a deep puddle. I think my mapper got wet. Had some strange electronic issues after that where the bike would run, but the throttle wouldn't work. Ended up taking it out and sending it back for a new one. I haven't put it back in yet... I'm not 100% positive something happened to the mapper, but its the only mod I could think of that might be causing issues. When you install put it in a plastic bag or something just incase.
That’s a bummer. Thanks for the tip, I’ll be sure to include that in the video.
Can you please throw some light about how to clean the unifilter
Super easy brother, soap and water. Be sure to relubricate with filter oil.
へ～Adventureのエアインテイクこうなっていたんですね。。勉強になりました。。
Hey Nokotanu! これは、エアインテークを改造するいくつかの方法のうちの1つです。安価な方法の1つです。インテークエアボックスの蓋を使うこともできますが、フューエルマッパーが必要になるので、少し高価になります。これについてはビデオを作成中で、近々公開する予定です。
@@advinjapan 興味津々動画アップ期待してます。
Nah, replacing the lid with the DNA filter is the best. You can feel and hear the extra power
Hehe, I love it too. Just slapped it back on yesterday.

I have coober airbox lid with a K&N filter atm. I might give that tray removal a try. See if I notice any difference.
I think that red connector is the OBD port, I remember seeing my KTM dealer plugging his laptop to that port. Not sure tho
Thanks Mok3r! Coober air box, I’ll will give that look for sure. And thanks for the info, sounds about right. I know the OBD port is back there somewhere👍.
@@advinjapan Its nothing fancy, just an airbox lid with holes in it and some foam. I’ve seen people 3D print them on the cheap.
That’s actually a good idea. I’ve got a friend with a printer. Might give it a go 😂
@@advinjapan make sure to use air filter specific foam.. regular foam might not filter properly and it's directly pulling ai into the airbox not through the internal air filter so a good filter foam must be used to avoid damage to the engine :).. there is an airbox lid available from BMC i think that uses actual oiled cotton filter like the aftermarket internal filters. a bit expensive but it might be a safer option and make sure you add some type of fuel injection ratio tuner like fuel X pro or a full on retune of ECU through a piggy back EU :)
Thanks Hari! Yes, this prefilter is legit filter foam. You’re the 100th person to recommend fuel mapper 🤣🤣. I really have to get on now😂.
Hello from India,
My views, no offence... So Two things I still doubt about..
Quantitatively - Even adding the pre-filter stage, is as good as not letting more air into it. As engine does not suck air but it opens up the valve to let more air in.
Qualitatively - dust wins no matter what, just prolonging the life of filter over Quantitatively is not a wise choice.
To me this was a more of an experiment and not some really good way of thinking it.
I like the way you explain things, so before execution maybe you can explain on what you want to do next and give some points like similar to Quantitatively and Qualitatively. Viewers will comment their views and your next video could be the actual implementation.
Thanks Sachin, no offense taken 👍. I appreciate your thoughtful response my friend and will consider your points for future reference. If I notice anything not working well, I will definitely post a follow-up!
@@advinjapan You are welcome. Will be awaiting on your current setup feedback.
Exactly, going through so much trouble for just increasing the life of the air filter?
At the time it was very hard to get filters here in Japan and they cost almost twice as much as normal.
