#27 - KTM 390 Adventure | Fuel X lite & Airbox Lid Install [UPDATE]

[@PhillyLS1]

Hey bud. I wanted to make a comment as I have raced for years and actually worked for/with an air filter company. Please understand I'm not "sniping" you or giving you a hard time. You said that the manufacturers sacrifice filtration for airflow. That's not correct. OEM filters sacrifice air flow for cost and ease of maintenance. In terms of cost, paper filters are just that... cheap. It's a compromise. Furthermore emissions factor in. What you're not mentioning is that aftermarket non oem filters (which you pay a premium for) use different materials that A. flow better due to said material and B. are used by enthusiasts that will take extra time to work on their machine. Two popular air filter materials are gause (K&N) and foam (Twin Air). Both have advantages and disadvantages but do not sacrifice particulate filtration for airflow. Due to the nature of the material, they flow better by their nature. Foam filters require more maintenance, are cheaper, but have diminishing returns. The particulates caught in the filter can not be completely washed out. Gause filters flow better and can be washed better but are inferior in sandy conditions without a pre-filter. I recommend HIGHLY taking that air intake pre filter off. As I stated you'll be blocking more particulate materials, but you're sacrificing airflow and more importantly air temperature. IAT's are crucial on vehicle without mass air sensors. Finally if you're worried about particulate ingestion make sure you're actually getting foreign material past the filter. I recommend using a borescope to see what your situation is past the filter. And AND if you are getting particulate ingestion, then it's more likely an airbox seal issue and not the filter. I hope this helps and I'm not coming across as a dick. If you look at my channel, all we do is race offroad. The can ams I race have a pre-filter on our cvt's and the first thing we do is remove it as in sandy races the dust build up super heats the cvt. It's better to blow out the cvt and change a belt then DNF a race or melt a belt. Conversely it's better to have a little bit of dirt in your filter than your fuel controller having to dump fuel and foul plugs due to an air restriction issue. I dunno, something to think about. I'm wrong all the time, but just some food for thought.

[@advinjapan]

Wow, thanks for the detail brother. And no worries, I’m very thankful when people correct me. I will definitely keep this in mind. 👍

[@interstellarguy]

An easy way to know if dust is getting into the air filter box is to apply a thin layer of Vaseline inside the air box. Check after a week to see if there is any dust.

[@PauldelRosario]

Good info, Joe. This channel is like a 390 service manual. lol

[@advinjapan]

Haha, that’s the idea 🤣

[@RonOrud]

Great video. I love my FuelX lite. I put it on with 24 miles on the bike. I am half way in on break in mileage. I can’t wait to feel the full force after break in. They say the power jumps up after the service.

[@advinjapan]

Really? That’s interesting. I just took my bike out yesterday…unbelievable difference. The lid filter is definitely helping out as well. Will be uploading shortly.

[@Ntmoffi]

Does the bike automatically change around that time or no? Or does your dealer have to sort of "unlock" it for you?

[@RonOrud]

@@Ntmoffi I hit break in and did the service and reset the light, no difference that I noticed, but you doget the higher revs/more power. Maybe that is what everyone is talking about?

[@edvul]

Finally installed my fuelx thanks to this video. Also had to lift the tank the cable was way in there. Cutting a few zipties helped alot. Very easy job and the results are noticeable. Its a big improvement i dont have to downshift as much and it feels very smooth.

[@advinjapan]

Yes, one of the best upgrades I’ve done for sure. I agree with the smoothed out low end. I’ve actually started the bike in 3rd gear 🤣.

Fantastic video as usual, nice demonstration of the impact of using the airbox lid filter. I suspect you'll notice a big difference with the airbox lid filter but curious how you feel about the sound.

[@advinjapan]

Thanks a lot! I absolutely love the sound. But it can cause a lot of vibration under the seat so for longer trips I will put the OEM lid back on. 👍

[@tsdmoto]

@@advinjapan Do you feel the snorkel mod is worth it if you didn't want to go with the modified lid?

[@advinjapan]

@@tsdmoto it's dependent on where you live. In very dusty areas it's a must. If not, then it doesn't add much of anything. If you go that route, be sure to clean that thing often or you could restrict airflow.

[@JJPsyc]

I just installed the DNA lid and TuneX Lite. Seems like smoother throttle response down low and perhaps a bump in the upper mid range. Definitely a throatier intake sound when accelerating.

[@advinjapan]

Completely agree, the throttle honk is a lovely sound. Any overheating issues?

[@JJPsyc]

@@advinjapan I didn't ride for very long after the install. So far no overheating. I live at high elevation so it hasn't been very hot, so far.

[@advinjapan]

Hah! Oh man, I spend any more on this bike and my wife will leave me 🤣🤣

[@TheBigBlueMarble]

The issue that I see with adding an airbox lid that includes a high-performance (i.e. high flow) filter is that most air is then bypassing the main filter. Start the engine and check the amount of air actually flowing through the snorkel. It is probably very little.

[@advinjapan]

Hey, thanks for the comment. If you watch the entire video you’ll see that I demonstrated just that with a feather.

[@The101damnations]

Hey BigBlue, I see you on almost every Husqvarna/KTM video. I'm curious what setup you are running on your bike? Aftermarket air filter? FuelX? Powertronic?

Hey man, nice vid thanks. I live in Japan too and ride a Vitpilen 401, which has the same engine as your KTM. I bought the DNA and K&N filters on Amazon, should be arriving soon. Couple questions: (i) Where did you buy you FuelX Lite? (ii) are the filters & the FuelX Shaken proof? Keep it up!

[@69sled]

I ride a 2016 gen 1 duke 390 here in JAPAN, I replaced the Air filter and added the open lid mod to the bike, and I eliminated the snorkel. Currently going to change the sprocket and add an MSD ignition, and a rekluse Torqdrive clutch. This bike is perfect for running around considering how ridiculous the traffic can get around here in Japan. Fuel X is next after all that, thinking about changing the Airbox and maybe the injector?

Hey, nice to see someone else riding here. Damn, that’s a lot of work (and money🤣). Good luck dude, let me know how it goes👍.

[@amalantonyabraham]

You should take extra care from now on while riding in rain and when washing the bike. There's a great possibility that water could enter from under the seat. I suggest that you use the stock airbox lid for those conditions.

[@advinjapan]

Thank you for heads up Amal, and very good adobe indeed as the DNA filters do not catch water. 👍

[@virajvrooms]

Did this install today referring your video. Thanks. However, after the installation I have ridden the bike for a few kms. Not noticing any remarkable difference interms of low end torque or smoother quickshifting. The throttle response however has improved marginally. Wondering if the the unit is supposed to tune itself over a period of time 🤔

[@advinjapan]

Have you had your first service? I also have hear it does take some time for it to adjust to your riding. It is perhaps most noticeable if you use it with a a filter upgrade (stage 1 and most with stage 2).

[@virajvrooms]

@@advinjapan Yeah. I have completed 3 services already. One had the KTM firmware upgrade as well. Mine is the late 2022 version. I suspect they got rid of the issues to some extent on the latter versions. Hence the difference might not be noticable. I will monitor however. My next job is tho install the aux lamps and then tucking the Veridian Cruise module inside the headlamp unit. Again. I am referring your videos 😀

[@advinjapan]

@virajvrooms nice! I recommend splicing in water proof connectors on your aux lights for quick removal when working on the bike.

Hey Stephen, it’s been near 100 degrees with 80% humidity here lately. Just haven’t been able to get on the bike. It’s coming soon though, I promise👍. Just to give you an idea, fantastic smoothening in the lower gears with a bit of added power as well.

[@arunbabu6524]

Have you faced any issues with water creeping through the lid air filter ?. I tried a pressure wash with the stock air box cover and i could see water on top of the lid. What changes have you made to cope with the situation ( rain riding) ?

[@advinjapan]

Hey, thanks for the comment. I too have done pressure washer tests and a small amount of water makes its way in the pillion seat area. I’ve never had water in the filter itself. I actually don’t use this filter on long trips because of the risk of rain. The only time I use it is when I know I’m going off road, close by and the weather is good.

[@arunbabu6524]

@@advinjapanI found your mods very interesting and I bought a BMC air-filter and i came to know that before installing the lid filter, it is recommended to use a fuel injector controller . So i bought the newly lunched fuel x pro plus which is claimed to have increase torque by 25% on par throttle. I tested the product extensively and i found no difference in performance. Without fuel-x , fuel-x mode 1, fuel-x mode 3, fuel-x mode 8 and fuel-x mode 10 . Has same idling RPM. Same speed at 4k RPM at 1st,2nd and 3rd gear. Same speed and similar knocking issue (at identical rpm) on no-throttle at 1st, 2nd and 3rd gear. I contacted the support team and as per them fuel-x is working fine but they are unable to explain why i am not seeing performance difference. It would be great if you can do a video on with fuel-x and without fuel-x performance difference on closed loop. Is it really making a difference or just an illusion ?. I cannot find a video on youtube where influencers technically comparing with fuel-x and without fuel-x.

[@advinjapan]

Hey arun, thanks a lot. That might be something worth doing. I do have a reader now so I can see diagnostics. 25% seems a bit out of the realm of possibility. I think the biggest gains come from using it in conjunction with after market filter. Stick around and I might do something like this for you.

[@advinjapan]

This is great Sachin, thanks. Though the stalling issue is not necessary isolated to one single problem. The spark plug has also been a related issue, as well as pinched fuel lines. Finally, rider skill needs to be considered as well. The 390 has a very fast rpm roll off when cutting the throttle, which can also stall the bike if you aren’t feathering the clutch or downshifting properly. I feel like a lot of the stalling “problems” could be avoided simply by managing the clutch/ throttle and gear shifting better (myself included 😅).
