KTM 390 Adventure Part 8 (Coober headers, fuel x lite, K&N filter, DNA airbox lid, t-rex skid plate)

[@matthewkopf6243]

Haha! this guy looks like me! I've got the 390 ADV and Svart 401, and still always eyeing a RC 390. Not sure why I'm drawn to all the bikes with the same engine. I also have the T-rex on both bikes, had to do the same exact hack on the 390. Thanks for the video!

[@SeanFillner]

The motor is fantastic and more than enough power for any rider. I really love all of these bikes. They are so much fun. Stay tuned, more content to come....

[@realzeti]

Love your updates, based on which I have made bunch of updates to my bike. One last update which blew my mind was replacing stock exhaust with Dominator HP1 (which is on lase now), I thought you may be interested as the sound is amazing and since you already have FuelX, it will do fuel remapping for you. Great job, and thanks for sharing

[@SeanFillner]

I will look into this. Thanks for tuning in.

[@lindsayfinger4262]

Did notice any power and torque difference with the Dominator full exhaust?

[@sdefiel3719]

Staying tuned. S

[@bradsmalt3852]

FMF use to make a similar muffler design called fat max or something similar I don't think supertrapp has the oval style like that.

[@Dani-hh3qd]

Is the FuelX plug and play? I just got a Dominator full exhaust line and it doesn’t seem necessary but I do want to improve and slightly tune it. Does it come with pre installed mappings or do you have to tune it yourseld?

[@SeanFillner]

I covered the fuel x lite autotuner in depth in all 3 of my bike build playlists. Thanks for tuning in!

[@bobberbear4622]

does the t-rex skid plate mount to all stock locations directly on the motor or are there some additional mounting points that help make it more robust? comparing the blackdog vs the t-rex currently

[@SeanFillner]

The pdf install file is available at the t-rex website. That might help answer your questions.

[@joshg8446]

Well how did it run after the coober and the fuel X? Was it worth it? Noticeable change?

[@SeanFillner]

All 3 of my bikes run SOOOOOOOO much better with the fuel x lite installed. Just that mod alone is worth its weight in gold...

[@andrewtreloar7389]

hey Champ, understanding that you went with the Coober header why did you choose the X-Lite over the Coober ECU? Was it a matter of cost or is the X-Lite a better unit???

[@SeanFillner]

X-lite is the only one that autotunes for all future mods.

[@andrewtreloar7389]

@@SeanFillner makes perfect sense then!

[@rays9033]

Only the Coober will retain the KTM factory or extended warranty, correct?

[@andrewtreloar7389]

@@rays9033 really? I thought KTM would not warranty any of them!!

[@EnriqueHernandez-pb3zq]

You mention giving time for the fuelx to calibrate, is this a first time thing or do you do this everytime you start the bikes?

[@SeanFillner]

Just out of the box and the first time. After that start the bike as normal.

[@lawrence5017]

Hi, Do you think the DNA airbox cover mod is worth the money ? Thanks

[@SeanFillner]

Adds a nice sound...yes

[@nikoschorianopoulos2737]

I own a duke 390 2022 model and it has the same header. I wanted to make a titanium header with the stock chamber and akrapovic slip on . Will that be too loud? I want just a little bit more noise not that much . Also with the fuel x lite or pro will be ok the build ? Or do I need to put it on a dyno . Thank you so much 😃

[@SeanFillner]

Fuel x lite autotunes for any mods you make. "Loud" is a personal preference. What is loud to some may be quiet to others and vice versa.... Thanks for tuning in!

[@masummax1]

Nice video , that will be helpful. What will be the best option to buy fuel x lite or fuel x pro. I am from India , I have KTM 250 Adventure. I don't want to upgrade air filter or exhaust. only fuel x.

[@SeanFillner]

Lite as it autotunes for future upgrades

[@masummax1]

@@SeanFillner Thank you .

[@Quatra05]

Hi, what turn signals do you use?

[@SeanFillner]

Hi Zach! Check out the playlist for this build series. You will find them in the thumbnails....Thanks for tuning in...

[@JJPsyc]

Does the FuelX Lite work well with the K&N filter, DNA Open Airbox and more open exhaust? Thanks!

[@SeanFillner]

It works with any mod you can put on your bike. It's the only one that autotunes for afr changes.

[@waynelonge3049]

Are you going to do any suspension upgrades?

[@SeanFillner]

I seriously doubt it. All 3 of my bikes have suspension that works perfectly for what I am doing. I doubt there is anything I could do that would be considered an "upgrade".

[@Climber510c]

What front fork stand are you using?

[@SeanFillner]

I covered it in depth in my svartpilen build series playlist on this channel. Links are in the description of that video. Thanks for tuning in.

[@SOYLUISO]

hi, great video, how does the the fuel x lite changes the bike? it gives you more power or something? any tradeoff? thanks!

[@SeanFillner]

Changes the afr target.

[@SBMotoZ]

did you have to modify/grind down just the left side, one spot, on stock crash bars ?

[@SeanFillner]

What did the video show/say? I can't help you if you skip through the video or end it early.

[@trailrider1980]

How much ground clearance did you lose with the skidplate?

[@SeanFillner]

I gained clearance because I removed the oem exhaust/skidplate setup.

[@arcadegamesify]

@@SeanFillner The t rex skidplate has more clearance than the stock one??

[@ianparkes2538]

Don’t understand why you would fit a high flow header and leave that heavy restrictive centre box in place , surely deleting that first would make sense and cost less

[@SeanFillner]

I will tell you why: these motors need some sort of backpressure and removing every restriction eliminates that. Also they sound better with a header and the oem chamber. I am not concerned about weight savings on this bike at all. It actually rides much better with some weight on it. Also, cost is not an issue at all for me.

[@ianparkes2538]

Have you tried without the mid box ? Why would this particular motor need extra back pressure from that box , when every other motor gets it from the silencer , not sure if the new front pipe has a cat or not ?

[@SeanFillner]

@@ianparkes2538 I own 3 bikes with the same motor. I covered this in depth in the build series playlist for each bike. You may want to do some research as it seems like you are not knowledgeable on this particular motor or subject.

[@ianparkes4452]

@@SeanFillner yes trying to do some research into this bike can you post a link to the vid where you do this exhaust comparison . There’s a ton of vids and I can’t find the one
