- Hello everyone! In this video I install a K&N air filter, a nice new exhaust, and I load an off-the-shelf tune to the Power Commander for my setup that ups the redline from 10,500rpm to 11,500rpm and boasts a gain of 13hp (above the stock 44hp) with the mods I have. 44+13= ...well, pretty close to 60! ;-) Let me know what you all think down in the comments! I'm also working on a review video where I'll do more riding and talk about how the bike feels and sounds with these new mods, I just ran into a small snag... so it may be a couple of weeks before I can finish it. Thanks for stopping by, everyone. Ride safe and have fun! (and stay cool! :-#)

***UPDATE: Since installing everything, I have run into a bit of a heat issue. The engine coolant temps seem to be maxing out when riding in the city or in stop-and-go traffic. It only seems to cool down at freeway speeds. I'm working on a couple of fixes, so I will have subsequent videos on those fixes soon. If you are thinking of doing these modifications to your bike, you may want to check those videos out first.

Nice job brotha RC 390 are really nice looking bikes also stay safe brotha enjoy.
Thank you brotherman! 😁
1st time seeing one of your vids. It was great! Looking to get a 2015 390 soon. Killer sound as well!
Thanks bro! Heck yeah man, I hope you get it!
180km/h 10200rpm with or without a tune. With raised speed limiter, the speed on display will show 202km/h at 11500rpm. 😊and then you need more power.
Oh nice! Thank you!
Man this thing will never see 60 with just those mods.
60? Hahaha are you kidding? Or you are just delusional
If I were to buy an aftermarket ECU that I can tune, is that safe to do if you haven't altered anything in your engine like putting a race gasket on or putting stronger racier piston piston rings, coils Etc. Stock internals can handle the higher ram's okay.?
Yes! They usually come with a minor off the shelf tune that just squeezes a little extra power out of the engine: even completely stock. They also open the bike up to things like quick shifters and power modes.
Hello, does keeping the airbox open give a noticeable difference? Because some people saying opening it decreases the air compression into the engine because excess air escapes... I'm new to this modification so I don't know what to do... Would appreciate the help.
Since opening the air box was the very first modification I made to the bike, I did not notice any performance change other than the sound. If you still use a filter and the correct bracket to hold the filter in place, there shouldn't be any air leaks or decrease in performance. In my research, I found that the length of the stock tube leading from the throttle body up to the air box itself was specifically designed to increase torque and that you should not replace it with a cone filter unless you don't mind losing some torque. Once you get an aftermarket exhaust (and a proper tune) then you should notice more of an increase in power having thr air box open than you would with the airbox still closed. Just make sure when you open the air box that you either cut the top off of the air box lid and still use the stock air box lid (like I did), or else get an aftermarket bracket that will still hold the filter in place and make a seal.
I think the linking pipe is for the generation 1 duke/rc
Yeah, that's probably what it was. And the 3rd-party seller on Amazon didn't specify that. Ugh...
@@FaerodynMoto Leo Vince ftw!
Did you ever get the bike on a dyno? I have the competition werks high mount exhaust with the cat delete on mine. I want to do the k&n filter and a power commander next. Nice video!
Thank you Andrew! I haven't had the chance to do that yet, but I really want to dyno the bike. I'm jelly: your exhaust sounds bad@$$! I have a video on how to install a PCV if you get one!
@@FaerodynMoto have you done it as yet?
Hey there! I did the full werkes exhaust too with the K&N air filter but noticed it’s too loud for my taste, did you do anything to get the noise to quiet down? I ordered the baffle from werkes but wanted to ask in case there’s something else I could do
@@RC-br1ps not yet. :-)
@@juanaliruiz990 yes: I have a dB killer (silencer) installed in the muffler to keep the noise down, but when I go on long open road trips I remove it for full sound!
I wonfery how much u can get the power increase if u replace the airbox inlet, it might just add some more power to your tune
I did some research into replacing the stock air box with a simple cone filter to increase airflow into the engine. What I read is that the length of the stock intake stack leading up to the box was specifically designed to increase low-end engine torque. If it is replaced with a cone filter, the engine will gain a little more top end power but sacrifice the low end torque off the line. It was recommended not to do this, since the low end torque is where the 390 engine excels.
How much power did you get out of it? It's been 2 years now so hopefully it got dynoed.. What's the top speed?
Sadly I have been so busy with work and school I haven't had much time to do anything I've wanted to. My schedule has opened up a bit recently and I was able to find a shop near me that has a Dyno for motorcycles, so I plan to take it in and get those questions answered once and for all!
I need the kink for the midpipe haha
Shoot, I can't remember where I bought it from. I'll have to do some research and see if I can find the exact part and a link for you.
How did you get to the 13hp increase? Honestly I don't think that's the case..... Take it to a dyno and find out....
It's all in the tune, my dude!
Yeah, I'm kinda curious too. The butt-dyno says it hauls @$$ now, but we all know that real dyno's are much more accurate. :-)
On a more serious note: this wasn't a tune I found on a free chat forum. I actually purchased it from a reputable team that specializes in KTM's, so I feel confident that their claims weren't fallacious. Or, at least, not THAT fallacious. Haha but time will tell!
@@FaerodynMoto thanks for replying... I understand the tune.. but there are physical limits you can't bypass.. especially on a single cylinder... with the tune you're able to play around with timing and fuel... but can't make miracles... if you ask me, probably you can increase 5-6 horse power... to a max of 48-50hp.... but nothing beyond that... but it would be good if you can test your bike on a dyno and find out about the real number... of course you need to do a base run with no mods first under the exact same conditions to make it fair... if it does make 13hp more, please send me the link, I'll buy the tune immediately!!! PS: I love RC390s and own one :)
@@LuisJimenez-ue7mr You got it, brotherman!
1 more thing... once you take it to the dyno, you will realize that past 8000rpm there's no more power or torque... so is just over revving the engine till 11.500rpm.... I would stick to 10.000 rpms, specially knowing how "delicate" these engines are...
@@LuisJimenez-ue7mr oh, good to know. Thank you!
I want to see dyno results please.
Me too! Hopefully soon...
How much power is it making
I'm not sure. I've been so busy I haven't had a chance to take it to get dynoed
Any links for the midpipe?
I can't remember the exact part name. I'll try and see if I can find it.
forget the engine. Swap out the front and rear suspension for some quality parts. you're never gonna make this thing faster but you can make it handle so good that nothing comes close in the twisties.
That's not a bad idea! Do you have any recommendations?
In the rear I have an old shock from a yamaha r6. they fit and are pretty cheap. In the front you should think about swapping the fork internals for cartridges. Andreani offers them but they're pretty expensive. @@FaerodynMoto
🤔 Yamaha R6 rear on a KTM 390? Nice! I would have never thought. Does it change the seat height?
What exhaust is that?
Leo Vince
Bro to push the claimed amount of power, you need to have different internals (basically a built engine) no way stock internals push that hard cuz you would damage the piston heads instantly. Also your headers are stock with the cat on so, its basically not 60hp shd be in the ballpark of 45-47hp at the wheel (50hp at crank).
🤔 Hmmm... Makes sense, you could run into those kinds of problems on a car or truck if you heavily modify the power output on stock internals... Still, seems kind of weak for a bike that boasts "Ready To Race". I'd love to see what it's actually making, I just need to look into a motorcycle shop near me that has a Dyno to test it out.
Something tells me ur not the brightest
Stage 1 map from mantra racing puts out roughly 52bhp think the stage 2 puts out 55bhp check them out MANTRA RACING
Bend a coat hanger into a spring puller.
I didn't think of that. 🤔
Thanks!
which ecu are you using?
I'm using the Power Commander V.
DynoJet Power Commander V
@@FaerodynMoto ok thnx
Ah, the old china knock-off akrapovic
Haha heck yeah! $35US on Amazon vs $310US... It's a no brainer for me...
@FaerodynMoto except it's cheap trash not even close to the real thing
@@Zehnuss Meh. It's a muffler. Its sole purpose is to quiet the bike, and it does exactly that.
Upping the redline sounds like a terrible idea.
It increases the bike's top speed, but you have to be careful not to raise it too much or else you start excessively wearing down engine components. 😬
imagine buying motorcycle part on amazon, always a mistake
Amazon often has poor quality parts from China, but there are times in all of our lives where we must choose between quality or affordability based on our $$ budget. To buy the crappy part, or to not buy it at all. 🤷♂️
@@FaerodynMoto or just wait and save money and buy the quality part. I'll never understand that fucking argument... You don't have the money now? Wait and you'll have it at some point. I ain't rich myself but i'll never buy cheap shit
@@KittanBachika everyone has the freedom to make their own choices in life. :-)
Click bait, BS.
373 cc 60hp, not how your doing it.
*Spits Monster on keyboard* Lol you mad bro? 😂
Dude 75hp 690 makes 210km.
potential max hp for duke or rc 390 is 48 hp.rest is fooling yourself
Bike sounds like it wants to die
Oh really? How so?
I don't know what to listen for...
@@FaerodynMoto ignore the dork hes just a knucklehead hating on beginners,sounds perfect brotha love the bike
@@CcTrippy Lol thanks bro! I thought maybe the bike was misfiring or not properly tuned and I just couldn't tell. XD
Ignore the haters
