Hi how did you manage about the heat? Did you make it rich or install spal fan or install dual fan? I got tune and think afr is good, but stil full temp on city and fan always working actively
@greenblue980 I swapped out the engine coolant for Engine Ice, installed the SPAL fan, and got an off-the-shelf tune from Rottweiler Performance and loaded it onto the Power Commander V. That seems to have fixed the issue, but you can also upgrade the thermostat, radiator, and the hoses if it is still having a heat problem.
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.
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
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.
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 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.
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.
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@$$! I have a video on how to install a PCV if you get one!
Hey there! I did the full werkes exhaust too with the K&N air filter but noticed it’s too loud for my taste, did you do anything to get the noise to quiet down? I ordered the baffle from werkes but wanted to ask in case there’s something else I could do
@@juanaliruiz990 yes: I have a dB killer (silencer) installed in the muffler to keep the noise down, but when I go on long open road trips I remove it for full sound!
Bro to push the claimed amount of power, you need to have different internals (basically a built engine) no way stock internals push that hard cuz you would damage the piston heads instantly. Also your headers are stock with the cat on so, its basically not 60hp shd be in the ballpark of 45-47hp at the wheel (50hp at crank).
🤔 Hmmm... Makes sense, you could run into those kinds of problems on a car or truck if you heavily modify the power output on stock internals... Still, seems kind of weak for a bike that boasts "Ready To Race". I'd love to see what it's actually making, I just need to look into a motorcycle shop near me that has a Dyno to test it out.
Yea my 2019 RC390 has all the bolt ons and it's not touching 50hp. PCV, custom airbox, large injector, k&n with open lid, full exhaust, dyno tune and it's making 44.5hp to the rear wheel. You'd need to get the high comp gasket kit, upgraded valves, titanium valve spring retainers and a DCR camshaft to start talking 50hp. At that point, may as well add in the gray area fire ring cylinder and upgrade the piston and connecting rod. May as well buy a faster bike lol
It's all in the tune, my dude! Yeah, I'm kinda curious too. The butt-dyno says it hauls @$$ 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 :)
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...
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

Nice job brotha RC 390 are really nice looking bikes also stay safe brotha enjoy.
Thank you brotherman! 😁
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!

@@VinRence I use what the owner's manual says to use: 1.7l (1.8q) of SAE 15w/50 Fully Synthetic. The brand I got was Mobile.

@@Zehnuss Meh. It's a muffler. Its sole purpose is to quiet the bike, and it does exactly that.

How much power is it making

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. 😬
