Hi all, I have just picked up a 2015 KTM RC 390. It starts and runs well. It will die if you leave it idling for a few minutes but that doesn't bother me too much. Problem is when I gradually accelerate it get stuck at around 5000rpm and struggles to pull. It eventually gets past the blip and...
Hi guys!

I did velve adjustment, 3 velves ware off, nothing big but still, chain tensioner looks like its doing it's job, everything is seal, fresh oil, factory...
I am selling a brand new Power Commander as well as DNA filter and MNNTHBX airbox lid. All items are new, never used. The Power Commander comes with the oxygen sensor which is no longer available.
Power Commander is for a 2015 KTM RC 390.
Items all together go for 553 before tax and shipping...
I ask because the stock filter appears large enough to flow more than enough power for our engines. I've seen similar sized filters for car engines. Even a little Kia engine is going to make at least double what ours can make even fully modded.
Anyone have good back to back dyno evidence of...
DynoJet PCV and QS sensor for 15/16 RC
Looking to sell the kit to someone building up a winter race project... I converted the race bike to street trim and no longer have a need for them. PCV comes with map from Chad for production class (snorkel, exhaust, air filter). Looking for $400 for the...
I picked up a 2016. The previous owner had an Akra full exhaust (no cat), a K&N filter and PCV installed by a dealer in North Carolina. I assume they installed the Akra flash when they installed the exhaust. I am experiencing a lot of popping on decel and suspect the map on the PCV is not...
Bought a used rc390 with an unknown history. All signs point to a gentle life before my ownership but it's not known if the previous owner maintained it.
So far I have changed the oil and replaced the filter & screens, flushed and replaced the coolant, cleaned/lubed and adjusted the chain...
Hi all, recently purchased a 2016 RC390. Its my first bike and I love it. I have been lurking since I purchased it and have been trying to pick up information.
It was used with an unknown history but appeared to be in decent shape. Took it home and replaced all the oil & filter with Motul...
Ive been trying to find a definitive answer as to weather or not there are any downsides to flashing the ECU with simply a stock pipe and K&N drop in filter. No other modifications of any kind. If anyone knows I would appreciate the info. Thanks.
Random bits of info (or how not to make the same mistakes I did)
This is just random bits of info I learned when I did this stuff:
New radiator
PowerTRONIC ECU
JRi shock
Emissions removal
Some other miscellaneous crap
The airbox cover has two tabs towards the back that slip into slots on...
This bike came to us with a mild super sport setup and we made a few gains! This bike is a high comp, closed airbox, K&N filter, Yosh pipes, Ti retainers, PCV, with a fair bit of Gray Area special sauce. This bike is on track and absolutely destroying it!

Hey guys,
I'm wondering if the 2017 RC390 air filter differs from the 2016 one?
I'm looking for the K&N oem replacement one, but seems there's no one specifically for the 2017 one?
Thanks in advance for your help!
Hi so I succumbed to temptation and put a BMC air filter in and popped a slip on Ixil muffler on my 2017 RC.
It goes like the clappers but I now notice an increase in vibes through the bars at around 70km/he that wasn't there before.
It actually doesn't feel that good compared to how smooth...

Good day,
Has anyone experienced this? I did myself the first oil change for my bike but I over-tighten one of the two bolts for the engine oil filter cover. Brought my bike already to the nearby machine shops but no one dares to give it a try to remove the broken part due to its small...
