engine

My RC 390 only shows correct engine oil after a ride, so I ended up with 1.8l of engine oil and now it's showing higher level after a ride. I was wondering if there is a way to drain extra engine oil without opening the drain bolts and how bad is to have 100ml extra oil on RC 390?

The more I dig up on the 17/18 390 engines the less I think I want another one. WP seals, coolant swelling paper oil filters and catastrophic engine failures? Might be tied to the head gaskets too? Geez. So, before I give up, are there any SS screen style oil filters for this engine? I...

Hey guys . After a little research i found out that if you short the 2nd and 3rd slot in the Alarm connector (in the top row), both the indicators will blink at the same time .But this only works when the Engine is off , when the bike is "running" the indicators are blinking inconsistently. Is...

Has anyone experienced this? At the last couple of race days when Ive changed down an extra gear to normal and hit the limiter, twice the engine has completely died. Once I turn the ignition off, then back on it starts again. I have been told that if you hit the rev limiter for longer than 3...

I have about 600 miles on my 2017 RC 390. A couple of days ago the engine shut off in traffic in second gear with clutch pulled in, the bike started back when I release the clutch. Today, I just started the bike to warm and it shut off after a minute of idling. I was wondering if this is normal...

I have a 2017 KTM RC 390 and had ridden it about 500 miles; just realized that the oil is on the lower side (picture attached). I ran the engine for a while, waited for a minute, and the bike was on rear stand. I was wondering if running on this much oil would have caused any damage. Would it...

I landed an opportunity to pick up a 2017 390 engine as a spare to my 2015 race bike. Was just curious if I should be picking up the harness/ecu as well or not? Meaning, are there any differences/challenges that I'll face jumping between the 2017 and the 2015 when the time comes? Thanks in...

Has anyone fitted a 16 tooth engine sprocket on your 390? KTM do not sell them so what brand did you use? Parillaguy

Hey Guys, Facing an issue on my week old 2017 RC 390. After about 200 kms on the odo the bike suddenly started feeling very rough below 4000 rpm. Initially was very smooth (relatively speaking) but all of sudden became very rough. A lot of vibes and jerkiness from the engine. Feels better post...

Ok, so dropped a valve ordered a new engine, and got it in. Problem is the shop I had taken it to initially never re connected almost anything so I've had to figure it out on my own after I changed the motor. I have two coolant lines coming from the front overflow bottle. One is a drain/vent...

I would like to attach a tachometer to the RC390 model of the 2015 model, but what kind of color wire should be connected on which side to receive the engine rotation signal? Also, where is the wire?

Hello. Because the tachometer and the shift indicator of the genuine meter were small and the visibility was bad, I wanted to install the shift light LIGHTRONIC LT 200, but in order to install it I have to pick up the engine rotation signal. Is there a person who knows where to get the engine...

Anyone tear down their engine and look through it and make sure everything fits properly? I'm trying to formulate a list of things to do this winter (I'm a planner, what can I say) to upgrade my bike and put it on solid footing. Thinking a nice engine out service would be a fun learning...

Hi guys, So, background: 2015 rc390, new to me at 12k kms (Canadian) last winter. Then proceeded to build it into a race/track bike with the following: - PCV (chad map) - akra flash - shift kit - custom exhaust - all the other usual stuff not relevant for this discussion (see pic) Last...

Hi, I'm having difficulty in engaging gear during WOT . I'm not able to upshift when my rpm is above 9k. Anyone experienced this issue before? I thought it might be the engine oil (Motorex about 2k km) and i just changed it to Motul 300V 15W50 but the problem is still there. Thanks.

Just done an oil filter change and found out engine casing bolts are made of cheese! Has anyone fitted or got any gen on the Pro-Bolt kits? Wondering whether it's worth shelling out some Pounds, Shillings and Pence on a kit. Any idea what's best Steel, Aluminium or Titanium! Thanks *Side...

This is my engine level after first servicing oil change. it barely hitting minimum level is it normal guys? or i they didn't change oil? I have attached image please help me out.

Bike was having a helluva time staying cool and my last track day i thought i made had the head gasket issue. Got my bike down to chad on my way to Georgia and Alabama. He had the engine out and basically figured out the issues while i was still on the road! Stayed in touch with me the whole...
