Cam Chain tensioner i Had replaced since it was making a squeak (like Automotive Auxilary belt slipping) that occurs on an inclined road when the engine is warmed up. So replaced it with a new part (probably a 2022 KTM 390 Duke part I dont have the part No with me) with new cam chain tensioner...

Following the semi-successful parting out of most of the aftermarket parts on my 390, I'd like to throw out a feeler for the rest of the bike. It is just too time consuming for me to part out the bike to the frame. So, I'm listing the rest of the bike to be sold, as-is, to someone who needs or...

My 2017 RC390 has engine light on and it's not going off. The OBD2 tool shows the following three codes P0500, P0112, and P1201. I am wondering if my motorcycle has any serious problem and needs to be repaired. I cannot find KTM error codes list that describes these codes; I am especially...

Messing around with my 2016 RC this morning I found out I need to replace my clutch cable. It was about to break at the lever. Now, I did remove the cable and thought I would try moving the clutch lever on the engine and put it in gear to see what would happen and it kills it every time I put it...

Hey! Couldn't find a thread with my issue, as its slightly different from all the other "engine cuts out" threads. I recently blew my head gasket at a track day, so pulled my motor to change it and do my valve clearances all in one go. I had some issues getting the oil scraper ring back in the...

Hello everyone. Just joined the group today. I'm looking for a replacement engine on my 390. Any suggestions out there? also looking for recommendations on service/ repair shops. Thanks!

Working on my 17' RC390 and there is rubber sheeting zip tied all over. Is this important? Does it keep wires off the hot engine? Is it cooling engineering? Have you all removed it with no effect? Any info appreciated!

Hi does anyone know how to get the rc 390 2017 stock header off it get stuck between the engine and frame when I try to remove it surely I don’t have to remove the engine ?

Crunchy is the best way to describe the feedback from the clutch lever... There are a couple of rough spots when pulling in the clutch. This issue is only when the engine is on, it doesn't occur with it off. The clutch pull feels incredibly smooth with the engine off (the clutch isn't spinning...

After leaving the bike on a trickle charger over the winter, I decided to take the bike out around the block since the weather is much better. For some reason, the Yellow Engine light seems to stay on no matter what. It's been like this for almost a week a now. I rode the bike for 15-20 minutes...

2018 RC390 is having some stalling issues in two circumstances. I understand this to be a common problem, but there are no resolutions (apart from one I've listed below) OR people just forget to reply with their resolution. Brand new bike, less than 100 miles. Two separate issues: 1...

So I recently bought a 2018 RC 390, and while I couldn't be happier, I have been experiencing persistent stalling issues. They would usually happen at low speeds, particularly on the 1st or 2nd gear. I would have the clutch disengaged, and the engine would just turn off as I am trying to blip or...

I connected a OBD2 scan tool to my 2017 RC390 and got a code P0335. After doing some research, the code is related to the crankshaft position sensor / ignition pulse generator. The engine check light was on for a while but gone after a ride, bike seems to run fine. Has anyone have experienced...

My check engine light is on after the fuel pump and ignition fuse was tripped. The fuse is replaced and everything is running fine but the engine light is still on. How can I reset the computer to make the fault clear and turn off the engine light.

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?
