    Oil disapearing

    Hey, I got a 390 Duke with a major issue. The bike runs perfectly well for 30min (no loss of power), but after about that time the "low oil pressure" sensor lights up and i have to stop the bike. At first i thought it was a deficient sensor, but after checking the oil level (on a cold motor)...

    Making Andreani's Work

    I’m not a suspension expert by any means, nor do I have a degree in fluid dynamics. But I’ve been involved in motorcycles for a while, I’ve done forks swaps, had forks revalved, etc. I’m not writing this to provoke responses, but trying to pay it forward. I wished I’d had access to this...

    Engine cutting out after being rebuilt

    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...

    Inside a blown-up RC390 engine......it happened to me

    So some of you might remember me- I joined this place a long time ago. I was told by my dealer I was the first person in the state of GA to take possession of an RC390, MY2015. I left this forum and said "see ya!" a year and half back when the motor decided to lock up in the N. Ga mountains...

I searched long and hard before finally settling on my bike, as it was truly the only thing in this category that interested me. This thread is meant to document the story of my bike and the...

    2015 ~5k Oil Weep

    I picked up a 2015 with 5k on the clock a month ago, and am now tackling the oil weep that it's had since I got it. The drip collects on the left side of the bike, right where the left hand rear stay for the belly pan is. Its about 3 drops after every ride on the tarmac. No oil is coming down...

    Low oil pressure warning

    New rider and I’m out of my element when it comes to bike issues. I recently did my first service on my 2015 RC 390, I used 1.75l of oil and changed the filter. Ever since my first service my low oil pressure light keeps coming on but only when the bike is up to temperature. I didn’t have this...

    2018 RC390 -- white smoke?

    Hi all, I've researched this issue a little bit and found it to be pretty prominent, but not much clarity or resolution. There is white(ish) smoke when starting up cold, or hot. It continues when revving. I'll clarify a few points below: - 400 miles - There's no mixing of coolant and oil (I...

    Level after an oil change

    I have a KTM RC 390 for which I recently got the engine oil changed. They changed the oil filter too and they used 1.5l Motul 7100 4T as recommended. Thing is that I noticed the oil level is not between the mark that should be and I checked it a couple of times. Then I checked with the KTM...

    I put oil in coolant tank

    Ok this is super embarrassing, but I thought I needed to add coolant, because when looking at reservoir, it looked empty. I quickly grabbed a quart I had on the bench, thinking it was coolant, because I remember buying some and I thought that's where I set it. Very dumb, yes I did not even...

    Track Day Oil Changes

    Is it necessary to change engine oil every two or three track days? My bike has Motul 300V fully synthetic oil and I was wondering if it's ok to change it every 4000 miles.

    100cc engine oil overfill

    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?
