Could be an electrical or sensor glitch.
Tell them to re-calibrate the ECU once and then re-check everything.
Eat the ASC's head out on the issue-you will definitely get a solution.
A fellow owner had a stalling problem just because his side stand sensor had gone bad due to a loose side stand stay-get this checked too.

I'd suggest you to check your fuel lines and the fuel pump itself and see if the pressure is on the right side, 42 psi IIRC. When was the last time you replaced your fuel filter? Is this stalling happens only when you pull in the clutch while cruising? If yes, check your sidestand sensor, as they have been notorious to cause the clutch pull induced stalling when coasting to halt or shifting. Clean the area thoroughly, if possible replace the sensor switch and see how it fares.

The bike stalls only on cold starts when I close the throttle in downshifts. When its already been running for a while, it doesn't stall when I downshift and close the throttle. I have one place left to get this fixed (KTM Pallavaram suggested by Imam). If he can't fix, I have no other way but to sell this off.

Well, different people have faced different issues, some side stand sensor, some ABS sensor, etc. Probably they'd have hooked your bike to the DIAG TOOL and come to the conclusion that your ROLL OVER sensor is kaput. Get it replaced. It isn't a deal breaker per se, but seeing a warning all the time isn't what a rider wants. It's just that a sensor can go kaput at any point due to n number of reasons, plus these aren't really expensive sensors, so fret not.

Got it replaced yesterday and costed INR 243/- . Now I can ride the bike with a peace of mind

Also I need to replace my rear tyre and the current stock metz would come for around 1-2k kms max. I was thinking of Michelin PSR but I am confused with the size because few have gone for 140/60 and few have got 150/60 fitted. I heard that the 150 section tyres will brush the swing arm . Please help!

Thanks

150/60-17 is THE stock size-so no worries.

As far as I know, only Timson 150/60 touches the swingarm.
Rest all tyres are good to go.

Update on the stalling issue: ASC said Throttle body was the culprit and needs to be changed, but it is stalling even after changing the TB assembly. It seems ASC is unable to figure out the problem. If I can't find and fix the issue, I might have to sell it off

did they replace only the tb and put back the existing tps and idle control stepper motor ? The TB usually doesn't go bad.. it's either the tps or the idle control stepper motor.
Now, try to swap the tps, idle control stepper motor (both these are mounted on the TB) from another bike and check. Also would be a good idea to swap the O2 sensor as well from another bike.
Sometimes cold starting issues (though you say it's idling issues) maybe due to incorrect valve clearances . Might as well get them checked too.

Re: KTM Duke 390 - Ownership Reviews and Experiences

Hello guys,
In have a 2014 Duke 390 which has run around 14000 kilometres..
And I have this weird clanking type sound from inside the engine, which is due to camshaft and rocker arm on one side getting eroded, got it checked and the guy replaced them, but the sound comes back after riding for around 100-200KM's.
It's the fourth time I am getting the sound and have replaced them 3 times, it costs around 4000 every time.

The mechanic at the ASC always says that he has checked everything and the problem is only in the camshaft and rocker arm and replaces those.

Any other part to be replaced?
Or
Any other thing to be done?
Has this happened to anyone else??

I would suggest you check your crank shaft bearings too. A failed or a "failing in the process" bearing too can make weird clatter and sounds inside the engine. Secondly, cam lobes having scores or "eroded" in your case means, poor lubrication to the cam followers and camshafts. If the oil galleys to the head is blocked you will have oil starvation to the valve train and these issues can pop frequently.

Hi Guys,

Anybody using NGK sparkplug?
How is it?
Thinking to buy one.

Re: KTM Duke 390 - Ownership Reviews and Experiences

My stalling issue is now fixed completely. It seems there were two reasons for the stalling, one the throttle body and two very low clutch play. After I adjusted the clutch and set a good enough play, it is no longer stalling now.

Entire tb assembly was changed. idling is now a lot more stable than before.

That's great news, Ezil. If you could go back a few pages, to another member, I've mentioned the same note about clutch play adjustment is vital and echoing the same comment here. Usually, the bikes have zero clutch play right from the showroom. Right clutch play is very critical in improving clutch life as well as rideability, especially when it comes to low speed riding and choc a bloc situations. Do observe your bike for a few more kays, and do post your observations if the issue has solved completely.

Hello friends,

I am looking forward to bring back my passion of biking again. I had R15 v2 as my last bike which I sold later on. I am using i20 from last 2years.
Now I want to re start biking because of 2 reasons 1st is distance b/w my home & office is 40kms which is not manageable in this traffic with car & 2nd is my passion of bikes.

My heart purely say to go head with duke 390 but brain says dominor make sense.

I heard there is lot of issues with 2017 duke 390. Has KTM fixed all the issues they had with this model?

Request you guys to throw some lights & suggest me what makes things much strong case to go head with duke on dominor.
