Joel, this sounds unfortunate as a new engine behaves in such a way. petrol may be one of the culprit. Confirm if it is 91 Octane that you are using. try shell super if it is available.
Do not run the bike in that condition, it will damage the piston / cylinder. Get in touch with your ASC ASAP.

I will go with your advice and try Shell Super..

But make sure you have a word with SVC people. Just to be on the safe side..

Me too facing similar kind of experience.The Grunt in the engine is not there and the engine exhaust note seems soft(Refined kind of).I doubt whether it is the characteristics of the engine once the engine is run in.I have done 2133 Kms on my bike.

The engine stalling problem still persists on my bike.

Ashutosh.. nice of you to keep your cool.. obvious entertainment as long as it doesn't hurt anyone..

I don't think its right to prohibit someone from sharing their experiences or opinions, just because they don't own the bike. Mountain doesn't own the Duke yet.. however, his plethora of knowledge on the Machines does help us newbies a lot.

Also as devil_rider mentioned, do visit your ASC and get their opinion too.
What fuel have you been using ? Did you run-in the bike as per manual or motoman method ?
Navaroj, what engine oil have you put in at first service ?
As for engine stalling, could you point out as to what makes it happen. Remember duke is a high revving short stroke engine, so there is lots of engine braking, which tends to bring down the rpm quickly when we close the throttle. With practice you will come to know that around 15-20 kmph, engine tends to stall in most gears, so either pull the clutch or change to lower gear and rev it a bit. It stalling is connected to some other issue, ask your ASC.

I agree with this.. Even though a person does not own a Duke, he still can help with his knowledge of bikes just like @Mountain does.

Help from those who have lots of experience is always welcome. But there should be a line between experience & grape wine. There have been lots of instances where someone is reading about an issue in one thread & posting it in another, which keeps replicating in all forums & then some poor soul thinks that this bike is made up of issues only.
Also, this is not a thread to compare bikes.
Everything has a proper place and this thread is meant for this bike!

Hey guys,can you pls comment on the availability of the stock Tires in your city?

Thank you

True bro even I want such buggers to stay away.

My point is that even the non-owners can participate in the discussion.

No offence meant to any1.

the engine breaking subsides after 2 and more oil changes. At least in my case has happened. The exhaust note too changes and takes a bit of refined character than the earlier wild screaming banshee note.This has been confirmed by numerous owners I have met at the svc
However regarding the knocking thing, my bike doesn't knock, but there is this occasional cough/hiccup which I hear when downshifting from 4th and 3rd. I thought this may be due to dirty airfilter or a mapping issue.
Air filter was cleaned and the ECU diagnostic tool was used by the regional technical head to check if my ECU is alright(actually he used it on my bike to teach the functions and how to check various ecu parameters/error codes to a newbie technician, so everything was checked.Lucky me ). Nothing was found faulty.
So don't know what the issue is or if this is a normal behaviour. The problem is the occurrence of the slight hiccup like exhaust sound is not frequent and hence have not been able to demonstrate it to the mechs at the svc.
The lack of pull issue I had reported earlier has miraculously vanished now.I hope I do not have it again.

Right from day 1 i am using shell super only.Engine oil is MOTUL 7100 FS.After this issue the next day i tool it to the ASC.The guys there checked it and said that everything is normal.Below is the list of Check-ups,
1. Combustion chamber pressure - 11.5 Kgf/cm2 (163 PSI).They told that the
normal is between 10~13 Kgf/cm2.
2.In,Ex valve clearance.Inlet - 0.09 mm(spec.0.08 ~0.12mm and Exhaust -
0.18 mm (Spec. 0.17~0.2 mm)
3.Any malfunction in the ECU was checked with the diagnostic tool and
nothing was recorded in it.

Since there was nothing serious in the engine, i was a bit relieved.

This issue started only after engine stalled 2 times consequently (within a span of about 100 metres distance).

Thats why i wanted to know whether the Engine Grunt disappears over a period of time and becomes soft else it is abnormal.

+1, Seems that you too facing the similar behaviour of the bike as mine.

Dear Devil_rider & Doga,

What engine oil are you using ?Just curious to know..

I am using Motul 3100 4T 20W50 technosynthese(which means SS).

How do they check the combustion chamber pressure man?

You sure got me, But I got you too . Nice to see you here.

About the warranty replacement, I'm waiting for the Cochin KTM to open shop this month. Else I will have to do 470Kms to and fro for the claim at the Trivandrum KTM.

Remove the Spark plug,Plug a pressure gauge instead and Crank the engine.If the guage reads a low pressure (Below the spec) it indicates there is loss of pressure due to various reasons.The peak pressure is recorded during the combustion stroke when both Inlet and exhaust valve are in closed condition.Hope it clarifies.

One more thing what rating petrol do u use and what brand?
