Re: KTM Duke 390 - Owners Reviews and Experiences

If the fan is switching on then it means that the engine had increased beyond normal operational temperature. ie. beyond 96 C in coolant. It is well known that the head transfers heat to the coolant, which is kept in circulation through a Heat exchanger for reducing the engine temperature. The Internal temperature of engine on combustion will be anywhere between 600 to 700 degrees, and this heat is quenched through coolant and engine oil...With static coolant and head heat at greater than 96C , the seals will start to fail after repeated exposure to this kind of transients. There is grave possibility of engine Gasket Failure leading to Coolant and Engine Oil mixing to-gether.

Whether the fan spins Clockwise or Anti clockwise, as long as it is in free air, it will push relatively cold air through the Radiator....My point is , with a guard in front of radiator like a window Louvers, in-rush of cold air in any direction will be difficult and cooling will be in-efficient, compared to open radiator .
Since I don't own a 390 I can only guess, and would request owners to take my observations as that of a child trying to learn .

@Legend Racer.. Something like what you have experienced happened to one of my friends KTM 200. The bike would switch off randomly at first, but would start..then after 3 or 4 times ,it stopped dead in traffic and would not start. The bike was safely parked in a friend's place.The bike had done only 1,400 Kms ,and since it happened on a Saturday the ASC promised to look into it only on Monday..So I went to see the problem..All connectors ,and Fuses were firmly in place . I operated the clutch lever few times and tried starting with no response...then with clutch lever pulled in and throttle wide open I thumbed the starter..the engine coughed into life, and I immediately let go of the throttle and clutch lever...the next try the bike started normally as if it was ok all the time...The ASC took the bike later and told the customer that there were no error codes, but to be on safe side they Re-Programmed the ECU...so far the bike is running ok...

Ah, now it makes sense. Thanks Psr!

Re: KTM Duke 390 - Owners Reviews and Experiences

@psr

i suggested ECU reprogram. they had a laugh at that. i felt like crushing him. now i can only wait. SM also said compression problem is shown only while starting. i dont understand how. if it's matter with compression, it should be there always ..isnt?

Re: KTM Duke 390 - Owners Reviews and Experiences

please dont leave your bike with those ass-es.you know that they are inexperienced and clearly egoistic fools.you don't have to go through what i am suffering now thanks to ktm vytilla.dont let them touch the engine!get in touch with dukedey and if at all possible get it fixed at tvm.since the guys there are oldest wrt handling ktm in kerala i believe.

Re: KTM Duke 390 - Owners Reviews and Experiences

thats the reason i went to tvm. as the saying, a known devil is better. [MENTION=63586]DukeDey[/MENTION] would be busy or else i got to go on 26th and sit with them. today they didnt do any work.

Re: KTM Duke 390 - Owners Reviews and Experiences

A little busy with work these days. Would call tomorrow and discuss.

Even I need to take my bike to the svc on a Saturday so that I can stay with the bike when they fix the tappet noise issue. They are saying one full day is required as its precision work. I want to see what exactly they plan to do. I want to look after the work that is why will visit on a holiday, Jan first Saturday I'll take my bike.

Re: KTM Duke 390 - Owners Reviews and Experiences

k.click pics of the work/service progress whenever you can.u have done this before i believe.before and after pics.u will need it in the extreme case they screw up your bike as evidence.rite now i dont want any other owner to go through what im facing.also keep tabs on the distance and fuel.the ass ripped me off on this.
o.t. what's your riding gear comprised of? helmet is sf2.waiting for a review.

Re: KTM Duke 390 - Owners Reviews and Experiences

Yes , and your problem is not related to compression...I am sorry to see that the ASC is so stupid and Idiotic....absolutely no common sense...It is not isolated to your place but wide spread..But we try to bring pressure by asking them if they have the ECU reader/programmer ,and what is the course of action ,and why etc., basically making them understand that we are not noobs and do know about technical stuff....
Ask them not to open engine or tamper with any internals...if they do, then collect all data in writing from ASC on work done,and write a letter to KTM and ask for new engine since they had supplied a defective one which needed opening so soon in warranty period.

Re: KTM Duke 390 - Owners Reviews and Experiences


if they are not supposed to open it, when under warranty, what about @DukeDey case? to rectify tappet noise it needs opening up, isnt? or is it that, if under warranty the engine needs opening up, we must fight and get a new engine? kindly explain the rules and procedures...
my understanding is that no matter what, once delivered, SVC is the one who should ask for engine replacement if they cant rectify it. if they fail, then we must move to ktm or to consumer court.
their knowledge is pathetic. got no words to say...

BTW there was no error code. some of my problems are, occasional stalling, long start up time. starting trouble after tank full.

Re: KTM Duke 390 - Owners Reviews and Experiences

[MENTION=31923]Legend[/MENTION]racer...You are right in saying that to adjust rocker gap and replace shims they have to open the engine...but it is the top part, and they will be opening the head cover only. For compression problem if they open the head, it is the Bore and Head they are referring to, which should not be done without Senior Service personnel from KTM factory being present..
You are right in saying that it is the ASC who can recommend for a engine replacement. I was requesting you to escalate the problem with ASC on this subject.. Sorry to see your problem and the useless ASC.

Re: KTM Duke 390 - Owners Reviews and Experiences

Sir,
What kind of noise are you getting, is it like a sewing machine noise? If yes, the tappets just need adjustment and it merely takes 15 minutes. Me too interested in what precision work they are talking about. Please keep us updated sir.

Re: KTM Duke 390 - Owners Reviews and Experiences


has anyone tried this one Performance Racing Store. MOTUL - P3 Tyre Repair
p.s i have no idea how it works, was going through that site and saw it.

Re: KTM Duke 390 - Owners Reviews and Experiences

Got my Duke's first service done last week.

1.) The front disk noise is fixed now. Brake pads were replaced under warranty. Rolling stoppies are no longer noisy.

2.) Chain slack was adjusted. The mech told me it needs to be adjusted every 1000kms as available chain play is very low! I was thinking about taking this bike out for long rides. I can no longer think about this as I dont like adjusting chain every now and then.

Overall, not as good ownership experience as 1st 1000kms of Ninja. Even though I use this bike much less!

But each time I take the Duke out for a ride, I forget all these problems. It keeps up with my friends 600cc super sport bikes and I dont need to fill Speed 97 either .

Re: KTM Duke 390 - Owners Reviews and Experiences

After my first service at btm, the engile oil color seems greenish. But the coolant level seems ok after neary 700 kms of riding. Should I be worried about the engine oil color? It is just that I have to ride another 700 kms to reach Blr

Re: KTM Duke 390 - Owners Reviews and Experiences

better get it checked. thou coolant mix in my case brought up the fluorescent green colour.normally oil should look dark red anyhow.
