Re: KTM 200 Duke

Yea, a new product comes with many unanswered questions.. Since you have booked your D390, hope you get the bike soon and let us hungry souls into what the bike really is in daily life..

Re: KTM 200 Duke

Actually if the injectors are clogged a bit then that would mean slightly less fuel being injected meaning a lean mixture.

Re: KTM 200 Duke

Why don't you try a System G or System 23 dosage with your bike?? It will help cleaning the fuel lines and the injectors as well..

You can also try using Engine Ice coolant to keep your thighs from being baked at bumper traffic. You will have to flush your old engine coolant properly before pouring in the Engine ice Coolant.

Re: KTM 200 Duke


How often does one use this System G for injector cleaning ? Could you explain the procedure too ??

Re: KTM 200 Duke


Usually at an interval of every 5,000 - 10,000 kms, two tankfuls with 2 - 3ml per ltr of petrol for System 23 and 1ml per ltr for System G. Works for carburetted bikes as well. Keeps the fuel line and the injectors free from clogging. System 23 is for 75 - 80 bucks i think and System G is for around 230 - 285 bucks per bottle.

Re: KTM 200 Duke


Just to clear it out, both system 23 and system g must be used for 2 tankfuls ?
So for a 10 liter tank 30ml of system 23 or 10ml of system G to be used 2 times(2 tankfulls)
Am i right ?


Thanks for the cost part too mate..!!

Re: KTM 200 Duke

You can use either of them for the same purpose. yes two tankful treatment is good enough.
[MENTION=48967]Doga[/MENTION]: unless the injectors have been severely clogged, this treatment should loosen up the gum and muck and get burned off soon. you should witness smoother response back. Alternatively, you may also try filling in Speed 97, two tankfuls and see if it resolves the issues you are witnessing.

Re: KTM 200 Duke

Hello fellow Dukers, how many of you test driven the D390, please give me your honest opinions when compared to 200

Also I would like to know how long the front n rear tyre last n its cost, my rear tyre lasted only 6k kms, I think its because of 3-4 burnouts.. Gotta change it ASAP.

Re: KTM 200 Duke

Hey guys! I caught a nasty cold after my trip, so i wasn't able to write anything.

I got a Kiirus ECU remap in Bangalore some days ago, and I tried it in city traffic and also highway.

My MRA RNG windscreen arrived to my friend's address JUST after I left Bangalore day before yesterday, so a write up about it will have to wait till next week when I'm back in Bangalore. Curious to see how it looks on a Duke and how it feels especially in faster highway rides where a wind blast is the biggest problem for Duke...

Just to say straight away that I didn't feel ANY difference in performance between cool Bangalore evenings at 800+ m altitude and at lower altitudes. I think there's nothing to worry about altitudes in either stock or Kiirus ECU maps.

Right after the Kiirus guys changed my ECU with their remapped ECU I tried the bike. I was going slowly in 2nd gear and opened the throttle fully. The bike jumped much stronger than stock one, and kept pulling faster. Woohoo! It's not MUCH more power, but it is noticeable straight away. The lows and mids in any gear are stronger, and the bike pulls and goes faster. 0-100 kmh time should be better, I read somewhere it's 8 sec.

But the interesting thing was that the engine felt much smoother than before. More power but smoother.
It's difficult to describe the difference, but let me try: it fees as if the stock map tells the fuel injector to pump a drop of petrol for example every half second, whereas the Kiirus map tells the fuel injector to pump half a drop of fuel every quarter of second. basically pumping fuel at higher frequency, making the power delivery more smooth. Maybe this is not technically possible, but this is just for the sake of explaining. As if the fuel is being pumped into the engine in much smoother way.

As a result you get a MUCH smoother engine at low rpms. Duke is known it doesn't like low speeds. Well, with Kiirus ECU remap that's no longer the case. You can easily go now on a really bad road at 18 kmh in 2nd gear, and go SMOOTHLY, not with typical Duke jerkiness at low speeds.
If you let the bike go without clutch and without throttle it'll go smoothly at 6 kmh in 1st gear, and 9kmh in 2nd gear.

So, this ECU remap isn't just good for the power lovers, but also highly recommended for those who want to ride their Duke in a more sane and slow way. This was always a problem with Duke.

I have an older Duke with 43T rear sprocket, whereas newer Dukes have 42T rear sprocket. I plan to put 40T sprocket next week, so will do some more tests.

Here's some tops speeds in different gears with Kiirus ECU with 43T / 42T / 40T sprockets: (43T as measured by me, 42 and 40T is calculated.)
2nd gear: 69 / 71 / 74 kmh
3rd gear: 91 / 93 / 98 kmh
4th gear: 115 / 118 / 123 kmh

I can only remember the old top speed in 4th gear, which was 104 kmh. So, one can expect around 10% higher top speed in each gear than with stock ECU.

It looks like the rev limiter kicks in around 11,600 rpm.
The redline at those rpms don't feel too stressed for the engine, just little more than the stock redline. When you rev some bikes to redline you can hear the sound becomes "dirty", it's when the engine has reached its maximum. It's good to know that even at 11,600 rpm this is not the case with Duke's engine. It can go more, but I don't think there's a need to push it more than this. 11,600 rpm feels and sounds what the stock redline should have been.

Highway ride:
Unfortunately, during the highway ride I had crazy head and side winds, which were preventing me from reaching the top speed even in 5th gear.
Some 2 weeks earlier, on the same road and the same time of a day with apparently same intensity of winds, I wasn't able to cross 120 kmh.
This time I was doing 127-130 kmh in both 5th and 6th gears. Mind you, this is with blasts of head and side winds, which affect the speed quite a bit.
The top end power didn't feel different from the stock ECU top end power (with exception of moved rev limiter).
I exchanged few emails with Abhishek from Kiirus and he said that the top end in software map is completely maxed out, can't be stronger.

So, the low and mid revs are quite stronger, much, much smoother, but the top end doesn't feel much stronger than stock (which is anyway quite strong, there's a noticeable surge of power after 7000 rpm). However, the top end now has higher rev limiter, so you can push the top speed 10% higher.

I am not 100% sure, but I think I may have hit the limiter at around 136/137 kmh.
That reminded me that this speed was where my engine was cutting off when I had an old first ECU map. I was confused to read everywhere that the others have the rev limiter at 139 kmh, but mine was cutting out at 136/137 kmh. After some months last December I got a new ECU map from KTM with a 134 kmh (10,000 rpm) limit, so I forgot about it.

So, it could be very likely that my speedo console is limiting the top speed at 137 kmh.
it looks like both Kiirus and Motozone guys were right - it's the speedo that limits the top speed, and this limit is different in different bikes.
I will do more tests, but if I see I'm really limited to 137 kmh then you bet I'll try to get that limiter switched off somehow!

I wonder if changing to taller rear sprocket would make it possible to go at higher speeds, or the speedo would still cut it at the same speed...

Another thing to have in mind in regard to the top speed - at those speeds the bike starts to feel too light. Not that it loses balance or wobbles or anything similar, but you just want more weight for more planted feel. Imagine going 100 kmh on a bicycle - it would be scary not because of the speed but because of absence of weight to keep you planted on road.
A bigger windscreen should help a lot in high speeds to push the bike more downwards.

It also felt that at the high speeds and higher revs that the engine could benefit from more air. I didn't have this feeling before with stock ECU map, it felt there's enough air. it could be that Kiirus ECU map makes more power and also needs more air.
Motozone guys sell BMC air filter for Rs 3,500, and I might go for it. However, I want first to figure out if it's worth shortening the air pipe that goes out of air box. It's very long at 30-40 cm, which reduces the intake of air.

----consecutive posts auto-merged-----

I had exactly the same problem.
in fact, still having it...

I did a service recently and told them about it. They replaced the fuel filter, which they said was very dirty. But they said the FI was OK.
But my bike is still heating up more and faster now than in April.

From your post and from my experience it seems like the only thing that can be faulty is the fuel injectors.
I will do another service again in a week and will ask about the FI, and if they say it's OK then I'll ask for replacement.
I did few tankfuls of Shell Super but haven't noticed any change.

Re: KTM 200 Duke

ˆˆ This is an initial experience right?? It is still inconclusive.. You have just mentioned a stronger mid range and the top end has remained the same right? so i guess your acceleration has slightly improved right? I suggest try the 40T rear sprocket mod along with installing the MRA windshield... if and when the roads permit attempting a speed run will give you an idea about the change in the bike's behaviour. One thing is for sure, the bike's gearing will become taller compared to 43/42T stock so you will have to get used to that. once you get a hang of the peak power build at each gear then you will love the way your bike reaches the top end cross the 137 kmph barrier.


Keep the rev limiter being switched off as a last resort... first see what sprocketing change induces to your bike's behaviour...

All the best mate..

Cheers,

Re: KTM 200 Duke

Well, this is a 3 days experience with LOTS of riding in city and few hours of highway. I wouldn't call it inconclusive.

Lows and mids are quite stronger, so the acceleration isn't "slightly" better but considerably better.
The bike reaches any speed now quicker than before. But smoother in the same time.

The top end seems to me to have the same power. Which I'm not surprised at all because stock Duke has very strong top end but weaker lows and mids.
It looks like the top in stock Duke is already at the engine's max.
HOWEVER, the rev limiter is moved higher in Kiirus ECU, so there's MORE top end to play with.

Overall, I'm very happy with Kiirus ECU. For Rs 9k you get a stronger and faster Duke, AND much smoother engine that can putter along in low rpms without any stuttering.

About the 40T sprocket and loss of acceleration - you have to take into account that with Kiirus ECU you get stronger lows and mids, so putting a 40T sprocket will just bring the acceleration to the same level as stock Duke.
But even then, not really so! Why? Because "acceleration" isn't how fast you build up the rpms but how fast you build up the speed.

Let me clarify. For example, with 43T you'll reach 7000 rpm in a same time as you reach 6500 rpm with 40T sprocket. So, 40T is slower? No. At 6500 rpm with 40T sprocket you'll be going the exact speed as at 7000 rpm with 43T sprocket.
So, while the revs will build slower with 40T I think the actual speed/acceleration will stay pretty much the same.
This, of course, has its limits - if you put a MUCH taller sprocket then the actual acceleration WILL reduce.
Kiirus ECU map would just boost the acceleration no matter what sprocket - the engine gives more power, regardless of sprocket.

So, I'm pretty sure that one would have faster acceleration with 40T sprocket and Kiirus ECU than stock 43/42T sprocket and stock ECU. And not even to mention the top speed, which would increase a lot with taller sprocket...
So, it's a win-win.

Please note that putting a taller pocket to weaker engine reduces acceleration more than putting a taller sprocket on a more powerful engine.
So putting a talker sprocket with Kiirus ECU makes more sense than putting a taller sprocket with stock ECU...

However, it could easily happen that next week when I try the 40T sprocket I come back here and take back everything I just wrote.
We won't know for sure until we try. Which I will.

But anyway - the sure fact is that you can't compare a stock and Kiirus ECU Dukes regardless of sprockets they have - Kiirus ECU simply gives more power at any rpm, so it'll accelerate faster and will leave the stock Duke behind.

Re: KTM 200 Duke

Hi Serge, I agree with your experience. I too have been riding a lot since last 2-3 days. My experience is same as your. Stronger bottom end and mid range. Well honestly, I always found bottom end and midrange quite good for a stock D200, however remap has made it even stronger.

I couldn't agree more with when you said, it is now possible to stay on each gear longer now, I can putter along in 3rd gear from as low as 10 till the redline without any lugging.

It seems this little motor hasn't heard about knocking, no matter how hard I try, I just cant get it to knock. I am not complaining

I also could register 125 momentarily on Palm Beach Road yesterday, but due to winds could not go further. Have to check again on a sunny day.

However, now it is very fast, and the turbine like noise that it makes when revving hard, I just love it.

Re: KTM 200 Duke

I am glad that the performance is at par with what you had expected. Forgive me for being slightly a critic but my hot roding experience has taught me not to recommend nor give out all positive reviews till the extensive tests have been carried out with the aftermarket performance kits. I suggest try the 40T first, get the experience about the increase/loss in acceleration and then do report back about the after effects.

@Chinmaykar: If possible please do check out the spark plug reading when going for higher altitude rides... should give you a fair idea of what is happening inside the engine. From the initial reports of rider Splus, as of now my guess is KIIRIUS has made the fuelling at the low and mid range much richer than the stock map hence, the profound effects.

Thank you gentlemen, I am learning a lot from you.
