Re: KTM 200 Duke

The bore that joel provides is someother bore which is oversized. When oversizing they lose their original strenght and they can't match the precision of factory bore. Minute imperfections will be there which will end up in loss of compression and piston rings busting out. Also it results in microscopic cracks in bore which becomes big when hot and thus coolant leaks into engine oil bay.

Btw someone pointed out about volumetric efficiency. While a guy like Joel can do these calculations,don't you think KTM would have done several calculations like this?? They ended up with proper bore x stroke after several R&D. Just think

Next your ECU is not designed to compensate for this much amount of extra cc ( even closed loop). This results in engine running very lean ( reason why you get awsm mileage even with big bore) your gaskets gets blown often due to this.

Imo FI bikes are way too much complicated than you think. Even a small change here and there will affect the entire system unlike carb bikes. ( Maybe this is the reason someone is happy with his pulsar mod) Just don't mess it up. Want power?? Sell it and get 390.

Re: KTM 200 Duke

Met an accident yesterday. Its very sad to say that the front of the bike is kaput. The headlight assembly went missing including the display etc. The handlebars are bent horribly...the front alloys are broken completely ...the suspensions are bent. the radiator is bent too and coolant flowed out on the spot. Tank has several bruises too. The SVC guy says Oil case has a bent too and the crankase too.
Any ideas how much roughly this all will cost. ???.
And the frame might be bend too but that hasnt been checked out yet. Financial restrictions will refrain me back from replacing it. Ill have to mend it somehow. What Im wondering by what degree/extent will be the bike's austerity will be harmed even after i get the parts replaced and get it repaired.

Re: KTM 200 Duke

I agree with you about the machining part of the kits, but you as an informed customer should also take a look at that.
Also most racing builds run tighter tolerances than what comes in the factory. Machining has come far away in past few years and if you know the basics good results can be achieved from old machinery.

For FI part Joel is also providing a ECU with the mods. Anyone who is going for the mods without ECU is shooting himself in the foot.

About the design, KTM has to make a bike which works well from Greenland to Africa.Works on 87 octane with 5000kms service interval and made to a price.
They have to follow some rules for emissions as well. Look at KTMs off road bikes they are pretty much pushed to the limit from factory.Have service interval of few 100 hours and go through bores in a couple of thousand kms.

I would like to correct you, in EFI small changes here and there are better compensated rather than Carbs which require tuning.

I like modding and have tried a few things on my bikes, and talking from some practical hands on experience and what I have seen on other builds.

PS: I would like to clarify that I am not advertising Joel or his mods I am just saying there is scope for modification and you cant have everything, there are somethings which need to be taken extra care of.

I hope you are not hurt, I would suggest after so much damage it would be better to write off the bike and get a new one.
Because even after you repair it and pay the huge bill it wont be as good as it was.Also the SVC guys can never do a job as good as the factory.

Re: KTM 200 Duke

Sorry to hear about your accident. Looks like a very nasty accident. How are you? Going by the damages you mentioned, do you have an option of claiming Total Loss.

Even if you repair it, it wont give you the feel as earlier. There will be chronic issues.

Re: KTM 200 Duke

As per your assumption, duke 390 shudnt heat at all. But it does, more than 200.Its how performance engines are meamt to be, and thats the reason we have a liquid cooling system.

Re: KTM 200 Duke

You are just talking about the fueling part which carb cant adjust and even the ecu cant adjust ( you need a new ecu or remap). But there are several other sensors which measure various other quantities. Everything changes when you change and you never care about these,but ECU cares.

Re: KTM 200 Duke

I am not an expert and still learning so can you please explain the several other sensors and what changes with modifications to the ECU?

Re: KTM 200 Duke

Seems sarcastic!! Still,go through "The poweriouse fz 18 " thread. Am just telling whatever I read. Am a noob.

Re: KTM 200 Duke

Sorry to hear that mate. Hope you are all right.
From the description, it seems like the bike is totaled. it would be better to write it off and get however much you can from the insurance.

If the crankcase has a bend there is a chance that the crankshaft is bent too, which means probably other engine damage as well.

With engine damage and frame damage, fixing it will not give you the feel of the original.

From what I know below are approx prices for parts:
Forks ~ 16000
Wheel ~4000
Console ~6000
Radiator assembly and fan ~ 5500
If wheel is damaged badly, then the tires might need replacement too which is another 3500 or so.

Just adding up some of the parts that need replacement, it is more than 30,000. Now with other parts and labor charges I guess it will come up to or more than 50,000.

Re: KTM 200 Duke

Even i think so too... But it has to be repaired. Cant leaver her that way.

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

Accident was pretty gruesome but i am fine. Minor bruises only. But the bike suffered a lot. Cant let off the bike....cant. Its just me that i had never and probably wont sell the bikes i own ever... So reparing her up is the only option. Bill is huge. They gave an estimate of around 50K.

Re: KTM 200 Duke


Yaah the guy from SVC gave an estimate of around 50000. Crankcase has a dent. The guy said it will get replaced. I doubt and hope theres no crankshaft bend.

Re: KTM 200 Duke

Can someone give me the no of the outlet in Mumbai which sells engine ice pls? Admit had given me but I lost my phone yest

Re: KTM 200 Duke

There is just one outlet in Mumbai. The Guys name is Abbas. Number is there on 1st page of this thread. However, here is the number 98 20 068285

Re: KTM 200 Duke

Folks, i'm heading out to the track in a couple of weeks time. I want to harden up the rear suspension beforehand. Does anyone know how to do this (and if it can be done at home with the regular tools I might have)?

Re: KTM 200 Duke

Does BMC air filter affects the engine life at long term ?
Normally we used to replace the spark plug every 5000kms , if we replace it with NGK iridium one , what's the interval to change it .
