I would suggest taking it out for a ride and carrying a can of choke/throttle body cleaner, perhaps some starter fluid. When the bike stalls and wont restart quickly remove the seat and air filter. Spray some fluid into the throttle body and see if the bike will start. This will at least determine if it is electrical or fuel related.
 
they're taking it in this thursday for some 'proper' testing...
as soon as i have it back, ill let you all know what went wrong, for the second time.
thanks for your advice berger!
 
Wow, what a lemon 570 you have there.

Seriously, that sucks... Wiring harness / ECU problems maybe? Can't be that bad mechanical fault there.
 
so this is the newsflash:

They have finished their work on the bike. Apparently they took it apart to see what was wrong and found an electric wire that had been stripped of its insulation due to vibrations of engine against other metal parts.
According to their mechanic, this touching of the electric wire with metal parts caused the irritating situation of shutting down etc..

Does this sound plausible? Is anyone familiar with such issues?

I will get it back tomorrow and we'll see after some driving if the problem has been resolved
 
Very possible. Could you get the exact location and wire color of the short from your mechanic? It may help someone else in the future.

Sounds plausible. Crazyted had a good post on a wire worn through and shorting out up near the top of the shock. He wrapped the loom in an old inner tube.
Here is his post:

okay ill ask for the Exact location of the wire and color, but they already told me they couldnt figure out where the wire headed or what its purpose was. Also, maybe they took pictures..i'll hear from him tomorrow.

I got the bike back today. It rode fine....but the headlight is flashing intermittently (stronger/weaker) when its on normal position. Its independant of throttle activation.. A problem with the electric wire or relay im guessing..? When its positioned on stronger light there's no issue.

Im very happy to have it back however, wheelies on these new rain tires seem to be a lot easier to hold up...strange

How can they even suggest the problem is fixed when they dont even know where the wire goes or what it does??
Regardless if the problem is fixed, it sounds like it's time to find another mechanic.
 
here we go again.. problem continues showing up

it just sounds to me like i need a new bike.. cuz this one is F'ed up and yes berger my mechanics are probably F'ed up as well
 
Doesn't sound good. :(

So what did they even do to your bike? I would put completely new harness in the bike. There really ain't that much wires running in the bike and that would minimize alot of your problems. Maybe new battery also.

headlight flashing might indicate blown or faulty rectifier problem. Check your stator and rectifier condinition also.

Man I wish I could help you with your bike. I kinda like solving electric problems as I am electrician myself.
 
Finland aint so far away from Belgium my friend :)

All kidding aside, im calling them later today to see what they will come up with this time...

To berger: changing mechanics isn't much of an option to me, as I've bought the bike from this dealer and the other dealers are located much further away and will probably be less 'eager' to help out on this warranty issue, since im not one of their clients and their wages will be paid much less by KTM for doing the work

You are not alone, it is that way everywhere.

Again, I recommend riding with some starting fluid to determine if it is a fuel or ignition issue. This will essentially cut your diagnosis in half.

seems like im def not the only one..

someone here in belgium said he had the same thing and they replaced the 'camshaft' and it fixed the issue....-??

as per precaution, ill have the fan kit installed as well...allthough its even happening under 5°C conditions..


BUT I HOPE THEY'LL REPLACE THE FUEL PUMP, THE INJECTOR, AND CHECK UP ON BATTERY AND ALL WIRES
 
A mechanic of good reputation tells me this issue is known to practically all 2010 570 models, because of the overheating of the injection module because of it's placement just above the cylinder °70. As soon as it stops moving, the heat makes the injection go awry and thus it stalls. Nothing to do about it except isolate between, pour in better coolant, open up silencer to improve flow and reduce heat, install ventilator kit.


After talking with KTM technical rep, my dealer told me the problem is due to overheating but only because i 'STOP' the engine when I know that I wont drive and idle for more then 30seconds (red light). According to him, when this happens, the heat keeps building up and when I restart the ECU reads 'built up' temperature information and then shuts off preventively untill the temperatures read normal again. The ecu then mentions this as a 'fault', hence the combustion chamber malfunction code.

So my dealer told me to test if the engine would stall If i dont touch the on/off switch at stops.-, which I will do tonight at a nearby parking lot.

The vent kit is coming on friday. Ill have more info by tomorrow i guess...

Very interesting. It must be a European thing. Between running the lean emmissions mapping and catalyist, the bikes must run hotter than the US bikes.
 
so far i've driven for 30minutes slowly and stopped for a min here and there, without shutting the engine down
 
to continue this stupid story:

they've installed the ventilator kit and when they tried to start it, it failed to work, again (same issue)

they sprayed some of that stuff Berger mentioned in the air filter and it fired up briefly but then died.

After 30minutes, it started again.


From another dealer, i've learned that he is 100% sure the problem comes from the camshaft (something decompression something problem when warm). He's fixed it several times already..

so this week we'll see what we can do about it....
 
so finally this ktm rep approves the camshaft replacement and seemingly acknowledges that some FS570 models have had issues with it...

however, this will not be done swiftly, first my dealer has to take out the existing camshaft, measure whats wrong with it, give feedback to KTM, then if KTM says its faulty, they order a new one, and afterwards they install it. This will take approx 10days.

The positive is this supposedly really prevents the problem from happening again
