ECU: Combustion Chamber Malfunction (FS570)
 
Hi all,

Have my FS 570 '10 for a bit over 6 weeks now and i've totalled around 2500km on it since then.

All the maintenance has been done when due.

For 600km now, the engine has stopped running 6 times already. This happens when the engine is warm and when i'm Giving gas. The more i give gas the worse it gets, till it finally collapses. Now after the engine dies, i cant start it again. However, if i leave it at rest for 15min. it will start again. I took this to the dealer and the ECU mentions this code: combustion chamber malfunction. They dont know what it means..
I think they'll look into it with KTM but they told me it would take approx. 2 weeks

Anybody for help?

Ktm have had problems with their spark plugs recently. they crack in the white stuff, hairline fracture.
Might not be a problem till theyget warmed up.

so all the symptoms i mentioned match the diagnostic of a defect spark plug?

Could be a spark plug, easy enough to check. I would think it's a fuel pump issue the way you describe it.

Hold on, im going to detail what happens so you have a better idea.

Most of the times its like this: Stop and Idle in neutral or with clutch in. 1st gear, gas n slow release of clutch, doesnt rev up and stumbles/coughs, i give more gas to aid the stumbling and it dies even faster. At that moment, if i clutch it in again or put it in neutral, it idles like 2 more seconds and then it dies.

It happened like this too: 2nd gear driving, wanting to reach 3rd gear so more gas to rev it up, however the engine just kills itself as i give more gas, till death.

Sounds like the fuel pump seizing, low fuel pressure, wont accel and finally dies when the pump seizes. Wait a few minutes for the pump to cool and it runs again.
Can you hear the fuel pump run when you try to restart it after it stalls?

If you just tap the start button you will hear a buzzing sound for a few seconds. Thats the fuel pump running.

ok got the sound, yes the fuel pump works when it doesnt start.

so who of husaberg could explain what the code means?
Or could it be a multitude of things?

This might sound stupid, but have you checked your battery terminals? My 570 under acceleration sometimes just shut down down with loud bang coming from under seat. Loose terminals caused this and almost same thing happened to my friend. Bike wouldn't start anymore, loose terminals caused that also.

Fuel pump is also issue with these bikes...have you checked your fuel pressure?
