I'm hoping that you post whether any of this helped your situation. I have a 2010 390 with the subframe tank and the green fuel line ruptured along with a shut off valve that melted from exhaust heat. I replaced the fuel line and discarded the shut off valve as I felt there was really no need for it. Now the bike doesn't want to idle and seems starved for fuel at mid-WOT. I can't get the bike above 70 mph. Similar symptoms to yours and stumped as to what I may have done wrong. How many fuel filters should there be along the fuel route? It almost feels like it may have a clogged filter?

Make sure ignition coil is earthed correctly- have seen loose bolts or when frame has been painted make the earth less than perfect. Make sure it's clean metal underneath coil mounts. Maybe check coil resistance specs while you're there.

Hi All,

I've cleaned the coil earths and replaced the coil for a new one. Still no results... The bike keeps stalling when I twist the throttle. I've also disconnected the MAP sensor but this didn't help either. I've made 2 videos about the problem.




Anymore suggestions are more than welcome!

Kind regards,

Cornť

Shot in the dark. The throttle body has a cold start knob in is normal out is cold start. Did you check the earth by the battery it’s at the frame. Maybe you should try a module off a other bike. Good Luck

Check the resistance of the the spark plug cap you mentioned you changed it but itís good to check the resistance. Mine had a similar stall out issue

Hi Rainerio,

I've checked the cold start knob but this didn't solve the problem.
I've also sanded down one earth point near the battery, how many are there?
Unfortunately I don't know where I could borrow an other module...

Kind regards,

Hi Cambo,

I will check it and post the result, thanks for the tip!

Kind regards,

Hi all,

I've checked the MAP sensor for any faults but it seems to work as it should. But I've discovered something else.
The sparkplug does not spark when you fully twist the throttle!
It does spark normaly but the spark cuts out as soon as you fully twist the throttle. I've checked the values of the TPS but these where stable, even when the throttle was fully open.
Does anyone has any thoughts on this?
Please let me know!

Kind regards,

Cor

well something is either not creating the spark = the coil

or it is breaking the spark down; the plug, the plug cap, the HT lead.

these are my thoughts on it.

there's the small possibility the mains are going and the pulse coils are too far away from the flywheel at the moment that you want a spark?

regards

Sounds like the TPS could be faulty? It's just a rheostat, check that as you open the throttle, the voltage goes down smoothly. If it jumps around or drops off it's probably dodgy. That does not explain spark issue, though...
Check all connectors to tip sensor, manifold pessure sensor, and especially the big connector into the ECU- make sure it's spotlessly clean, no corrosion or even dust, can cause all sorts of intermittent problems.

Lightbulb Fixed!

Hi all,

I've finaly fixed the mighty Husaberg!
After checking the timing, I noticed that de spark plug was cracked.
I've also cleaned a couple connectors which are sitting underneath the tank. These connectors came from the stator and were very dirty. Plenty of dirt and mud.
I've reÔnstalled the old spark plug (left one) and cleaned the connectors. This did the trick. No more bogging, no more stalling, just pure fun. The Berg runs like new. It ought to be since most parts are new

Thanks for all the tips.

Kind regards,

Cor
