Brand New 390 dying!! Help

2010 FE 390, 2 days old. Aggressive Map setting, dealer told me they removed something from the muffler to improve power, not sure what that was. Emissions or noise control likely.
2 rides so far. Yesterday, riding gently for break-in period, I noticed it start to hesitate and bog down after an hour of riding. Problem associated with some back-firing. seemed to go away quickly and feel normal after. Problem re-occurred a few times and actually stalled 2-3 times. Started after the stalls no problem and actually felt fine between stalls. I headed home so I wouldn't get stuck in the woods. Problem seemed to go away on the way home (faster riding).
Changed the oil and filters last night.
Rode today and problem much worse. No crazy riding, low speed 1 or 2nd gear woods riding, really taking it easy on the bike still, no hard reving. Problem started an hour into the ride. hesitating, and eventually stalling, more back firing before stall. If I waited a few minutes, would start relatively easily and drive for 30 seconds then stall again. Seemed to ride fine for those 30 seconds then bog down. The longer I went, the worse it got. Eventually the interval between stalls got shorter and shorter. I'm not certain but seems like I could get a longer ride if I waited longer after the stall and let it cool down more. I actually started spraying water on the header to cool it down faster, seemed to help but not absolutely sure.
If the bike is over-heating (not certain that it is) seems unusual to me. Didn't feel particularly hot and it is only 5 degrees Celsius outside (winter in Canada).
Any thoughts? Cooling system? Fuel injection? Fuel filter (is there one on this bike)?
Any help appreciated. I'm hoping this is going to be an easy fix. I'm trying to avoid going to the dealer because it is a 2 hour drive each way. :cry:

Thanks Woodsrooster, I'll try that but I doubt it. I unscrewed the gas cap several times today and the bike still stalled after about 30 seconds.

Any other ideas out there? :cry:

I just went over a few things.
Fuel line connector snaps solid.
Fuel pump normal
air filter clean
gas tank vent normal, easy flow of air

I noticed my header pipe is golden yellow, not silver stainless like in the manual picture. Is this an indication of overheating? I actually noticed it was yellow like that when I bought it.

Thanks for the help. The bike is at the dealer now. dealer was very helpful and concerned, claimed this was the first 2009-2010 he has had returned. Unfortunately, he is unable to connect to the computer. He has 5 390's in stock and non of them are recognized by the Husaberg diagnostics? Husaberg has sent him a few software patches, still not working. !!
Meanwhile I am without bike and still no answer as to why this is happening.
PS. my bike had the newest competition mapping already.
PSS. Spark plug will be a good place to look, i agree. Thanks DaleEO. Would explain how the problem only starts when the engine gets warm.
Will keep you posted.

Just talked to dealer. Apparently a software issue with the dealers computer caused the problem. The bike and the base computer were not communicating properly. When the dealer installed the competition map prior to my purchase, it didn't install it properly. It resulted in an auto-shut down every time the temp got up a bit.
I now have a proper install of the newest (just released) map and apparently the bike is much better. Dealer is bringing the bike back to me asap.
Greatly relieved!

Just got back from my first ride since it came back from the dealer.

Still doing it!!! :cuss:


Seems to go longer before it happens and required a hotter engine before it quit, but it is basically the same. It was about 5 degrees Celsius (just above freezing) outside so there is no excuse for this to be happening. The riding was tight woods single track, which is admittedly where engines get hot because of the low speeds but this is really no excuse. I had only been in the tight section for about 10 or 15 minutes before she started to die. took a long time to get out of the woods once it started as I could only ride for about 15 to 30 seconds before it quit. I eventually got to a creek and splashed some water on the rads and header. This helped. Interestingly the engine did not seem very hot. Steam came off the header pipe with the first few splashes but that was it. It certainly was not overheated. It still died a few more times after the water even thought I was on open roads from there home. Should have been nice and cool by then.

Talked to dealer, He is going to talk to Husaberg and pick up the bike to figure out what is going on. Interestingly, the dealer rode one of his other 390s 2 days ago with the original map in it (not the updated one he recently put in my bike) and he had the same problem.

Any further ideas? How is it that only this dealer's bikes seem to be having this trouble? Could it be bad gas. I'm going to get bad gas soon it I can't get this fixed. :angry:

Dealer drove 2 hours to get here today and we think we solved the problem. He had the same problem with a bike he had already flashed to the newest map. When he went over the map after riding it turns out the new map was not there and it was running on the old 'Green' map. He reflashed a different way and then it actually flashed properly.
He drove up to check my bike and sure enough, it still had the 'green' map installed. He did the flash with a different series of steps and this time the map is actually there. :cheers:
I'll ride tomorrow and hopefully it works. I guess it was a problem with the way he was using the software. I am impressed with his dedication and commitment to fixing the problem. He was really great. Will keep you posted.

I'm in Squamish, BC. My dealer is International Motorsports in Delta, BC. It was the owner of the shop the drove up here (2 hours each way). He was really great.
