2010 FE390 fuel filter issues

A growing number of Fe390s owners experience clogged fuel screens in the tank. Happened on mine after 2hrs.

Here is the Thumpertalk link to the full tread. But this is the symptom:
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.

And the cure:
Bendbiker was right!
Just talked to the Dealer. He inspected the fuel filter after I told him about the experience of Bendbiker. The filter was completely clogged with a white paper-mache like substance. He cleaned it out and apparently the bike was immediately completely different. He found the same issue on the other 390 he had. He contacted Husaberg and they are looking into the issue. The two bikes affected were 8 units apart on the assembly line. There is a good chance that other bikes may be affected as well. The dealer (and others on this form) have noted that the 390 needs a tiny bit of throttle to start. Apparently, after the filter was cleaned the bike started easily with no throttle.
I suggest that everyone should consider cleaning their fuel filter, especially if you need a touch of throttle to start your bike.
I will ride tomorrow and give you a ride report.
Thanks for all the help, I Hope this solves the problem.

Yup - fairly classic symptoms of severe fuel delivery problems.

I had a BMW GS that would starve for fuel at high speeds. Checked the petcocks and the input filters were rotted off and clogged (previous owner had not maintained them).
 
Filter junk looks like salt or surgar
Someone whats to make the new Husaberg look bad
Has to be a full blown terrorist attack against The great Husaberg :cuss:
 
I very much hope somebody takes the time to analyze the material. I'm very curious to know what it is.
 
Yeah , could have been a disgruntled customer in the shop just putting a bit of sugar in the tank or possibly one of those packs to keeps the moisture low (silica gel)..
 
It could also be left over plastic particles from the molding of the tank. Some molding processes use very small plastic particles as the raw material.

yeah +1 on that
 
A friend of mine have a fe390 just like mine and he was experienced problems with the motorcycle, he remove the fuel pump and the filter was cloged with the same sustance, my 390 was working perfect but I perform the filter check to see how it was and found the same sustance in the filter but withuot any problems of fuel delivery.
by the way do any one try to take out a part like a propeler that it`s inside of the exhaust? I don`t know if is a spark arrestor
 
I finally opened up my tank tonight and there was nothing on the filter. The bike is a 2010 FE390 that has about 15 hours on it. Does this mean I shouldn't be seeing the infamous filter gunk then? The bike is a US model...
 
If you haven't seen it by now you probably won't. I didn't see it. I don't think it is limited to any one model.
 
Hi guys,


The same thing happened to my KTM690R: The fuel filter was clogged with this substance. It turned out that it has something to do with the type of gas we use here in the Netherlands, Europe. I've lived in the U.S. for awhile, but I can't remember if there's a possibility to choose between a normal lead-free gas or a more refined type of it. It seems that in the normal type of lead-free gas, there are little particles, that get stuck to the fuel filter and make it clog.

Ever since I know this I put the more expensive type of gas in my KTM and use it also for my Husaberg. Up 'til now I'm okay.

Any gasoline that has Ethanol in it needs to be treated.

It has been discovered that a micro organism lives in Ethanol gasoline. Not surprising since Diesel gets algae in it.

The one product I know of that takes care of this problem is Star Tron-the blue stuff.

I just had a fuel pressure regulator fail open (low pressure) on a low hour 09 570. When I pulled the pressure regulator out it had a bunch of this white residue on the outside, and the spring loading piston/plunger was seized in place.

It's also a good idea to run about a half dose of a fuel additive like Lucas gasoline/diesel fuel treatment to keep things clean and lubricated.
