Vapor lock on 2010 390??

Way to go, JQ ...! And please pass along a major THANK YOU! to your dealer who was willing to share this information. Without that, we're just left guessing.JohnnyQuest said:
Hope this is the start of a real solution. Aka, higher-quality replacement fuel pumps.
Of course it still remains to see how to identify if you have an affected pump or not. And whether you can get a replacement pump.
Hope this doesn't turn into a big issue like the '08 cam/ADC issues on KTM EXC-R bikes. Ooof.

As of my last post, I have not had any inop fuel pump opportunities to chase.
Did run into one unit with an inconsistant short to ground black/yellow wire behind headlight that would cause a no fuel pump operation situation when it felt like it hot or cold, and a loose battery terminal that also caused a similar problem.

Hell yeah! Maybe I can win a new fuel pump.
I guess those of us that have had this happen will have to monitor this thread for any possible news from KTM/Husaberg regarding replacements? Maybe a dealer can inquire to find out if they plan on doing anything about it.
I talked to a guy on the line at the LBJ Harescramble yesterday who had the same issue as me and after working with his dealer in Wilkesboro, NC and Husaberg they replaced the whole tank assembly with pump. He now has 55+hours with no issues. I believe he said it took 7 trips to the dealer and getting Husaberg on the phone to get it finally worked out though.
Too bad I've blown half a race season trying to get this worked out...Time to get my dealer on the phone.

From my own personal experience with a completely different issue I would have to say that Husaberg stands behind its product and will make it right. Of course, it helps to have a top notch dealer on your side to interface with Husaberg. Good luck and keep the faith.
After originally posting this issue more than a few people seem to have the same problem with their bikes. Has anyone pinned this down? The last post I read about it someone said the fuel pump clearances were too tight on a small batch of pumps.Has this proven to be the case?Tasky say's he has a new pump on the way. I hope it solves the problem as it will not go away.I have been very busy for some time and took the bike out today for the first time in 4 months. I did not expect any problems since I installed the C4 fuel cool blanket and it was only about 40 deg.or so. I logged 25-30 miles of slimy single track.Flamed out 4 times after bogging and "ran out of fuel" once on a fire road.Maybe the cool temps helped because it always re-started right away without any "wait time". I was curious if there was another solution I missed that I could try while I wait for a new pump.
I have had zero problem sinc the new fuel pump. Mine started earlier that most anyone elses at 2 hours. Eventually it died completely and would not start at all. Before it died, I only had the issue when I stopped the motor after it was warm and then tried to restart it. It never died on me while riding.
Replacement FI Pumps: Aftermarket?
I registered cuz I just had to chime in and pose a question.
After the epic battle of the long-suffering owners who were finally made whole with replacement FI pumps, we now have this knowledge of what happened (bad run of too-tight pumps). But inevitably failures will occur with some owners who never see this thread, never get offered a replacement under warrenty, recall, TSB or whatever and will be faced with a $500 bill and an "oh-well."
I've witnessed that a lot of FI pump bodies are universal with only their mounting bits varying from one application to another, so is it possible that an aftermarket unit you could get from NAPA etc might fit in place of the KTM/Hbg OE unit? Has anybody tried to find such?
It would be nice to know that if you are in east podunk on a riding vacation far from home and dealer and you come off the mountian with a failure, you might be able to get a matching unit in a pinch from an autoparts store! and perhaps for $100...

Re: Replacement FI Pumps: Aftermarket?
I am thinking the same thing. It looks like a Bosch pump could be made to work if you tried. $100-150 sure beats $500.
I know I'll be trying to match smoething up if I ever have a pump go south.

Re: Replacement FI Pumps: Aftermarket?
In theory any EFI pump would work as long as it had the same flow rate (or better flow rate), was rated to operate at 48 ~ 54 PSI, and worked in with whatever Husaberg has designed for Fuel Surge issues.
The stock setup has the return Fuel line from the Fuel Pressure Regulator connecting back to the stock pump which is a little confusing to me. Normally this return Fuel line just goes back into the Fuel Tank (or Surge Tank)
Maybe Husaberg have some sneaky fuel surge design in the stock Fuel Pump setup?
I will take a look if I ever get around to installing my 70 Degree tank.

As per the micro film and the ktm part numbers the 350sxf uses the exact same pump and you can get the ktm version for 400
sorry for digging this thread up but my 2010 450 ( only done 1200kms) has been having fuel pump issue's where it it will stall whilst riding and then not start ...Both rides it has happened have been cool days and the bike was not very hot at all ( I run a fan abd profill fuel sock ) .....
today when it stalled There was No fuel pump noise at all ....Left it for 20min and then it started but stalled after a 10 seconds....left ot for another 10 mins whilsy checking wires etc....test it and it started road to friends house I was riding with and said my goodbyes started it up when to take off and it stalled again and fuel pump was not coming on .... ..
Connected a multimeter to the fuel pump terminal near the airfiter and It was going up to about 11.5 volts when kicking over ...reconnected the terminal and bike would not start at all tried for about 40 miutes and fuel pump would not come on so the berg is having a sleepover at a mates place and I had to g a lift home :angry: .....so there is power getting to the fuel pump but the pump no work ....
looks as if the pump is rooted but i'm no expert ...is there way to definitively test that the fuel pump is faulty .....

You can also check this post by DaleEO as the push on electrical terminals on the Fuel Pump may be loose:
DaleEO's Fuel pump failure and fix
You can follow my wiring diagram if you are checking for power and earth at the Fuel Pump.
If you want, you can check the resistance of the Fuel Pump with the multi meter switched to resistance (Ohms). The original problem with the fuel pump is the pump jams and locks (I think?), so measuring the resistance wont show the problem. If it is a connector problem inside the tank on the Fuel Pump the resistance would show Open Circuit or very high resistance.
Fuel Pump Resistance at: 20 °C (68 °F) = 1.0 ~ 1.8 ?
In this picture, just to the right of the Orange component on the ECU board is a little black/white square. That is the Fuel Pump Relay internal to the ECU.

Thanks for the info Davo ...
It looks as if my Dealer is going to replace the pump under warranty ....They have had a few show similar symptoms and once a pump starts with this problem he says that it will eventually stop working altogether.....I will also get him to fit the fuel pump profill filter as well ....will post back up with the outcome
