Re: Aftermarket fuel pump

Davo - thanks for that link. I did a search, but somehow missed that thread. Next time I pull the tank I will do some probing.

No back to main topic of this thread - fuel pumps...

Re: Aftermarket fuel pump

Okay--got my CA Cycleworks pump installed per some of the great directions here. Used the Oetiker clamps, cut the stock fuel line to release from the original pump, etc.

Ran a really nasty Harescramble race in 95 degree heat, high humidity and so much dust I could barely see. I wish I had fared as well as my bike did. It ran flawlessly and re-started numerous times while fully heat-soaked. Can't say the same for the rider

FWIW the bike has no tank insulation, no fan, etc.

FYI for anyone with the CA Cycleworks pump:

Got to the trail yesterday and my '10 FE570 wouldn't start. Sure enough the end of the submersible fuel hose had popped off the un-barbed end of the CA Cycleworks pump. I figured that would happen at some point. So I roughed up the nipple and tried to flare it out a little bit as I'd seen someone do in another thread. Also went a little tighter on the FI camp and attempted t safety wire the hose to the pump housing. The bike starts and runs fine now. Hopefully I've fixed this and won't be stuck in the parking lot (or out on the trail) again.

My bad for not attaching it right the first time, hopefully this doens't happen too often, otherwise the pump is working great.

Re: Aftermarket fuel pump

Took me 2010 FE450 out this Turkey Day weekend to do some riding and was hit with the bad fuel pump issue. Bike would run for a few miles and then crap out. It wouldn't start again until it completely cooled down.

Before I talk to my dealer, are the new fuel pumps KTM is supplying fixed or should I just get a CA Cycleworks pump and be done with it?

Re: Aftermarket fuel pump

I installed the CA Cycleworks pump (which was a pain) while I waited for the KTM replacement (they were on back order at the time). I now have the CA Cycleworks as a spare.

Re: Aftermarket fuel pump

Thanks. I just ordered the aftermarket pump. I need some experience with removing the tank anyway... LOL

Re: Aftermarket fuel pump

OH boy. It took me over an hour to read all the postings for fuel issues. I just bought a 2011 570 FE and have put in 40 miles new. Put a new slip on and Vortex ECU. Started the bike and ran for a few then the pump stops. I am so bummed knowing and hearing the pain you guys share with this issue and now I have to do the same. I am not sure or confident about the Husaberg 570 FE being stable and trusting her to make it back to camp. Are your issues resolved on your bikes? Geez, I thought I was making head way with some mods. I just bought this bike less than two weeks ago... Been a yamaha rider since 1981 with no bike issues. I hate to put the 570 for sale. Please advise.

Re: Aftermarket fuel pump

So, yes there is a fuel pump issue... you already know that. Supposedly it's related to the ethanol used in the USA gasoline. Maybe, maybe not. The original pump was made in China and so is the CA Cycleworks pump. I'm told the new pump from Husaberg is now made in Italy. Never verified that. Now my story.... My pump didn't fail but as a precaution I installed one of the early CA Cycleworks pumps. This is the one without the nipple barb on it's pressure output. Well, it failed. Turned out that the supplier for CA Cycleworks had some bad ones. CA Cycleworks supported me well and sent me their upgraded and tested one that now has a barb on the nipple. It's been running fine all this season. Will it hang in there?... hope so. CA Cycleworks tells me it will.
As far as selling the FE570, it's you're call. My son rides a Yamaha WR450. We've had to work on it too - one electrical problem and some carb work. But the difference between riding the two is pretty significant. When we switch bikes I can't get my son off the Husaberg and I can't wait to get back on it! It's awesome.
I haven't searched, but why would you change the ECU? I'm in Colorado and my 2009 berg's injection is perfect. I've ridden it in the Wisconsin and up at 14,000' here.

Re: Aftermarket fuel pump

After some time original fuel pump, caused by overheating from exhaust pipe, will die. Not instantly, period of cooling will be longer and longer, but changing it its inevitable. It's not question of US ethanol or whatever, it happen here in Europe on 390, 450 and 570. No exceptions. One year ago I bought new original pump and works fine. Based on the serial number we found out that same pump have been used by Piaggio Group (Beverly 300-500, Nexus 300-500, Scarabeo...). First "Piaggio" pump have been instaled few weeks ago on 450 and it works OK.
