Why can't my 570S be reliable

Bought my new 2011 FE-570S back in October. Right out of the box, I had trouble starting this thing when it was hot. Apparently, it was running lean so when I took it in for the first service, the ECU was re-flashed and that seemed to fix the starting problem and the backfiring issue that appeared after I put my FMF pipe on it. I also de-smogged it and put a Ballistic battery in it. I didn't get to ride it much after I got it out of the shop from the first service and took it to Big Bend 3 weeks later. On the first day, we got 70 miles in the desert and it just stopped. It would start but would not take any throttle. Trip ruined.

Took it to the dealer and they checked everything and the only thing they could determine was my Ballistic battery was bad (I don't think so) and that my TPS was off. I picked up the bike and rode 300 miles the next day without incident.
Took it home (about a 3 hour drive) and when I pulled it off the truck, it was very difficult to start but it did start.

A couple of days later, rode 50 pavement miles to the trails and rode around for 2 hours. On my last lap, it did the same thing it did in Big Bend. I was cruising along and suddenly it would not take throttle inputs. I limped it back to the trail head and it would not start from that point on. Another day ruined.

Brought it home, and over the course of 3 weeks, tried to start it and it would not start. Took the battery out and swapped it with another battery but it made no difference. Out of sheer frustration, I ordered a CA fuel pump even thought I didn't think that was the issue. I stripped the bike down to it's sub frame and replaced the fuel pump. While I was at it, I disconnected all of the electrical connections I could get to and put them back together with di-electric grease. I put it all back together and it fired right up! Went riding the next day without incident and the bike ran great!

Pulled the bike out yesterday and had a hell of a time starting it. It turns over fine but as I am trying to start it, it is back firing so much the exhaust pipe is getting hot even though the bike hasn't started. Finally got it started and went on about my way. Bike ran great! I stopped and talked with another rider for about 5 minutes. It started back up but the other rider commented that it should have started quicker. Anyway, off I went. Rode for another hour or so and ran into another rider so we stopped and talked for about 20 minutes. Got ready to leave and the bike would not start. Same deal. Backfiring while trying to start, can smell gas, but it won't budge. After trying for 20 minutes, we finally gave up and hauled the bike home. Another outing ruined.

As of right now, it will not start. It turns over fine. It just won't start. This is what I know about the bike right now:

Fuel pump is working properly.
The injector is not clogged.
The update on the fuel screens has been done.
I am getting spark.
I am getting fuel based on smelling it.
The gas is new.
I have used StarTron fuel treatment from the first day I owned it due to crappy US corn fuel.


Any ideas?? I am desperate. My dealer is not close nor do I have a lot of faith in their abilities.

Re: Why can't my 570S be reliable

Steve,
My humble opinion is that you might consider telling your story to the Husaberg equivalent of a regional service representative. Your bike is still under warranty, I take it, and while that's still the case I think you should bypass the dealer (he's done his bit) and take your case to the next higher level.

Re: Why can't my 570S be reliable

I'm thinking the injector is leaking down. That would match your current symptoms.

Re: Why can't my 570S be reliable

When the bike will not fire and you can smell gas are you getting a good and reliable spark at the plug?
Is the fuel wetting the plug when this happens? If you are getting a good consistent spark and the plug is wet it could be as berger has suggested.

Re: Why can't my 570S be reliable

Thank you for the response.

Ruger, the bike is technically out of warranty by a few weeks but when I spoke to the dealer, he said that it didn't matter as he would do it as an ongoing issue. To me, it is not my dealer's willingness to help, it is more their inability or ineptness. I am probably going to take it to them one more time on Saturday and let them try again. After that, I will take it to the next step.

mrt10x, I still have a ways to go here in Texas before I can start talking lemon laws. Trust me, it has crossed my mind.

berger, please explain the injector leaking down. I don't know what that means or how to test for it. I am not a great mechanic and am learning as I go. Can you please give me more information on what that means or where I could go to read about it. I will tell you this about the injector that has my buddy who know a LOT about bikes and cars: the injector has no resistance when I put an ohm meter on it. I tested a friend's clogged injector he took off his 2010 and it ohm'd out at 10.3. I posted something here but got no responses to my question. When I told this to the dealer, he said he pulled one of the shelf new and it has 0 resistance. According to my buddy, this is not possible. Any words of wisdom??

pegscraper, the plug is 6 riding hours old. When I pull the plug (which is a bitch) it seems to spark just fine. I will have to check and see if the plug is wet. As far as reliable spark, how should I be checking?? I can see it arcing but again my limited knowledge comes in and bites me.

Injector leak down. The injector pintle is not sealing, either due to corrosion or debris. Think of it as sticking open. If you can remove the injector and keep it hooked to the fuel line, run the pump to get fuel pressure and see if the fuel injector leaks any fuel. Make sure to have the injector electrical connector unplugged. You may have to watch it for a few minutes.

This may sound silly, but to me it sounds like the auto decompressor is screwing up. It runs fine because the decompressor is not in action once the engine starts. The whole backfiring out the exhaust port sounds like the decompressor is sticking causing a low compression issue and the hard starting.

Like I said, I could be wrong, but I'd do a compression when the bike is refusing to start and see if you have any compression and determine if that is the issue.

Just a thought.

Re: Why can't my 570S be reliable

Berger: testing the injector for leak down sounds fairly strait forward. I will pull it this weekend and see if that indeed is the case. Thank you for explaining.

Re: Why can't my 570S be reliable

Could be ethanol in the fuel. Try to find a fuel source without ethanol. In Ontario, Canada they introduced 10% enthanol blend in most grades of fuels without telling anyone. My old DRZ400E all of sudden ran like crap (bad starting, sluggish performance, no zip), could not figure out why. I took a sample of the premium blend I was using, doing a simple ethanol test, turns out the premium gas now had ethanol, and it was over 15% (legally only supposed to have 10%)

Two retailers do not put ethanol in thier premium gas, I tested this to be true. I rode the bike with the old gas, got off drained it out and dumped it into the lawn mower, put in real gas, and the difference was night and day, bike was easy to start, ran smoother and had its snap back.
