09 FE 570 Runs rich after 50 hours

It may be a dumb question but how is your air filter??

Do you know what map is in your ECU? Closed course or greenie?

The 09 bikes delivered to the US were not EPA legal, so they installed a closed course map, and the lambda sensor is not used.

If your map is using the Lambda it could be out. I have spent the last 3 years playing with the FI 990's. The last one that I was data logging had both Lambdas go off line for more than a minute at times. I also had my wide-band data logging at the same time. When they would go(at seperate times), the ECU went nuts trying to figure out what was going on. We replaced them with Bosch units and the owner reported more crisp response. The 990 uses a bigger one than the Husaberg. Bosch had a cross referance page on there sight. Don't remember if Husaberg was on there.

done measured my lambda sensor as per shop manual and... my meter tells me it down to earth, apparently I should have 6.8 - 8.0 ohms resistamce @ 20 C temp.

so does that mean its sahorted to grounfed?

It's a pretty skinny one that's for sure. Not the industry standard thread size. For that price I would go with a $60 Bosch and grind off the stock bung. Drill out and weld a new bung on. These sights here usually have whatever clip you might need if you don't want to cut the old wires and solder a new one in.

or see if someone on here has their stocker their not using after going to the comp map.

Mate,

Why not just go and have the dealer install the competition map, it will do away with the need for the 02 sensor altogether and it's one less thing that you will need to deal with.

For that matter, the 2010 green map doesn't use the lambda sensor either, so if you want to keep the green map, you could just have the 2010 green map installed.

Sorry to hear about the pub incident.

The bike will still adjust for altitude/air temp etc even without the lambda. They had to use the lambda to meet the Euro II emissions standards at the time, but, have since figured out how to get around it.

My 09 has the comp map in it from the time I bought it as the tank did not conform to EPA standards so they put the comp map in the bikes delivered to the states. The air temp sensor, map sensor, engine temp sensor etc will still adjust for altitude and temp according the input from the sensors based on the programed parameters.

If you make a big change in altitude or temp or both since the last time you rode the bike, all you have to do is let the bike idle for about 15 minutes without touching the throttle. The computer will automatically adjust to the new conditions. The dealers do this "burn in" when the bike is un crated as part of the set up.

The dealer shouldn't charge you anything for reflashing the ECU IMHO as it is just a matter of hooking it up to a computer and doing the deed. It shouldn't take very long, and I would think it would be good customer service.

Once that is done you can just put a plug in the bung and disconnect the lamda and you'll be good to go. The lambda has a heating element in it as well. There is also fault codes in the computer that will be generated if any of the wires go to ground. So by removing the lambda you will eliminate a potential problem from a device that is not in service.

Let us know how you get on. This is the first I have heard of any of the sensors on the bike going bad.

Where is the lambda sensor mounted? I can't see one on my exhaust anywhere.

2010 FE570s do not have a Lambda sensor.

On the diagrams below you can see that #28 is not present on the 2010 and the p/n for #20 on the 2010 says "W/O LAMBDA".

Thanks I will stop looking for my oxygen sensor now
The old exhaust sure runs hot on the 570
