Improving air flow into air box 09 570 Berg

ozberg570 said:

Thanks for that, I saw what they did on a pre 09 Berg, probably be able to do the same, however a lot of the riding I do is in very muddy / wet conditions, so i dont know how this mod would go.
I have heard you can modify top of tank flanges to allow more air flow.

Is that seat mod available for the 09 Berg?

Thanks

I think it is a mod you have to do yourself or have a seat maker do for you.

I don't know about the EFI - maybe someone who knows more could say.

The thread which mentioned taking the seat off during a dyno run mentioned that the fuel/air ratio went quite lean, so I imagine some adjustments might be necessary. How to do that with EFI I am not sure. I don't know the capabilities of the EFI tool.

There doesn't seem to be anyone playing with the EFI maps yet on this forum or they are not saying anything.


It would be good if:

Someone put the EFI bike on a dyno with an Air/Fuel Ratio meter up the exhaust and see if it runs lean when you take the air filter out. Must be a good Air/Fuel Ratio meter like Autronic, Motec, or Innovate Motorsports.

Someone dyno'd the 3 Map Switch settings to see what is happening there with Horse Power.

See if advancing the timing with high octane fuel gives more HP. I have a knock box but am not sure if the Berger motor/gearbox rattles too much to pick up detonation.

See how lean they are at Idle. Looks like Husaberg might have leaned them right out at idle to pass emission standards (That's just a guess I could be wrong).

See where the Keihin EFI changes from "Manifold Absolute Pressure" sensor mapping to "Thhrottle Position Sensor" mapping.

See if it runs lean when an Akrapovic Muffler is added. Actually see if it makes any more horse power with that on in low and high loads/rpms.

I am hoping for a dyno run in summer when the riding season is over. I would like to have a go at modifying the "Aggressive Map" if possible. Not that I need it, it's just that I like mucking around with EFI. I don't like the thought that the old skool Husaberg 6fiddees have longer legs than the FE570

Has anybody out there purchased or used the EFI Tool?

Yeah AU$1,400 seems a bit pricey for a USB Cable, and like Codemonkey say "I don't know the capabilities of the EFI tool". Husaberg don't really say if it gives the capability to fully adjust all settings in the EFI computer or just alter a few minor things.

Am also interested in the effect of taking out screw out end cap out of exhaust ( see in exhaust thread) both on a performance and and what mods are required as a result.

Don't worry, unless you wire it in the cap will fall out of its own accord. Even when I wired it the cap still unscrewed itself, so instead of an external safety wire I put the wire into the silencer with two hooks formed from the wire so that they will scrape on the pipe inside. That way I can tighten the cap every time I ride, but I probably won't lose it.

I want it to stay because I want it to serve as a spark arrestor.

I have noticed when it is out of the silencer the pipe pops more on decel.

Loctite doesn't help.

No difference in power.

I did some dyno runs a couple weeks ago. 2010 570. I think it has the Ca. green map. Usa model that I bought in the crate from a dealer going out of business. Bike is completely stock except the little screen on the end of the muffler. I usually "pack out" everything I "pack in" when I go riding but it is lost on the trail somewhere. Anyways, baseline A/F was 13.0. With the seat off it went to 13.4. Dyno is at 5,000 ft. el.
I haven't switched to the "competition map" as I want to find out if I can switch back if I don't like it. I need to install my Innovate wide-band first to see how she is tuned. I get pretty good milage if I short-shift and conserve fuel.
The programmer is pretty pricey but has some good features but doesn't have some it should have came with for $$. You can not adjust the ignition timing. It data logs and has a bunch of memory but does not log the Air Fuel ratio. There is more "cells" to adjust than the Yamaha or Honda tools. This is better but if you don't know what your doing it will get you in more trouble. I think I would rather try the comp map and see if that gives it enough fuel to do the seat mod. I ordered a DNA filter and will do a base line run again with the comp map then see what the filter can bring me. My goal is more mid range and top end without sacrificing the low end tractability. If I could get another 4-5hp with the seat mod and DNA filter I would be tickled blue :-D . Don't want to resort to a full exhaust cause more hp there will equal more noise.

you can buy a vortex x10 performance ecu which replaces standard ecu just plug in and it does ignition maps and fuel maps it has 10 allready programed in which have been tested on dyno and track tested the unit is about $860 australian with map switch that you can change on the fly you can allso purchase the software to tune it on a dyno is there any one using this ecu ? you can veiw the ecu on the vortex ignitions web site .

Are you guys racing supermoto or something? I was a little disappointed in the out put of my 570 until I realized it was just deceiving in it's power delivery. The bikes are fast, but don't feel fast. Once I stopped comparing it to my 505, I started liking it a lot more. I recently got the holeshot against a gate full of MX450s. It was a long run to the first turn too. I also like how the air filter stays cleaner and is less likely to get drowned in wet conditions.

Me? No. But I am thinking of selling my Ducati and getting some SM wheels for the 570 (among a lot of other farkles). If I put the bike on the street then I would want a bit more power - coming off a Ducati with 40 more HP (albeit on a bike that is 200 pounds heavier) has accustomed me to wanting the bike to have a certain amount of power above 60 MPH - especially in traffic. The 570 as it sits doesn't have that.

Also, I really want one of these for the winter:



and snow takes a lot of power - from what I have read it feels like you have about 50% less power.

For my trail riding I don't need more power - I have plenty there.

I didn't see anything on their site about EFI or Husaberg.
