Improving air flow into air box 09 570 Berg

I have heard you can drill / slot / the flanges on the tank to improve air flow into air box, I heard it improves hp? but do you have to have a look at the FI Mapping?

Dont really want to modify? bike unless its worthwhile........


Thanks

Re: Improving air flow into air box 09 570 Berg

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.

Thanks for the advise,
Will look at purchasing 2nd seat and modifying it to suit, do you know if I will have to have a look at the FI mapping?

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

Re: Improving air flow into air box 09 570 Berg

Thanks Davo,
Like yourself just would like to know how to get the best out of the Berg without hurting it.
Would like to Measure the effect of the mapping tool as I am yet to fit it, as I find I already get great throttle / traction control as is.
I know you can get a mapping tool to adjust FI from Husaberg, I think they are around AU$1400 ea.
I will find out a little more before carrying mods.
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.
Cheers

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.

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.
