Somebody bought one ?

Not yet would be interesting to see the results.:icon_razz:

There are in holidays�
Sure, I will tru soon :tongue1:

A lot of money for a rubber ring with a great big hole in the middle, don't you think?

That bloke is really really taking the proverbial. I don't like it when a retailer speculates on the consumer just because they have an exclusive product. That Thorsten, is not my mate for sure. :mumum:

I'm sure you could make something very similar by taking a Stanley knife to the snorkle section on your original one? (that's what everyone does with Honda XR400s... x)

Exactly. I was staring at the pic for a long time and wondering what the big deal it was. Besides, my experience tells me so far the additional air intake significantly increases the gas consumption, i.e. by a 100km give or take. Can it be that much?

You've got it in one Jenny, if you don't know Thorsten at O-T-R the best way to descrive him to you is to compare him to one of those annoying egyptians in Cairo with carpets rolled over their shoulders, pockets full of moody Rolex watches and Mont Blanc pens trying to flog them to you and following you for miles until you buy one just to get rid of them. :toothy10:

No rocket science here, all they has done is add a second intake & move the intake to the back of the air box. It is well known that the XT motor loves more air flow & the cooler air will make a difference.

I did this mod to the XTX/R's a few years ago by drilling 30mm holes in the air box pre-filtered chamber. Once I can get my hands on a XTZ I am sure we will see a few mods from me, I am sure I could come up with something for the air box at half that price.:Tennis_ABHMXO:

If you add more air, then the EFi will correspondingly add more fuel to keep the air/fuel ratio the same (I believe the optimum is around 14:1) for correct combustion and therefore yes, if you increase the airflow by a certain percentage, then you can expect the fuel consumption to go up by a certain amount too...

Kev - to clarify, the new OTR part simply replaces the original and fits over the same aperture in the top of the airbox, it's not a second intake - it just scavenges from under the seat area rather than from directly behind the cylinder...

The optimum A;F ratio for the XT in power & fuel economy is around 13:1, having a the XT motor running at 14:1 may be good for emission control but this does not mean it is the best air/fuel ratio.

I am a little confused, if you are removing the standard intake & replacing it with a new intake in the same postion how does it change the intake point from behind the cylinder to under the seat. Going by the picture from OTR I can't see how it will make any difference unless they are not showing all the parts to be fitted & saying it is a stage two is well off the point, a stage 2 intake would mean there would be two intakes one would think.
