you all a bunch of post whores!!!

WIthout the O2 sensor feedback, the FI is just a guess.

I know the newer BMW engines that are FI use an O2 sensor.  I assume that is for closed-loop control of the FI, like a car.   I think these are generally fitted with a 3 way catalyic converter.

I don't know if this required to meet the current ECE standards or if they're just aiming to meet the "harmonized" US and ECE standards that rea scheduled to hit in the 2010 model year.  

The results of the certification tests are posted on EPA's website, and the BMWs have low emissions.  But I think all of the bikes with 3 way cats do very well.  I guess that's the shape of the future.

Thumperclone,
The rule of thumb is -every 5000ft up in elevation- 1 size down in jet size. If You are only going to stay 1 day in higher than Your elevation , in my opinion it is not worthed to get dirty. The bike will still perform OK. In Your case it is only one size difference, compared with Your residence. Just think about all the guys, that come from the low planes and go to the high mountains- how many of them do You think, rejet in the way up ?
About the FI, Cat's and all that crap- Yes , unfortunately this is  is the future- SMART VEHICLES FOR STUPID PEOPLE.  This is what the SYSTEM wants - You pay more, You work more, more money change hands- more money for the parasites.
