Not a full review, but all I've seen so far.

everyone knows, 06 fastest by far

[I`m Batman]

How much more power can they squeez out of that thing???

That's what all the rest must be thinking!:lol:

Actually, they haven't even approached F1 levels of bore/stroke and hp/liter yet. Plus, all the mfg's want to be just incrementally ahead, so they have more to squeeze out fairly easily next year. The low-hanging fruit, so to speak.

[Knuckle Dragger]

Well that is one nice bike, the power toggle option would be cool to have.

Yep. It's even got a "reserve" toggle........:lol: :p

Yea Yea yuck it up it will be a long time before I live it down

I always thought that would be a good idea, too bad they don't have a switch for high and low altitude that makes changes to the ignition, injection or better yet an altimeter that makes the adjustments for you.

Don't need it, the system compensates via barometric pressure if I remember correctly.

They are suppose to do that but what I have been told is they don't. But I am not sure so don't go technical on me.. :) this is what those who have dynos and program powercommanders and such tell me.

I won't go all technical on ya if you don't go all religious on me!:lol: Don't make me trump your bible with my shop manual!

I think they're full o' shit. I bought mine in Cleveland at 200-ish ft, and rode it up to trailridge from here, so it's seen about 12,000 elevation change, with the expected power loss from altitude, but it still ran good. There's no way it was running the same fuel mappings from Cleveland. Plus I know there's a pressure sensor. Besides, how the fuck would they know? Do they have a atmospheric chamber to test the bikes on a dyno in? I think not.

[~Barn~]

EFI and it's associated electronics are constantly adjusting itself to internal and external variables for the purposes of tuning itself for just the right mix of performance, emissions, and fuel consumption. Elevation obviously is a key factor in the equation.

Now keep in mind that I use the words "just the right" loosely, because it's not a 100% perfect formula, but for streetriding purposes, it's pretty good. And again, it is not a performance tune, it's a combination of all of the above. Either way though, within a few minutes of riding, a current-day EFI bike will compensate thusly, to perform at it's quote/unquote "optimum", as defined by the manufacturer. And it will do this whether you're just off the beach on HW1 in Monterey or just off the ski lifts on I-70 in Vail.

Have I ever thumped you with a Bible? :) I was told that the presure is read from the exhaust and that it does not do as good a job at altitude and that they are rich anyway and going up in altitude only makes it worse from what I remember. They don't have chambers but they do monitor the exaust gas and make changes according to what the pressure sensor reads. I can't win this debate Frank because I have no knowledge, you would have to debate people who do it for a living to find out. Let me know if you do.

[Carlsbad]

The 7K is a bad mf-ing bike in sheer numbers no doubt. If it wasn't so fugly I'd own one :)

From the front, it looks like the blue power ranger LOL. It has never been a looker, but then it never has had to be, but if it was I bet they would sell more.

I like "Fugly"

baro pressure is read from a sensor
airbox pressure is read from a map sensor
on a stock bike a/f is read from the O2 sensor (in steady state only)

DJ have a bar mounted switch where you can toggle between two maps like high/low altiude

[Jackal]

I decided to pass the new models.... Literally...

I think the older models like my '01 don't have the O2 sensor. I'm actually not even sure that the new FI systems are closed-loop yet (requiring the sensor). In this regard, I think most cars are more advanced.

[Clarkie]

yeah sorry talking about the new fi bikes in general, they adapt but like you said arent as smart as car fi systems
