Carbs on long trips

What kinda issues am I gonna run into (if any) with power loss with a carbed bike? I know with EFI it auto adjusts and obviously I'm not gonna stop and adjust my carbs for every elevation change

will it even be that big a deal? just kinda wondering what to expect.

You will prolly not notice much, as long as your bike is in good running order to begin with. You can figure out the appoximate horsepower loss with this calculator. http://www.webcalc.net/calc/0757.php Less airflow means less mixture, means less power.

That should be the only really noticable result.

ok... I was figure'n the only thing I'd loose was a bit of HP just wasn't sure how much... and if it'd be that big a deal...

Thanks!

uh... when I use that link and set it to


Elevation 14000
BHP at sea level 100

Brake Horsepower loss : 420


shit!

even setting at 1500 feet it says I loose 45hp...

somethings wrong

I have a 96 CBR600 F3 with 32,000 miles on it. I took a 800 mile weekend trip a month ago(By myself and 100s of miles from anyone I knew). Which I went from Atlanta, GA to Augusta Georgia in which you go down in elevation. Then I rode from Augusta to Deal's Gap and ran the dragon in the same day. Then the Cherohola (which does reach over a mile at one point) the next day and back to Atlanta including riding in rain the entire way back.

Infact here it the route from Augusta to Deal's Gap that I took...

I didn't notice any problems with the bike nor a performance loss(even with my carbs tuned for Full exhaust and having stock exhaust on it). I felt like the exhaust got quieter when I went in up in elevation fast but my friends with their EFI bikes(Not at the gap but another mountain) noticed teh same thing with theirs.

Of course comparing my mountains to your mountains would be like comparing Paris Hilton's breasts to Dolly Parton's breasts. You just can't.

I think your bike would be fine but maybe do some test runs up a very tall mountain to see how it really feels. Also my buddy's GF just got a brand new ZZR600 and those things are freaking sweet. Even though they are carbed.

Oh yeah. If it hasn't already when you clicked on it put it in "Terrain" mode when you go to the Google Maps.

the "new ZZr600" is what I have... yeah the carbs are awesome... I've ridden several FI bikes that weren't any smoother...

I am hoping to get an internship out in CO this summer up in the mountains a little bit so I'll have to check out what it will be like. When are you planning on being there?

I just like how smooth the bike shifts. Which when she first got it she let me ride it for a while to help break it in. I put 50miles on it and fell in love with it. Of course I stalled it out and almost had it fall over at a light. No thanks to the RC51 in front of me with FMF pipes that thunder so I couldn't hear the bike(Nor could I feel it).

Shifting on my old F3 requires muscle work. Especially getting from 1st to 2nd(Don't even consider power shifting in there). I guess 32k on the odometer doesn't help either.

Which I have to say Kawasaki has it going on this year.

psst... the 05-08 ZZr600 is the 00-02 Zx6R just renamed
