Finally, thank you Keith, I could not have said it better or as good

As far as reference material goes, I have a PDF service manual for 98-06 600cc, would the diagrams be the same for the 750? Most everything else seems to be the same or damn close.

DAMN..that's a lot to take in but very helpfulfor what I'll have to deal wth. Thank you

I am trying to sync my carbs 1100 for a Kat 92". I have already disassembled my carbs cleaned and re-assembled. For some reason I was unable to get my bike to start as if it was not getting any gas. I can spray started fluid into the carbs and the bike fires up like a pro until the fluid runs out and then the bike cuts off. I have replaced all my hoses and am going to go back into the carbs. I am wondering if theses carb setting will also work for the carbs I have. Any Ideas anyone

1127 engine ? I doubt your settings would be the same ..... But if it's only running on starting fluid , yeah , you ain't getting fuel . Not even with the choke on ? Should at LEAST run that way ..... The plugs smell like gas ? Try it on prime ? SURE you cleaned all the crap out ?

Clogged idle jets or something in the pilot circuit. The main jets are only used when the throttle is open.

But the mains DO have ne effect on other parts of the system . They'll effect how much gets through the pilot circuit , as well as what can get "around" the needels .

More air = more turns out!) (BE CAREFUL! ¼ turn makes a BIG difference!)

??? is this right i thought it was other way around ???

You are correct , sir . More turns out add more FUEL .

[Villu_EST]

Wait... wait, wait, so, which is it then ? AFAIK the more you turn the mixture screw out, the more lean the mixture gets .. ?
Coz, when i first set my Kat to 0,7 turns out, it almost shot fuel out of the exhaust. But now the A/F mixture screw is 2,1 turns out and she runs much better.

[steves]

0,7 and 2,1? Huh?

The more you turn the screw out, the richer the mix.

[Villu_EST]

Are you sure ? Richer as in the engine gets more fuel than air ? I mean, AFAIK, if you turn the screw out, then more air goes through the tubes and it resists fuel (braking-air if I translate it rough from my language). Damn...
Now im extremely confused. Thing is, my bike took 10 liters to 100km so I was sure the mixture was too rich. And the exhaust fumes smelled like pure gasoline. With 2,1 turns out, it doesn't smell almost at all. :/ But, the tank seems to get empty as quick as before.

Well , my bike () was ALWAYS really rich . Sometimes smelled like DIESEL . Black plugs , black exhaust . Now that I figured it out , it doesn't reek like it used to . However , my mileage has not drastically improved as I'd hoped . It seems like under SOME circumstances my milage may have gotten a tad better , but on average , it's still fairly close to what it was when I was still REALLY rich . To get TRULY bad mileage , I had to be hitting on 3 or less cylinders .....

this thread is very interesting

I just got my kat, and the guy I got it from told me he cleaned the carbs.
After getting such sucky performance and gas mileage, I figured that this guy was lying.
I took the carbs out, and they're almost SPOTLESS!
but the bike is running VERY rich, so that means I have to adjust the A/F screws right? ('92 750)
