I have a 95' 600 and I can't get the carb to quit overflowing. It's driving me nuts! When I bought the bike it ran well with the stock carb but it would just start leaking gas from the overflow at random times. I adjusted the float, made sure it wasn't hanging up and all that stuff. It would work fine in a bench test and then when you get a couple miles down the road it would just start leaking again. Well now I scrapped it and put an xrs only mikuni flat slide on. This carb is doing the exact same thing now! I have taken the bowl off and adjusted the float level on this one too but no luck. It uses a split float setup so I think if one float sticks the other should shut off the fuel. There is no pattern as to when this is happening. It may go for miles without leaking and then just decide to dump half my fuel out! The bike just got a completely new top end when I changed out the carb too. I'm not really sure what is going on and I just wondered if anybody else may know....thanks.
