stumble off idle
I have a 96 fzr600 and it runs great except for a stumble right off idle. Pulled the carbs off, bench synced them with feeler gauges and ran the pilot screws out to 3.5 turns. Pulled a few bowls and everything looks good inside, pulled a few slides and can see someone shimmed the stock needles with washers to make up for the k&n air filter. Put it back together and still stumbles. An unrelated problem, the slide on #3 stays up, doesn't return like the rest...feels like there is a vaccuum staying in the diaphragm. Any help will be greatly appreciated as I am not putting the bike back together till I sort this out. Thanks guys.

Re: stumble off idle
Ok, figured out what the slide problem was, I left the spring on the bench 
put the bike back together because I was tired of not riding it. Still curious about my stumble.

Re: stumble off idle
The stumble is even there if you dial up on the idle screw. There's just a dead spot in the throttle right off idle.

Re: stumble off idle
Yeah, as soon as I let out the clutch and twist the throttle it runs great but it hesitates a little and that sometimes causes me to stall. A few cap fulls of sea foam seems to be smoothing it out.

Re: stumble off idle
Maybe ill check my float height, that has a lot to do with off idle fueling.
