In my understanding, an erratic idle should be from an intake leak. My '05 has in increasingly erratic idle, to the point that it has shut off on decel a few times, not what you want to happen approaching a turn or in heavy traffic. This '05 (bought in early '06) is a daily rider and has been since new, it will turn 30k this coming week, and I have faithfully synched the carbs at every recommended service interval. They are never more than a tiny, tiny bit off. I know that an intake leak can be detected by spraying something flammable near the carbs while it's running. When I do this with carb cleaner, I get absolutely no reaction, no revs increase at all. My lines all look good and healthy, I have never removed the carbs, never (thank goodness) had to mess around the fuel system at all, until now. I keep the idle setting right around 1000 RPM but now it's jumping around 100 or more to either side of that. Doesn't matter if the bike is hot or cold. Anybody got any idea what's going on with my idle? The shut-offs are kinda disturbing and I'd sure appreciate anything you folks have to offer...
