Hiya!
I recently brought an FZ750 back from the grave,
I cleaned the carbs, went through the ignition system, rebuilt the brakes, etc etc.
After turning it over about a billion times it now runs but it won't idle down. It's idling around 2k rpms. Further, if I even twist the throttle a single degree, it will act as if I just gunned it reving up to 8 or 9k then slowly settling back down to 2k.
The throttle cable is free moving and not pinched, the idle screw seems to have no effect except to increase the idle even more.
I checked for vacuum leaks on the intake boots by squirting wd40 around each one with no change in behavior.
I can see the choke lever operating the rod back and forth but I don't know what the choke lever actually does inside the carb. When I opened the carbs up to replace the needle jets they were pretty clean, none of the jets (main or pilot) were clogged and the slides moved freely. the diaphragms appeared to be in good shape.
Does this sound like anything in particular? Stuck slide? Stuck choke? Clogged something?
Any suggestions?
Thanks!
