I'm having an issue with the idle on my yz. It is real inconsistent, high then low. Sometimes when I come into a corner pull in the clutch and the idle drops all the way to nothing and it dies. I have cleaned the piss out of the carb, made sure all the vent hoses are not plugged. The reeds are not cracked or chipped. Jetting is good, and it runs great above idle. Any ideas??
