We had a problem just like the one listed here. It ended up being a broke engine case that was sucking air and wouldn't let it idle down. I agree with the post above that with all the work stock jets are not probably good enough, but I am not sure that would affect your idle. Usually when it will not idle down there is an air leak somewhere.

With the overbore, aftermarket pipe and new reeds I bet your running very lean with stock jets.
Definatly check all conections and make sure everything is sealed correctly, but I'd bump the jets up maybe 2 sizes and work your way down. Always better to be rich than lean.
What mods have you done to the intake? Aftermarket filter? open airbox?
