First thing I'd do in your shoes is to reset the "0" and the "100 %" throttle position to insure that is not your problem. The instructions are clear on how to do that.

My guess would be the idle speed is set too low. You shouldn't idle an EFI Harley less than 950 or so. His motor is not pulling enough vacuum to pull enough air into the throttle neck to mix with the fuel and burn properly at idle. It's gasping for air.
