well smitty, I don't want to lower it too much, just a little. listening to other efi harleys at idle, it seems like mine is idled a little too high. It sounds different when it's completly warmed up. Kind of like a sewing machine, if you know what I mean. This is my first efi harley and I bought it used. It is a stock 2004 road king classic with 8k on it. I actually thought about converting it back to a carb because of this and also because of the tuning issues that you read about. I don't want to be dependant on a shop somewhere everytime I want to change something.
