I'm not sure what to do here. Here's my situation. Had crank run out. Sent motor for crank weld balance pin, new 107 cylinders, head work, Andrews 54 cams and throttle body bored out to 51mm. Put motor back in bike fired up and idled around 2700-2500.Pulled the P0505 code from it.. Idle air control is off. Plugs are tight and now shorts. Could then bigger throttle body be causing the iac to be off? I don't know what I can do. I do have a race tuner installed in it. Don't really want to dyno just yet as there is no miles on the new motor.. Help. Thanks

P0505 code

You made multiple changes to the motor that all change the cylnder fill rate. That would require a new map.
The code might be from an IAC issue or it might just be that the ecm is totally out of range for the map it's trying to use and that was the first thing that the logic programming came up with as the cause.
